Abstract

This paper presents results of the DORIS global network data processing for the ITRF2014 carried out at the DORIS Analysis Center (AC) of the Institute of Astronomy of the Russian Academy of Sciences (INASAN), named as INA. INA DORIS AC reprocessed all DORIS data for the time period from 1993.0 to 2015.0 (22 years). The evaluated SINEX free-network (inawd08) weekly solutions for station positions and polar motion have been submitted to the IDS Combination Center for validation. GIPSY-OASIS software (version 6.2) developed by JPL has been used for processing. As compared to the previous INA DORIS ITRF2008 (inawd07) contribution several new models are included in GIPSY-OASIS II software for ITRF2014 computations. The data of majority DORIS satellites are processed, except for HY2A, SARAL and JASON1. The corrected data of SPOT5 SAA (South Atlantic Anomaly) have been used for processing from the beginning of 2006.0 onward. Unlike from the other Analysis Centers, INA AC hasn't applied phase center law for ground antennas. Preliminary analysis of inawd08 weekly solutions, made by the IDS Combination Center, showed an improvement as compared to the inawd07 ones. The effect of application of the phase center variation (PCV) correction model for ground antennas on DORIS-derived Terrestrial Reference scale was investigated. It is shown that the effect of PCV correction model application for ground-based DORIS antennas offsets the mean scale factor for about 1.24 ppb (~ 10 mm) with respect to processing without PCV correction.

processing for the ITRF2014 carried out at the DORIS Analysis Center
(AC) of the Institute of Astronomy of the Russian Academy of Sciences
(INASAN), named as INA. INA DORIS AC reprocessed all DORIS data for
the time period from 1993.0 to 2015.0 (22 years). The evaluated SINEX
free-network (inawd08) weekly solutions for station positions and
polar motion have been submitted to the IDS Combination Center for
validation. GIPSY-OASIS software (version 6.2) developed by JPL has
been used for processing. As compared to the previous INA DORIS
ITRF2008 (inawd07) contribution several new models are included in
GIPSY-OASIS II software for ITRF2014 computations. The data of
majority DORIS satellites are processed, except for HY2A, SARAL and
JASON1. The corrected data of SPOT5 SAA (South Atlantic Anomaly) have
been used for processing from the beginning of 2006.0 onward. Unlike
from the other Analysis Centers, INA AC hasn't applied phase center
law for ground antennas. Preliminary analysis of inawd08 weekly
solutions, made by the IDS Combination Center, showed an improvement
as compared to the inawd07 ones. The effect of application of the
phase center variation (PCV) correction model for ground antennas on
DORIS-derived Terrestrial Reference scale was investigated. It is
shown that the effect of PCV correction model application for ground-
based DORIS antennas offsets the mean scale factor for about 1.24 ppb
(~ 10 mm) with respect to processing without PCV correction.
