Inter-satellite relative distance measurement device based on inter-satellite information exchange

An inter-satellite relative distance measurement device based on inter-satellite information exchange is disclosed, belonging to the field of aerospace application. The inventive aims at providing an inter-satellite information exchange-based inter-satellite relative distance measurement device which is simple in designed structure and capable of realizing relative navigation among a plurality ofsatellites. The invention uses an electric wire unit as a front end to accomplish the establishment of an inter-satellite link circuit with a field programmable gate array (FPGA) and a highly-integrated RF integrated nRF2401 RF chip; by means of the inter-satellite information exchange, the measurement of the inter-satellite relative distance is accomplished by utilizing time difference of recordinformation transmitted among satellites, therefore the inter-satellite relative distance relationship can be calculated. The device is used for the measurement of the inter-satellite relative distance.
