ADVISORY

The GPS tracker DRAO (Penticton, BC Canada) was shut down on DAY 125 from
17:08 UT until 18:44 UT to permit a software upgrade. New PROMS were
installed and a calibration carried out. The upgrade should solve the
problem of biases in pseudo ranges to certain SV's under A/S.

New calibration value is -7.679 nsec; (previous value -7.586 nsec);


Please address any questions to:
