In the motion simulation test, the real-time position and orientation of lunar rover need to be measured accurately in a wide area to test lunar rover’s motion performance on simulated lunar soil. The iGPS system, whose accuracy is better than 1mm and sampling frequency is higher than 10 Hz, is applied to measure the position and orientation of lunar rover in the test. Large-scale dynamic measurement of lunar rover with iGPS is studied in this paper. This paper mainly discusses the layout methods of laser transmitters and receiving sensors, and analyzes the position and orientation measurement accuracy of different layout methods to achieve optimization layout. It can provide some reference for the research of large-scale dynamic measurement of other rigid objects.
