Using quaternions in DORIS data processing
Abstract
The paper investigates the use of quaternions in processing DORIS measurements of RINEX format and evaluates the impact of using quaternions on the accuracy of processing results. Data processing using quaternions was used for measurements of the Jason2 and Jason3 satellites. For the Jason2 project, the processing interval was 2008.5–2019.8, for the Jason3 project — 2016.0–2023.0. The results of the radial velocity calculation between the transmitters and receivers of these missions show a slight decrease in the average residual radial velocity error when using quaternions (less than 1 percent). Thus, with the DORIS measurement processing strategy used, the use of quaternions does not significantly affect on the accuracy of the resulting solution.
