A New Generation of Intelligent Mapping and Remote Sensing Scientific Test Satellite Luojia-3 01
Abstract
With the continuous improvement of the performance and the increasing variety of optical mapping and remote sensing satellites, they have become an important support for obtaining global accurate surveying and mapping remote sensing information. At present, optical mapping and remote sensing satellites already have sub-meter spatial resolution capabilities, but there is a serious lag problem in mapping and remote sensing information services. It is urgent to develop intelligent mapping and remote sensing satellites to promote the transformation and upgrading to real-time intelligent services. Firstly, based on the three imaging systems of the optical mapping and remote sensing satellites and their realization methods and application characteristics, this paper analyzes the applicable system of the intelligent mapping and remote sensing satellites. Further, according to the application requirements of real-time, intelligence, and popularization, puts forward the design concept of integrated intelligent remote sensing satellite integrating communication, navigation, and remote sensing and focuses on the service mode and integrated function composition of intelligent remote sensing satellite. Then expounds on the performance and characteristics of the Luojia-3 01 satellite, a new generation of intelligent surveying and mapping remote sensing scientific test satellite. And finally summarizes and prospects the development and mission of intelligent mapping remote sensing satellites. Luojia-3 01 satellite integrates remote sensing and communication functions. It explores an efficient and intelligent service mode of mapping and remote sensing information from data acquisition to the application terminal and provides a real service verification platform for on-orbit processing and real-time transmission of remote sensing data based on space-ground internet, which is of great significance to the construction of China’s spatial information network.
