ERS-1/2 Precise Orbit Product
Entry ID: ERS.ORB.PRC

[ Update this Record ]

Summary
Abstract: The precise orbit results from a data reduction
process in which all available tracking data (SLR, radar
altimeter crossovers, PRARE range and doppler data) and
most accurate correction, transformation and dynamical
models are taken into account and in which high level
numerical procedures are applied.




These orbits are "optimal" achievable
representations of the real orbital motion under the

Quality The quality of the generated orbits is controlled
formally and internally. The formal quality
control includes procedures to check
the correct format and to flag periods where the
orbit is degraded by manoeuvres or platform anomalies.


Internal quality checks are performed by:
- examining the fits of the laser ranges and the
altimeter ... View entire text
