ERS PRARE Master Dataset Generation
ERS PRARE site 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. The ERS PRARE consolidation and master Dataset generation in SIP format Project has been started in December 2014 and is currently on-going, performed by the eXpert Product Reprocessing Scalable Service X-PReSS consortium under the ESA management.
