Subject: [SLR-Mail] No. 1167: 7105 GODL Calibration RMS Increase From: Van S.

Husson, ILRS CB Subject: 7105 GODL Calibration RMS Increase Dear Colleagues, The Greenbelt station (7105) had a failure of it´s HP 5370B counter in early December. Attempts to repair it failed. A replacement counter was installed between December 9 and 10, 2003. Post counter replacement, the calibration RMS´s have increased from 4-5 mm to 12-15 mm. Corresponding satellite RMS´s have increased about 30 to 50%. Hopefully the increase in RMS´s are due to random errors and not systematic errors in the replacement HP 5370B. But Analysts be on alert.
