To solve the target tasks, a small-resolution multi-zone scanning device (MSU-MR) is installed on board the device for round-the-clock shooting of the Earth in the visible and thermal ranges of the spectrum, a module for temperature and humidity sensing of the atmosphere and a heliogeophysical equipment complex for measuring solar activity. The digital data terrestrial surface produced by this equipment is used to predict and respond to natural disasters and emergencies, and, thanks to more accurate weather and natural events forecasts, ensure development. agriculture Russia

Our equipment at Meteors makes it possible to track the dynamics of many hydrometeorological parameters. With the introduction of this device into the group, the frequency of shooting the Earth will increase, the reliability of receiving meteorological information by Roshydromet ground stations will increase. So we will improve the quality of weather forecasts on a regional and global scale, we will be able to give new estimates to the transformations of climate processes, said the head of the system design sector of multi-zone scanning devices RKS Aleksander ZAYTSEV.

"Meteor-M" is equipped with on-board command and measurement system RKS. It provides satellite interaction with ground control stations, receives and processes command and program information from the Earth, broadcasts it to other systems and instruments inside the spacecraft, and also transmits telemetry data on the current state of the satellite back to ground stations. RCC specialists also manufactured a system for collecting and transmitting technical data and an on-board information system with a meter band radio link, transmitting large amounts of information with a very high signal frequency level. As part of the spacecraft, a rescue radio complex created in the RKS holding for relaying signals of emergency radio beams of the international satellite system COSPAS-SARSAT is operating.

During operation, Meteor-M No. 2-4 will provide electricity to solar panels with an area of ​ ​ 31.59 sq. meters developed by NPP Kvant (part of the Russian Space Systems holding).

Information support for the launch of a launch vehicle with a satellite was provided by a set of measuring, collecting and processing information from the Vostochny cosmodrome, created by the Russian Space Systems.

2023: Equipping the command and measurement system of the Meteor-M satellite No. 2-3

Onboard systems and complexes of the Meteor-M satellite No. 2-3, developed at the Russian Space Systems holding (RKS, part of the Roscosmos State Corporation), will increase the efficiency of the Russian orbital group for remote sensing of the Earth (DZZ). This hydrometeorological apparatus for environmental monitoring of the Earth was launched on June 27, 2023 from the Vostochny cosmodrome. This was reported to the RKS on June 28, 2023.

To solve the target tasks on board Meteor-M No. 2-3, a small-resolution multi-zone scanning device (LCS) created in the RCS for round-the-clock shooting of the Earth in the visible and thermal ranges of the spectrum, a module for temperature and humidity sensing of the atmosphere and a heliogeophysical equipment complex (GGAK) for measuring solar activity. The equipment will allow obtaining digital multi-spectral images of the earth's surface for predicting and eliminating natural disasters and emergencies, as well as, thanks to more accurate forecasts of weather and natural phenomena, will ensure development agriculture Russia.

The multi-zone weather satellite scanning device operates in three visible and three thermal channels. This allows you to record small fires on Earth, assess the state of the ice cover in the ocean, observe the dynamics of winds and solve many other applied tasks important for predicting global weather. The shooting equipment of the new Meteor implements a remote focusing function that adjusts the shooting parameters depending on the surrounding conditions of space - thermal and radiation effects on satellite instruments, said the chief designer of the RKS direction Yuri GROVIN.

The primary radiometric and geometric processing of images is carried out directly in the LCS using its own computational means and algorithms laid down on Earth. The received digital stream is combined with the target information from the heliogeophysical equipment complex and supplied to ground reception points, where the information is processed and then transmitted to consumers. All satellite systems involved in data transmission and processing were developed and manufactured in the Russian Space Systems holding.

The updated Meteor is also equipped with a command and measurement system (CIS) created in the RKS to control the satellite and an on-board information telemetry system (BITS) to collect information about its current state. The holding's specialists also manufactured an on-board information system with a meter range radio link and a data collection and transmission system. The spacecraft also includes a rescue radio complex created in the RKS holding, which will be used to receive and relay signals from emergency radio beams of the international COSPAS-SARSAT system.

Information support for the launch of a launch vehicle with a satellite was provided by a ground command and measurement point on Vostochny (VKIP), created by the Russian Space Systems. To receive information at the initial stage of the flight of the upper stage, a mobile measuring point developed in the holding, deployed and deployed near the Norilsk airport, was also used.

With the launch of this satellite, the Russian orbital constellation of DZZ satellites, in addition to satellites of other types, now includes, in particular, three Meteor series devices. The satellites successfully monitor climate and environment, natural and man-made emergencies, transmit signals from the COSPAS-SARSAT global search and rescue system. During their operation, the reliability of the onboard equipment for the development and production of the Russian Space Systems was confirmed.

2021: Development of workplaces for accelerated tests of CIS satellites of the Meteor-M series

On September 9, 2021, the company Russian space systems"" (RKS, part of the State Corporation Roskosmos"") announced that its specialists had developed modernized workplaces for accelerated tests of command and measuring systems of space the apparatus. According to RSK estimates, the unified test equipment will significantly reduce the time for creating the Russian satellites remote sensing Lands of the Meteor-M series for ecological monitoring.

The Meteor-M on-board command and measurement system (CIS), which will be tested using the created workplaces, is service devices for transmitting telemetry data, receiving control commands and measuring orbit parameters. The CIS maintains communication with the Earth, collects and transmits telemetric information to ground control points, and also processes control commands coming from the Earth and monitors their execution. The CIS monitors the correct operation of the orientation system and telecommunications systems of the satellite. It is used to measure the current navigation parameters of the spacecraft.

The upgraded PKS workstation is a compact device with a traditional home computer system unit with a dozen connectors, I/O boards, telemetry and a switching board. Part of connectors It is connected to the command and telemetry information decoder - one of the main command and measuring lines in the onboard equipment. Oscilloscopes, power supplies, voltmeters and other "mounted" measuring equipment are connected to the remaining connectors.

Previously, a workstation with its own measuring simulator boards and a set of measuring equipment was manufactured for each decoder of command and telemetric information. Now a single emulator board is installed at the output, which is unchanged from device to device and will test two decoders at the same time. Thus, the costs and time for testing onboard systems are significantly reduced, which in turn makes it possible to speed up the process of manufacturing modern Russian satellites.

"Using the device, the flight set of the on-board command and measurement line of the Meteor-M satellite No. 2-3 will be assembled. We plan to extend the technical principles laid down in this device to the entire subsequent practice of creating onboard equipment. Our development is another step towards the unification of the production of equipment for satellites, "- says Alexander Pushkin, head of the RKS onboard device workplace development group.

RKS creates on-board command and measurement equipment, with the help of which stable control of spacecraft and transmission of telemetric information to Earth are provided. The development and improvement of onboard service devices and test equipment has been going on for more than a dozen years, which makes it possible to create solutions with a large margin of reliability that have passed flight qualifications on a number of Earth remote sensing satellites.
