Minimize PRARE
Instrument image

The Precise Range And Range-Rate Equipment PRARE is a compact, space-borne, two-way, two-frequency microwave satellite tracking system that is in routine operations onboard the second European Remote Sensing satellite ERS-2 since May 1st, 1995. With the assistance of a global network of mobile, unattended, autonomously operating ground stations, the system performs synchronous two-way pn-coded range (= slant distance) and carrier shifted range-rate (= relative velocity) measurements at a sub-decimeter resp. sub-millimeter/second level of accuracy.
