Messenger (satellite communication system)

"Messenger"- Russian multifunctional personal satellite communication system (MSPSS), built on the basis of low-orbit spacecraft. The purpose of the system is to provide communication services on a global scale. The system is being developed by order of the Federal Space Agency of Russia. The main developer is the operator and the operating organization - OJSC "Gonets Satellite System".

System composition

At present, the Gonets-D1M system is in trial operation. The space segment is a constellation of 5 low-orbit spacecraft (2 1st generation vehicles "Gonets-D1" and 3 2nd generation vehicles "Gonets-M"). The ground infrastructure consists of a system control center and four regional stations in various regions of Russia (the European part, Southern Siberia, the Far North and the Far East). In 2011-2015. it is planned to deploy the Gonets-D1M system, which includes up to 16 spacecraft and 7 regional stations. An increase in the number of spacecraft in the system will significantly improve its tactical and technical characteristics, such as the waiting time for a communication session and the time for delivering information.

At the moment, it is planned to launch 8 Gonets-M vehicles with 3 launches. The first launch is scheduled for February 15, 2013 (3 Gonets-M vehicles # 14, 16, 17). The next satellites are planned to be launched in Q1 2014.

The Gonets-D1M system is being created within the framework of the Federal Space Program of Russia for 2006-2015. At JSC "Information Satellite Systems" named after academician M.F. Reshetnev "ordered 8 new satellites" Gonets-M ". The next generation of Gonets-M1 satellites will also be developed there.

Purpose of the system and services based on it

The main purpose of the "Gonets" system is both the transfer of packaged data between the system subscribers and the provision of communication between subscribers and public networks. The equipment and software of spacecraft and subscriber terminals are designed in such a way that the system does not require continuous presence of subscribers in the radio visibility zone of the spacecraft. In the absence of radio visibility, the message is buffered in the subscriber terminal or in the spacecraft and transmitted as soon as possible. At present, the following services have been implemented on the basis of the Gonets system:

• data transmission globally
• determination of the location of a mobile object and transmission of coordinate information
• personal communication between subscribers of the system on a global scale
• transmission of circular messages to subscriber groups
• collection and transmission of telematic information
• construction of departmental communication subsystems

The subscriber terminals of the system are produced in stationary and mobile (for installation at a mobile facility) execution. The main weight and size limitation of the subscriber equipment is the size of the antenna, which in the mobile version has a round body surface with a diameter of 216 mm.

In the event that the sender and recipient of a message are within the coverage area of ​​the same regional station, data is transmitted directly between their terminals by means of a spacecraft. If the sender and the recipient are in different regions, the data is transmitted from the sender through the spacecraft to the nearest regional station, then through the ground communication channel to the recipient's regional station, and then from there through the spacecraft to the recipient's subscriber terminal. It is also possible to transfer data to an Internet address.

The delivery time of a message currently ranges from one to two minutes, if the sender and the recipient are in the field of view of one spacecraft, up to 6 hours. With the further deployment of the orbital constellation, the maximum information delivery time will decrease.

Applications and consumers

The use of the Gonets satellite system is typical for mobile satellite communication systems:

• communication in remote regions
• transport monitoring
• monitoring of environmental and industrial facilities
• disaster communications
• communication in the interests of various departments and ministries

The main users of the "Gonets" system at present are both state structures (Border Troops of the FSB of Russia, the Ministry of Internal Affairs of Russia, the Navy, etc.), and commercial organizations and industry enterprises (JSC "Roshydromet", FSUE "SNPO" Eleron " , Research Institute of the Arctic and Antarctic, State Institute of Applied Ecology, Sakhalin Environmental Company LLC, etc.).

Typical application of MSPSS "Gonets-D1M" is the collection and transmission of sensor information from stationary or mobile objects in hard-to-reach areas (for example, monitoring of drilling rigs, meteorological stations, transport), the transfer of confidential information between remote subscribers, as well as the collection and transmission of information about the location of mobile objects (transport). System-based services are provided globally.

Detailed information about the "Gonets" orbital system and the services provided -

Structurally, the Gonets-M1 spacecraft consists of the following main elements:

• service systems module (platform) - developed by JSC "ISS";
• payload module (PN) - developer THALES.

