Envisat DORIS Precise Orbit State Vectors [DOR.VOR_AX]
Listed in NASA Earthdata CMR
The latest version of the Envisat DORIS Precise Orbit product (DOR_VOR_AX) was generated by the Centre de Traitement Doris Poseidon (CTDP) using the Geophysical Data Records F standards (GDR-F).
Description
The product is used to obtain the satellite orbital parameters (latitude, longitude, height and height rate) by using orbit computation routines. The most significant changes related to the GDR-F standards concern the new ocean tide model (FES2014) and the updated Terrestrial Reference Frame (ITRF2014).
The new standards significantly improve all Precise Orbit Determination (POD) metrics with respect to GDR-E: the mean difference and variance of Sea Surface Height (SSH) at crossovers is slightly reduced. The DOR_VOR_AX product adopts the Envisat format, and the size is 0.2 Mbytes per orbit. Users are recommended to apply the GDR-F version, but the previous datasets are still available (i.e. GDR-D and GDR-E versions).
