The RESURS-P Earth Observation Space System In-Flight Tests Are Over. / October 2, 2013 /

On 30 September at ROSCOSMOS the State Commission meeting on in-flight tests of socio-economic, scientific and commercial space systems was held which considered the in-flight testing results the RESURS-P space system with the RESURS-P1 satellite.
Based on the in-flight testing results obtained, there was made the decision on the RESURS-P space system/RESURS-P1 satellite compliance with the performance specification requirements and the possibility of the system putting into normal operation since 1 October 2013.

The RESURS-P space system is for high-detailed, detailed wide-swath and hyperspectral optoelectronic observation of the Earth’s surface. (The RESURS-P satellite images).
The RESURS-P1 satellite was launched on 25 June 2013 from the Baikonur Cosmodrome.
The RESURS-P spacecraft is manufactured by GNPRKTs TsKB-Progress based on the existing backlog and project developments to improve its performance targets in the following key areas: increase in the number of narrow spectral bands from 3 to 5, hyperspectral and stereo imaging, 10-15m accuracy geolocation of images with no use of ground control points, increase in spacecraft active lifetime from 3 to 5 years. The high-precision control system enables both along-track (StripMap) and at-an-angle-to-track acquisition modes. The equipment installed is capable of stereo imaging and imaging of areas in the same orbit.
The spacecraft is the second in the RESURS series satellites in the domestic constellation of civil remote sensing with very high resolution and is designed for information support of the Earth observation applications:
— Compiling and updating the general geographical, thematic and topographic maps;
— Monitoring of the environmental pollution and degradation;
— Inventory of natural resources and business process monitoring to ensure an effcient activity in various sectors of the economy;
— Information support for exploration of oil, natural gas, ore and other minerals;
— Monitoring of territory building, acquisition of data for engineering evaluation of terrain to the benefit of economical activity;
— Monitoring of water protection and reserved areas;
— Ice conditions assessment;
— Monitoring of emergencies for prevention, warning mitigation and relief of natural disasters, accidents, and catastrophes and for effects assessment to plan proper reconstruction actions.
RESURS-P is a spacecraft with radically new capabilities including first of all its special-purpose equipment. One of the basic principles of the RESURS-P space system formation is the use of technical solutions accumulated in creating the RESURS-DK spacecraft. The RESURS-DK capabilities were considerably improved in the swath width and panchromatic and spectral resolution level. The spacecraft operates in near-circular sun-synchronous orbit enabling the observation conditions to be improved more significantly than those of the RESURS-DK. The new spacecraft is capable of imaging at the same altitude and under the same lightning conditions. The revisit time is reduced from six to three days. Besides, the consumer properties and geolocation accuracy of images transmitted, and the spacecraft dynamic characteristics were improved.
The build-up of the new spacecraft performance characteristics is provided by several types of imaging equipment. The RESURS-P spacecraft is equipped with optoelectronic payload allowing the acquisition of high-detailed images of 1m resolution at 475km altitude in panchromatic band, and in narrow spectral bands with no less than 3-4m resolution.
Two more types of imaging equipment were included in the RESURS-P instrument payload: hyperspectral imaging equipment – GSA (developed by JSC KMZ) and a wide-angle multispectral imaging equipment – KShMSA (developed by TsSKB-Progress — NPP OPTEKS). The GSA swath with is 25km, resolution is about 25m. The KShMSA equipment provides a detailed wide-swath observation with 12m resolution in swath width of the order of 100km, and with 60m resolution in the 440km swath width. In combination with panchromatic images, a simultaneous imaging in fixed spectral bands is provided.
This equipment will increase the list and quality of problems solved by the spacecraft to the benefit of socio-economic development of the country and its regions.