The structure of the spacecraft body - non-hermetic design is made in the form of a rectangular prism. The power base of the spacecraft body is four longitudinal struts and honeycomb panels. The panels located along the + ОZ and -ОХ axes are the spacecraft payload panels; they are used for the devices and equipment of the repeater and the antenna module, respectively. The rest of the panels house the equipment of the spacecraft service systems. Since the spacecraft orientation is organized in such a way that the spacecraft XOY plane coincides with the Sun-object-Earth plane, and the spacecraft axis (ОХ) coincides with the radius vector, the spacecraft body planes located along the + ОZ, -ОZ axes are constantly in shadows, which creates the most favorable conditions for their use as radiation surfaces for the release of heat located on them onboard equipment. On the panels located along the + ОZ and -ОZ axes, the equipment of the service systems and the equipment of the repeater with a large heat release are installed.

The spacecraft has the following composition of antennas:

• 1 antenna D1;
• 6 antennas D2;
• 1 antenna D3;
• 2 C-band antennas;
• 4 KIS antennas;
• 4 NAP antennas.

D2 antennas are placed on reclining structures made of honeycomb panels, which transfer them from the starting position to the working one. The transmitting antenna D1 and two C-band antennas are installed permanently on the upper plate of the PN. Antenna D3 is installed permanently on the central tower (structural element of the PN). The KIS antennas are located in pairs on the upper panel of the PN and the lower panel of the instrument compartment. NP antennas are located on the lower panel of the instrument compartment. The solar battery consists of two wings, each of which is mounted on a rotary device, which provides, for orientation of the solar battery to the Sun when the spacecraft is operating in orbit, its rotation around an axis parallel to the axis OZ of the spacecraft. The propulsion system of the correction system is installed in the software along the -OY axis, the line of thrust action passes through the center of mass of the spacecraft. The thrust vector is directed along the -OY axis of the spacecraft, which, when issuing a correction pulse, is oriented in the spacecraft's orbital plane. The optical devices of the attitude control system are placed in such a way as to ensure the required location of their fields of view: POZ - to the Earth, POS - along the -OY axis and + ОХ SC, DMDS along the axis (-OY SC). The magnetometer is mounted on a hinged bar.

With the help of the ISSR "Luch", information is exchanged in real time between the spacecraft objects, primarily the Russian segment of the International Space Station, and their flight control centers. Today, the Luch-5A, Luch-5B and Luch-5V repeater satellites, which make up the Luch orbital grouping of the ISSR, provide the ability to continuously communicate with the Soyuz-MS manned transport spacecraft and transport cargo ships Progress-MS during launch, flight, docking with the Russian segment of the ISS, undocking and landing of descent vehicles.

ISSR "Luch" provides the ability to control launches and flights of launch vehicles (launch vehicles and booster blocks), implementation of technology for controlling missile-technical facilities from flight control centers outside their radio visibility zones.

The ISSR "Luch" is tasked with transmitting signals from emergency beacons to data collection centers of the international space search and rescue system COSPAS-SARSAT and signals from data collection platforms at the Roshydromet information receiving station. In addition, the ICSR "Luch" is used to transmit corrective signals from ground differential correction and monitoring stations to users of global navigation systems.

The "Luch" retransmission system also makes it possible to carry out TV reports and implement video conferencing.

The multi-functional space relay system of the ICSR "Luch" was put into trial operation in February 2016.

Navigation

The creation of navigation satellites of JSC "Information Satellite Systems" named after academician M.F. Reshetnev ”has been working since the 1960s. Today the company is the only domestic enterprise where satellites for this purpose are designed and manufactured.

Currently, space navigation in Russia is provided using the GLONASS Global Navigation Satellite System. ISS JSC acts as the lead developer of its space complex, which includes satellites and a ground control complex. The GLONASS system is designed to form a continuous field of navigation signals, with the help of which it is possible to accurately determine the coordinates and speed of movement of objects equipped with special receivers. Its stable work is the key to the successful solution of many defense, economic, social, scientific and production problems.

The GLONASS system is based on 24 spacecraft in an average circular orbit with an altitude of 19100 km. They are located in 3 orbital planes - 8 satellites in each. In addition, the orbital and ground reserve of space vehicles is a guarantee of the stable operation of the orbital constellation.

Today the GLONASS system includes modern satellites "Glonass-M", designed and manufactured by the "Information Satellite Systems" company named after academician M.F. Reshetnev ". They provide navigation signal coverage of the entire globe. The enterprise also creates promising spacecraft "Glonass-K", the first of which has already been launched into orbit and is undergoing the stage of flight design tests.

Glonass-K

Glonass-K is a promising spacecraft of the GLONASS Global Navigation Satellite System. Compared to their predecessors, the Glonass-M satellites, they have improved technical characteristics and an extended active life. Their main difference from the previous generation satellites is that, in addition to emitting frequency division navigation signals in the L1 and L2 bands, they will also emit a civil code division division navigation signal in the L3 band. This will significantly, up to tens of centimeters, improve the accuracy of navigation determinations.

