CTOnews.com, 4 May, according to the news of China Aerospace Science and Technology Corporation on April 28, Tencent App Center, a resource satellite of China Aerospace Science and Technology Corporation, organized and held a review meeting on the "L-band differential interference SAR Satellite (Land Exploration-1 Satellite) ground system in orbit Test report" in Beijing.

The expert group listened to the report on the in-orbit test of the ground system of the Land Exploration-1 satellite, reviewed the relevant materials in detail, and agreed to pass the in-orbit test review of the ground system after questioning and discussion.

▲ Tupyuan China Aerospace Science and Technology Group Land Exploration No. 1 satellite is composed of two satellites, both of which are developed by the eighth Academy of Sciences (CTOnews.com Note: Shanghai Aerospace Technology Research Institute). They are scientific research satellites planned, deployed and built by the country's civil space infrastructure, including two L-band multi-polarization SAR satellites with the same performance indicators, mainly carrying out deformation monitoring and topographic mapping. This group of satellites will provide strong space technical support for geological disasters, land survey, earthquake assessment, disaster prevention and mitigation, basic surveying and mapping, forestry survey and other fields.

According to the China Aerospace Science and Technology Corporation, after the launch of the Land Exploration-1 satellite, the on-orbit test of the ground system has successively carried out various load parameters, geometric characteristics, radiation characteristics, polarization characteristics, ground system and other tests. a total of more than 80 satellite-to-ground integration tests and more than 30 ground system tests have been completed, many outfield calibration tests have been carried out, and the on-orbit test of the ground system integration index of the ground system has been successfully completed.

The test results show that all the indicators of satellite-ground integration meet the general requirements of development and construction, the functions of the ground system are normal, and the performance meets the engineering and technical indicators specified in the general requirements of development and construction and use requirements.

After the completion of the in-orbit test of the ground system of Land Exploration-1 satellite, it was transferred to the operation phase.
