Full Name Doppler Orbitography and Radio-positioning Integrated by Satellite-New Generation XX Status Operational
Instrument Agencies CNES Maturity Medium Heritage
Instrument Type Precision orbit Geometry TBD
Instrument Technology Radio-positioning system Sampling Sounding
Data Access Data Format
Measurements and Applications Precise orbit determination; Real time onboard orbit determination (navigation). The main changes from previous versions of DORIS are the instrument will be fully redunded; software can be fully reloaded without any mission interruption; platform attitude is provided in real time to DORIS and used by Diode (on-board DORIS navigator), also downloaded by DORIS in the science telemetry flow; a dosimeter is included in the electronic box; the altimeter will received information from Doris onboard for real-time tracking