Glonass-K satellites are multifunctional. A special radio-technical complex is installed on board to operate in the international search and rescue system COSPAS-SARSAT in distress.

The first spacecraft of this type was launched into orbit in 2011, the second in 2014. Currently, JSC "ISS" is also developing advanced navigation satellites - "Glonass-K" of the second stage.

The new generation navigation spacecraft Glonass-K are launched from the Plesetsk cosmodrome by the Soyuz-2-1b launch vehicle with the Fregat upper stage.

Glonass-M

Satellites "Glonass-M" form the basis of the orbital constellation of the GLONASS system. They provide navigational information and accurate time signals to land, sea, air and space users. Devices of this type continuously transmit four navigation signals with frequency division in two frequency bands - L1 and L2.

Operating as part of 24 Glonass-M spacecraft, the Russian global navigation satellite system ensures the location of objects with an accuracy of about 5 meters for civilian consumers.

The Glonass-M spacecraft are launched into orbit one by one by the Soyuz-2 launch vehicle with the Fregat upper stage from the Plesetsk cosmodrome or as part of blocks of three satellites by the Proton-M launch vehicle with the Fregat upper stage. Breeze-M "from the Baikonur cosmodrome.

Geodesy

The cartographic model of the Earth needs to be periodically updated, and its geophysical parameters must be regularly updated. These tasks are solved using space geodesy.

JSC "Information Satellite Systems" named after academician M.F. Reshetneva ”is the only enterprise in Russia where geodetic spacecraft are developed and manufactured. The company's modern project in this area is the creation of the GEO-IK-2 satellite system.

GEO-IK-2

Company "Information Satellite Systems" named after academician M.F. Reshetneva "is responsible for the creation of a new generation space geodetic system based on the GEO-IK-2 spacecraft. They will make it possible to carry out geodetic measurements of high accuracy and thereby meet the needs of Russian science in updating the cartographic model of the Earth and refining its geophysical parameters. The orbital constellation of the system will consist of two satellites.

Purpose of the GEO-IK-2 system:

• construction of a high-precision geodetic network in a geocentric coordinate system;
• solving a number of applied problems requiring the prompt determination of the coordinates of ground points, including:
  • creation of regional geodetic networks;
  • remote sensing of the Earth;
  • determination of the marine geoid;
  • monitoring of ice conditions.

The satellites will be launched into a working sun-synchronous orbit with an altitude of about 1000 km and an inclination of 99.4º by a Rokot launch vehicle with a Briz-KM upper stage from the Plesetsk cosmodrome.

Research and experimentation

Before being used in spacecraft, new technologies, devices, materials need to be worked out and received flight qualifications. To solve this problem, small satellites are well suited, which are launched into orbit with a passing load, have a low mass and low cost. Such spacecraft are also developed and manufactured at the Academician M.F. Reshetnev ".

ISS JSC attracts representatives of other enterprises, scientific organizations, teachers and university students to the process of creating small spacecraft. Thus, during the implementation of projects, not only scientific, technical and experimental, but also educational tasks are solved. This makes it possible to train teams of young specialists with practical experience in creating a satellite - from developing design documentation to controlling a real spacecraft during operation. This educational method is called project-oriented learning technology, and satellites, in the design and manufacture of which representatives of universities took part, are often called student satellites.

Anniversary

The small research spacecraft "Yubileiny" was created at JSC "ISS" as part of the campaign to celebrate the 50th anniversary of the launch of the first artificial Earth satellite. It is designed to transmit sound messages, as well as photo and video images, telling about this significant date and other important events taking place in the space industry. On board the spacecraft, a radio channel is organized in the international experimental and amateur radio frequency range of 435 MHz and 145 MHz. The data transmitted with its help are received at any point on the Earth during the passage of the spacecraft in the radio visibility zones above them.

During the creation of the Yubileiny, JSC ISS developed a promising multifunctional non-pressurized satellite platform, which formed the basis for the subsequent small spacecraft of the enterprise.

The satellite was launched on May 23, 2008. The project resulted in a number of applied experiments, including testing in space a magnetic-gravitational orientation and stabilization system, new devices for orientation to the Earth and the Sun, new configurations of gallium arsenide solar panels, and nanocoatings for radiation protection of on-board instruments from cosmic radiation.

