Schmidt Subject: ALBH: Clock Change *************************************************************************** GEOLOGICAL SURVEY OF CANADA WESTERN CANADA DEFORMATION ARRAY GPS TRACKER ADVISORY GPS TRACKER ID: ALBH DOMES No.: 40129M003 CDP No. n/a MONUMENT No. 927000 LOCATION: Albert Head (Victoria, B.C.), Canada ADVISORY: We have had to remove the Cesium clock from the receiver at ALBH due to problems with the stability of the Cesium Clock. The receiver commenced operating on internal clock steering approx. 01:00UT D229. The receiver was also on internal clock steering commencing approx. 23:45 UT D269 until approx. 19:45UT D271 at which point the GPS receiver was reconnected to the Cesium Clock; unfortunately the frequency was not stable enough to permit continued operation in this mode and it has been disconnected. An updated log has been submitted to the IGSCB. Our apologies for this change.
