Data was therefore collected at an interval of 20 sec. This data has not been uploaded to the IGS Global Data Archive at CDDIS but is available on request. A replacement Ashtech micro-Z receiver was installed at SACH at approximately 18:00 UT on DOY 045. It uses new firmware that fixes the underlying memory problem with the old firmware. Operations are now back on line and data since DOY 046 has been uploaded to CDDIS. The 6 hour data file for DOY 045 will also be uploaded later today and an updated site log sent to the IGS. We apologize for any inconvenience. -- Mike Craymer, Ph.D. Geodetic Survey Division, Natural Resources Canada 615 Booth Street, Ottawa, Ontario K1A 0E9, Canada Tel 613-947-1829, Fax 613-992-6628, Cell 613-791-0157 Email Geodetic Survey Division NAREF
