Fagard" Subject: New station: Betio (Kiribati) Dear Colleagues, A new DORIS station has been installed in the premises of the Kiribati Meteorological Service station at Betio, Tarawa atoll, Republic of Kiribati. The DORIS equipment consists of a third generation beacon and a Starec antenna. The antenna is supported by a 1.5 meter high, 40 cm sided concrete pillar extending 2 m deep into the ground. Transmissions started on October 22, 2006, in the central frequencies mode. The name of the station is "Betio" and its acronym in the data files is BETB. The DOMES number for the antenna reference point is 50305S001. A permanent GPS receiver was installed in August 2002 by Geoscience Australia in the same premises, as part of the Continuous GPS Station Network deployed in the frame of the South Pacific Sea Level Climate Monitoring Program . Its antenna is located 18 m away from the DORIS antenna. The following coordinates for the DORIS antenna were derived from the connection to the GPS antenna, whose coordinates and velocities were kindly provided by Geoscience Australia. The resulting ITRF2000 @ 2000.50 coordinates are: X= -6327823.264 m Y= 785599.310 m Z= 149786.287 m SigX = 0.004 m SigY = 0.002 m SigZ = 0.002 m The velocities for this site, derived from the GPS time series, are : VX = 0.0065 m/y VY = 0.0689 m/y VZ = 0.0291 m/y SigVX = 0.0006 m/y SigVY = 0.0001 m/y SigVZ = 0.0001 m/y I wish to thank Geoscience Australia for their help in bringing this project to fruition, and for allowing us to put the DORIS equipment in the GPS concrete hut.
