Resource-P (space satellites)

2024

Continuity

High-tech onboard equipment developed by the Russian Space Systems holding (part of the Roscosmos State Corporation) ensures the continuous operation of the Resource-P remote sensing satellite (DZZ) No. 4, launched in March 2024. The spacecraft was successfully commissioned as part of the Russian orbital group DZZ; the operator of "Resource-P" No. 4 is the Scientific Center for Operational Monitoring of the Earth RKS. This was reported to the RKS on June 19, 2024.

All devices created by RKS specialists operate normally and perform functions in full. Most of the targeted optical and electronic equipment "Resource-P" are devices created by the Scientific and Production Center "OPTEX," which became part of JSC "Russian Space Systems" in 2023.

The key of the OPTEX devices is the Sangur-1U information reception and conversion system, which is part of the Geoton-L1 high-resolution main camera equipment. It allows highly detailed shooting of the earth's surface with a resolution of 0.7 meters in the panchromatic range and multispectral shooting with a resolution of 2.1 m in six narrow subbands at the same time. The width of the strip removed in one span is 38.6 km. During shooting "Sangur-1U" converts continuously moving image of visible range formed by optical-electronic complex into digital electric signal, processes it, compresses it and transmits it to aircraft equipment of high-speed radio link.

An equally important component of the satellite's target equipment is a complex of wide-range multispectral equipment, consisting of two high-resolution cameras that transmit space survey data in 6 spectral bands at once in the capture band up to 180 km with a resolution of 12 meters in black and white shooting and 24 meters in color.

The hyperspectral shooting equipment "Resurs-P" No. 4 also uses an image reception and conversion system. It is based on photodetector devices created by OPTEX specialists based on high-speed specialized personnel matrices of the visible and near infrared range, as well as equipment for controlling and ensuring the temperature regime of the shooting equipment as a whole. The system can capture simultaneously in the 96-216 spectral channels.

Control of all modes of operation of the main optical-electronic equipment, including focusing, calibration and change of light filters, is carried out by the SU-165 control system, also developed by OPTEX specialists.

The spacecraft of the Resource-P series is the flagship of the domestic orbital group DZZ. When creating the target equipment of the new Resource-P, specialists of RCC Progress JSC and RKS used innovative fiber-optic high-speed information transmission lines. This technology has provided us with an important quality - the opportunity to improve the quality of shooting and the volume of transmitted and processed data while reducing the total mass, to create a high-performance popular device with a special set of ultra-high-resolution equipment in combination with multispectral wide-grip and hyperspectral cameras. In addition, with the launch of Resurs-P No. 4, the technology of introducing a new spacecraft into the orbital group without significant refinement and, moreover, without creating a separate ground-based complex for receiving, processing and disseminating information has been developed - these functions are implemented on the basis of the Operator of the space system DZZ of the Unified Geographically Distributed Information System (ETRIS DZZ). " said Andrey EMELYANOV, Director of Projects for the Creation of DZZ Systems, Deputy General Designer of RKS.

The service equipment "Resurs-P" No. 4 is represented by the onboard information and telemetry system BITS2Ts-7M - the own development of the RKS. Its main function is to accumulate, convert, store and transmit information on the state of onboard complexes, instruments and structural elements of the satellite via the radio communication channel to ground stations.

Three more important complexes - a ground control system, onboard equipment of a command and measuring system and a high-speed radio line - were developed by specialists from the Research Institute of Precision Instruments (NII TP, part of the RKS holding).

When upgrading the hardware and software of the Resource-P spacecraft No. 4, we relied on the need to solve the main problems: unification of equipment, manufacturability, reliability, use of a modern element base, preservation and improvement of tactical and technical characteristics. Together with new technologies, design and test methods, this gave us the opportunity to provide truly unique target parameters of the satellite and the space system as a whole, to create a fundamental groundwork for the creation of promising airborne and ground complexes, noted Chief Designer - Deputy General Director of JSC "NII TP" Gleb GOLUBIN.

The Resource-P ground-based space system control complex was created using virtualization and scaling technologies. It allows satellites to be controlled from "virtual" flight control centers, ensuring the continuity of technology for both existing and new types of spacecraft on already created computing power without their refinement.

Built on high-tech solutions and modern components, the onboard equipment of the spacecraft command and measurement system independently controls the satellite without interruptions in communication sessions even with unstable orientation and its rotation.

The upgraded on-board equipment of the high-speed radio link operates in the same frequency range from 8.0-8.4 MHz, but with a doubling of the information transfer rate to 600 Mbps, it has increased reliability and expanded functionality.

Production of space equipment for recognizing objects from 70 cm at a distance of 475 km from the surface of the Earth has begun

At the end of March 2024, the space remote sensing satellite Lands "" No. Resource-P 4 was launched into orbit, which is equipped with optical and electronic equipment "Geoton-L1," which allows you to create accurate maps of the area and identify places of emergency. The equipment is developed and manufactured by specialists Krasnogorsk Zverev Plant (KMZ, part of the state corporation holding SchwabeRostec). More. here

Launch of a new Resource-P satellite into orbit

On March 31, 2024, Roscosmos launched a new space satellite Resource-P into orbit. The missile was launched from the Baikonur cosmodrome.

The launch of the Soyuz-2.1b launch vehicle took place on March 31, 2024 at 12:36 Moscow time. According to the press service of Roscosmos, the launch of the satellite into a given orbit took place normally. The state corporation noted that for Soyuz-2.1b this flight was the 70th in history. This is the fifth launch of the Russian launch vehicle in 2024, including the third from the Baikonur cosmodrome.

Resurs-P is a group of Russian civil spacecraft for remote sensing of the Earth (DZZ). The images obtained by them are used in drawing up and editing maps and in environmental control measures and in finding potential places of oil and other useful ones. minerals In addition, when studying satellite images in various spectral ranges, it is possible to determine the maturity of cereals in the fields, the biological purity of water bodies and the level of soil salinity.

The "Resource-P" devices are designed to update maps, support economic activities, Ministry of Natural Resources of Russia,, and MINISTRY OF EMERGENCY SITUATIONS Russia Rosrybolovstvo Roshydromet other consumers. The Resource-P satellites are being developed by the Progres Rocket and Space Center. The design service life of the Resurs-P spacecraft is 5 years.

The further development of these high-detail survey satellites is associated with the development of the Resource-PM satellite with improved characteristics. Roscosmos notes that the Resource-P satellites, together with ground-based information receiving points, form a single integrated surveillance system. Due to the deep integration of technologies implemented during the creation of the space complex, the capabilities of the system are significantly higher than the capabilities of three autonomously operating devices, the state corporation emphasized.^[1]
