Instrument Information
IDENTIFIER urn:nasa:pds:context:instrument:rss.mer2::1.1
NAME RADIO SCIENCE SUBSYSTEM
TYPE ATMOSPHERIC SCIENCES
DESCRIPTION The Mars Exploration Rover (MER) mission includes two spacecraft, Spirit (MER-2) and Opportunity (MER-1). The MER Radio Science data consist of measurements of the Doppler shift of the rover radio signal as measured by the NASA Deep Space Network (DSN) and by the Mars Odyssey orbiter (ODY). The primary purpose of all equipment was collection of telemetry from the rovers, with Doppler measurements made for rover position determination as required and on a best efforts basis to support Radio Science. The performance and calibration of both the spacecraft and tracking stations directly affected the radio science data accuracy, and they played a major role in determining the quality of the results. The MER part of the radio science instrument is described immediately below; that is followed by a description of the relevant ODY relay radio system and a description of the DSN (ground) part of the instrument.
