****************************************************************************** dorismail 26-Mar-2012 09:15:52 Message No 0805 ****************************************************************************** Author: Ferrage Pascale Subject: different ID for Master Beacons Dear Colleagues, As announced in DORISmail No 802: "site logs updated + local ties file", the DORIS sitelogs have been updated on the IDS website at http://ids-doris.org/network/sitelogs.html We would like to make a few clarifications regarding the 4-character identification code (ID) of the Master Beacons (MBs). Except for the MBs, the DOMES number of a DORIS station is always associated to a single ID. When the antenna is changed or moved, a new reference point is defined and a new DOMES number and a new ID are given, even if the tie with respect to the previous reference point is null. When the beacon is changed, DOMES number and ID are not changed. For the MBs (Kourou, Toulouse, Hartebeesthoek and Papeete), it occurred that IDs were changed but the DOMES number was kept unchanged. These are the following cases for which one DOMES number is associated to two different IDs. Kourou: 2 IDs, KRUB and KRVB, but 1 single DOMES number 97301S004 Toulouse: 2 IDs, TLHA and TLIA, but 1 single DOMES number 10003S003 Hartebeesthoek: 2 IDs, HBKB and HBLB, but 1 single DOMES number 30302S006 (see also DORISmail No 474 ftp://ftp.ids-doris.org/pub/ids/dorismail/dorismail.0474 ) Papeete: 2 IDs, PATB and PAUB, but 1 single DOMES number 92201S010 (see also DORISmail No 632 ftp://ftp.ids-doris.org/pub/ids/dorismail/dorismail.0632 ) The IDs were changed either when the nominal MB was switched to the redundant MB or vice versa (Kourou, Toulouse) or when the standard orbit determination beacon was upgraded to a MB (Hartebeesthoek, Papeete). The DOMES number was not changed because there was no physical change on the antenna.
