Session: Precision Orbit Determination

Presentation type: Type Poster

The Copernicus Precise Orbit Determination (CPOD) Service delivers, as part of the Ground Segment of the Copernicus Sentinel-1, -2, -3, and -6 missions, orbital products and auxiliary data files for their use in the corresponding Payload Data Ground Segment (PDGS) processing chains at ESA and Eumetsat and to external users through the ESA Copernicus Open Access Hub.
In this contribution focus is given to the altimeter satellites Sentinel-3A, -3B, and Sentinel-6 Michael Freilich for which the CPOD Service is responsible for near real-time orbit products. Contrary to the Jason-1,-2, and -3 satellites, the GNSS POD NRT orbits (ROE) computed by the CPOD Service are used and DORIS DIODE aboard is the backup. For the Sentinel-3 satellites also a short-time critical and non-time critical orbit product is delivered as backup to the CNES (Centre National d’Etudes Spatiales) orbit products.
The CPOD Service is supported by the CPOD Quality Working Group (QWG), composed by leading experts on GNSS and Low Earth Orbit (LEO) POD. Independent orbit solutions are provided from these members to support quarterly and yearly Regular Service Reviews. These reviews guarantee a continuous and independent quality control of the orbital products generated operationally by the CPOD Service. In addition, the CPOD QWG regularly meets to discuss recent developments and enhancements in the field of LEO POD and the applicability to the service operations.
In the frame of the Regular Service Reviews non-time critical orbits from the three altimeter satellites are compared to CNES and other orbit solutions from members of the Copernicus POD Quality Working Group (QWG). Satellite Laser Ranging measurements are used to independently validate the orbits.
Overview and status of the Copernicus POD Service is presented in terms of organisation, design, operations and performance in particular related to Sentinel-3 and Sentinel-6 satellites.
