Transactions of IAA RAS, issue 43, 85–94 (2017)

Keywords: geocenter motion, GNSS, DORIS, SLR, time series of the geocenter motion

Abstract

This article presents the geocenter motion obtained in the Institute of Astronomy, Russian Academy of Sciences (INASAN) as a result of processing measurements made by various space geodesy techniques (GNSS, DORIS and SLR). GNSS data were processed for the time period from 2008 to 2016 using measurements from 54 stations of the IGS network equipped by the dual-system GPS+GLONASS receivers. PPP method was used for the GNSS data processing. DORIS data were processed for the time interval from 1993 to 2017 for all working IDS stations. SLR measurements from 2 high-orbit LAGEOS-1/LAGEOS-2 satellites and 3 low-orbit Stella/Starlette/AJISAI satellites were processed for the time period from 1993 to 2015 using data from all stations of the SLR network. Time series of the geocenter motion were derived from the GNSS and DORIS data using a geometrical method (so-called “network shift approach”), while an estimation of the first degree coefficient of the Earth gravity field was used for the SLR data. Amplitudes, periods and phases of the geocenter variations were estimated using the software FAMOUS (CNES, France). Amplitudes and phases of annual geocenter variations derived in the INASAN from the satellite method are in a good agreement with those obtained by other space geodesy groups and geophysical models. All time series of the geocenter motion are expressed in ITRF2008.

of Astronomy, Russian Academy of Sciences (INASAN) as a result of
processing measurements made by various space geodesy techniques
(GNSS, DORIS and SLR). GNSS data were processed for the time period
from 2008 to 2016 using measurements from 54 stations of the IGS
network equipped by the dual-system GPS+GLONASS receivers. PPP method
was used for the GNSS data processing. DORIS data were processed for
the time interval from 1993 to 2017 for all working IDS stations. SLR
measurements from 2 high-orbit LAGEOS-1/LAGEOS-2 satellites and 3
low-orbit Stella/Starlette/AJISAI satellites were processed for the
time period from 1993 to 2015 using data from all stations of the SLR
network. Time series of the geocenter motion were derived from the
GNSS and DORIS data using a geometrical method (so-called “network
shift approach”), while an estimation of the first degree coefficient
of the Earth gravity field was used for the SLR data. Amplitudes,
periods and phases of the geocenter variations were estimated using
the software FAMOUS (CNES, France). Amplitudes and phases of annual
geocenter variations derived in the INASAN from the satellite method
are in a good agreement with those obtained by other space geodesy
groups and geophysical models. All time series of the geocenter
motion are expressed in ITRF2008.
