Abstract: A portable ground test platform based on USB2.0 interface including PC software and a USB communication adapter is designed to simulate data communications between satellite platform and satellite-borne spectrometer. The upper computer software offers a human-computer interaction interface. The adapter complete communications between low voltage differential signal (LVDS) data including image transfer data and manage data of satellite-borne spectrometer and USB interface. Experimental results indicate that the designed platform can convert the LVDS image data of spectrometer to USB interface data, and simulate the satellite platform data. It can be used for spectrometer debugging and test. The measured rate of communication adapter’s USB2.0 interface can reach 230 Mbps, and it can be used as a module to interface commercial spectrometer.