Peace

The scientific and experimental spacecraft "MiR" was launched into orbit for testing promising developments in space. As a result of his work, flight confirmation of a number of the latest technical solutions of ISS JSC, as well as other related enterprises and organizations, was obtained. In particular, new materials, promising elements of thermal control, power supply, orientation and stabilization systems have proven themselves positively. During the launch of the satellite, an experiment was carried out with a survey camera, and during its operation - with a remote sensing camera of the Earth, as a result of which more than 350 images of the surface of our planet were obtained with a spatial resolution of 250 m per pixel.

MiR is designed and manufactured on the basis of the same unified platform as the Yubileiny spacecraft. This is the second satellite created with the involvement of teachers and students of the Siberian State Aerospace University. The spacecraft got its name in honor of the founder and first head of the enterprise, Mikhail Reshetnev.

ISS-55

At present, the specialists of the "Information Satellite Systems" company named after academician M.F. Reshetnev "are working on the project of a small ERS spacecraft of high spatial resolution and multispectral imagery" ISS-55 ". It is intended for multi-zone remote sensing of the earth's surface in order to obtain highly informative images in the visible and infrared ranges of the electromagnetic radiation spectrum, to ensure prompt delivery of data via a radio channel, to process and provide information to a wide range of consumers.

ISS-55 is being created on the basis of the new universal platform NT100-01, the configuration of which allows the use of spacecraft to solve the problems of high-precision imaging of the Earth's surface in the visible and infrared ranges, as well as to re-target the satellite, if necessary, to survey objects not covered by sub-satellite swath. The payload mass of the spacecraft will be about 50% of the total satellite mass equal to 180 kg.

The main target equipment of the ISS-55 satellite is optoelectronic equipment of high spatial resolution with a resolution of less than one meter. In addition to it, the spacecraft will be equipped with a multispectral imaging system of medium spatial resolution with a resolution of less than thirty meters, including a Fourier video spectrometer and an infrared imaging system.

The information obtained with the help of the ISS-55 satellite can be used for monitoring emergency situations, mapping and controlling water resources, in land use, agriculture and forestry.

The launch of the spacecraft is scheduled for late 2015.

Based on the Closed Joint Stock Company (CJSC) "Satellite System" Gonets ", formed in 1998.

The company is engaged in the development, production, management, operation and provision of communication services of satellite systems, including the sale of terrestrial telecommunication equipment, the implementation of scientific and technological achievements in the field of communications,

OJSC "Satellite system" Gonets "is the operator and operating organization of the multifunctional personal satellite communication system (MSPSS)" Gonets-D1M ".

The ground infrastructure of the system consists of the System Control Center, the Communication Complex Control Center, central and regional stations, the Flight Control Center, and the Ballistic Center. Ground stations MSPSS "Gonets-D1M" are located in Moscow, Zheleznogorsk (Krasnoyarsk Territory), Yuzhno-Sakhalinsk and on the Tiksi Peninsula.

The diameter of the radio visibility zone of each regional station of the system is about five thousand kilometers, which makes it possible to provide 100% coverage of the territory of Russia, as well as most of the territory of Europe and Asia.

Work under the program of a personal satellite communication system based on low-orbit spacecraft of the "Gonets" type was started in 1991. In July 1992, two spacecraft of the Gonets-D demonstration project were launched and a network of ground subscriber stations was deployed. This made it possible for the first time in the world to demonstrate a working prototype of a communication system on low-flying spacecraft.

In 1998, on the initiative of Rosaviakosmos, the head organization for the creation of the Gonets NSPSS was established - the Gonets Satellite System CJSC. The deployment of the system was carried out in order to demonstrate the possibilities of transmitting various kinds of information in the interests of government consumers using LEO satellites.

After the successful launch of three spacecraft (SC) in December 2001, nine SC "Gonets-D1" function in orbit.

The control of the orbital constellation of the spacecraft and the functioning of the communication complex are provided by the subdivisions of OJSC "Satellite system" Gonets "and its branches in Moscow, Zheleznogorsk of the Krasnoyarsk Territory, Yuzhno-Sakhalinsk. Since 1998, cooperation with enterprises of Kazakhstan has begun - a project to create a Kazakh segment of the NSPSS" Gonets ", within the framework of which a regional station of the "Gonets" system was deployed near Alma-Ata.

To complete the construction of the constellation, it remains to put three satellites into orbit, the launch of which

By the decision of the Federal Space Agency dated December 30, 2011 on the organization of work on the control of spacecraft of the Multifunctional Space Relay System (SC MKSR) "Luch" JSC "Satellite System" Gonets "was involved as a co-executor for work with the SC MKSR" Luch ".
