SINEX file format
This section contains links to the definitions of various sinex formats.
Please note that the draft version of SINEX 2.02 was initially labeled 2.10.
It was subsequently renamed to 2.02. This should not be confused with Calc/Solve SINEX V2.10 as the meaning of the nutation parameters are different.
- SINEX 2.01 nutation parameters are total nutation angles.
- SINEX 2.02 nutation parameters are with respect to the apriori angle.
- SINEX 2.10 (calc/solve) nutation parameters are total nutation angles.
- template of mandatory description for SINEX submissions (courtesy of Axel Nothnagel)
