The reporter learned from China Siwei Surveying and Mapping Technology Co., Ltd. (hereinafter referred to as "China Siwei") that on March 16th at 2:00, the ground receiving station of the Kashgar satellite successfully received the first batch of satellite image data transmitted by the "Siwei Gaojing-3" 02 satellite. This image has a super wide range of 130 kilometers and a resolution of 0.5 meters. The image is clear, with distinct layers, rich details, full colors, uniform image quality, and good radiation consistency. It is reported that as the sister star of "Four Dimensional Gaojing-3" 01, the "Four Dimensional Gaojing-3" 02 satellite combines the characteristics of ultra wide swath imaging technology and deep integration of multi spectral observation capabilities. By successfully completing the network operation of 02 and 01 satellites, the two wide swath optical satellites will form a more efficient and reliable collaborative system, and the data acquisition capability will be greatly improved. The innovation of "Four Dimensional Gaojing-3" 02 satellite adopts high-density compressed storage technology, on-board autonomous intelligence technology, high-speed high-order phased array transmission technology, high-performance multispectral integrated detector technology, high-precision uncontrolled positioning technology, etc. It combines the characteristics of intelligence, flexibility, superior performance, and intensive reliability. Its technical indicators have reached the leading domestic and international advanced level among commercial remote sensing satellites. The satellite is equipped with 9 imaging bands. In addition to the common panchromatic, red, green, blue, and near-infrared bands, 4 new bands including coastal aerosol, yellow, red edge, and near-infrared have been added, which can serve various quantitative application scenarios such as forest classification, vegetation monitoring, crop yield estimation, land resources investigation, and marine environmental protection. In addition, satellites have the ability to independently and quickly process images on board, and achieve satellite intelligence empowerment through the use of on-board task planning, intelligent target detection and recognition, greatly improving satellite operation capabilities and service timeliness. The "Four Dimensional Gaojing-3" 02 satellite was launched into space by the Long March 2D carrier rocket at 12:11 pm on March 15th. After the satellite entered orbit, it was in good condition and all subsystems started working normally one after another. At present, the operation of the sky earth link and ground system is stable, and the satellite has entered the in orbit testing phase. It is reported that China's Four Dimensional is building the "China Four Dimensional New Generation Commercial Remote Sensing Satellite System" with the goal of serving the market and commercial aerospace development needs. Its space segment plans to launch a total of 28 satellites, including 16 optical satellites with a resolution better than 0.5 meters, 4 wide swath optical satellites with a resolution of 0.5 meters, and 8 SAR satellites with a resolution better than 1 meter. It will also simultaneously construct a ground segment based on the "Four Dimensional Cloud" (including measurement and control, reception, processing, and application). According to market development, it can be expanded to 56 satellites in the future. The successful launch of the "Four Dimensional Gaojing-3" 02 satellite will achieve the operation of the "4+2+4" three type satellite network, marking a new stage of efficiency leap for the system.
