Abstract:The LT4A satellite is the world's first IGSO satellite capable of receiving GPS and BDS signals. It is also the world's first SAR satellite in high orbit. Based on the received GNSS data, the data availability and measurement quality were first analyzed, and then the accuracy of the 30-h and 72-h arc length orbit determination results were verified using the orbit overlap method and the laser ranging verification method. According to the data analysis, the onboard receiver of the LT4A satellite can receive an … Show more
