[14 Mar 2011] a series of power outage expected from today due to the energy issues caused by the huge earthquake occurred on 11 March. This server will be occasionally shut down.
[03 Aug 2010] updated coordinates (based upon ILRS AWG discussion): 7405 (text file).
[17 Jul 2010] Analysis computer replaced due to a sudden failure of a 5-year old Epson NT9500Pro. New PC is a bit slower, Dell Inspiron 1526 (AMD Turion 64 TK-57 1.9GHz).

[13 May 2010] A special quicklook analysis on the coseismic displacement of Concepcion TIGO SLR station is placed here. Note that 2 to 3 metres biases of Concepcion (7405) is not due to their measurement error, but due to this 3.19-m displacement.
[13 Apr 2010] New statistics on "hit rate" of the ILRS Top-20 stations are available here.
[06 Jan 2010] Data server replaced. New machine: Dell Vostro 1220 with Ubuntu 9.10. CRD handling also implemented ahead of the ILRS conversion.

[14 Oct 2005] computer trouble. Switched to another PC (Dell Inspiron 8200).
[12 Oct 2005] corrected the centre-of-mass correction of GLONASS-95.
[27 Sep 2005] GLONASS-95 replaces GLONASS-84.
[9 Sep 2005] added: 7130 (ITRF2000 coordinates).
[30 Aug 2005] new coordinates (estimated from Aug data): 7358.
