Subject: [SLR-Mail] No. 35: Recall of SLR Data from GPS Satellites From: Carey Noll/CDDIS and Van Husson/ATSC <[Mailed Carey Noll 301-286-9283 ]> ******************************************************************************** SLR Electronic Mail 1996-12-10 01:00:00 UTC Message No. 35 ******************************************************************************** Author: Carey Noll/CDDIS and Van Husson/ATSC Subject: Recall of SLR Data from GPS Satellites Van Husson of AlliedSignal Technical Services (ATSC) reports that a number of SLR normal point pass segments from the NASA SLR network for the GPS satellites potentially contain no useful data (i.e., all noise) and are being recalled from the CDDIS to avoid the future use of these known problem data. The data in all of these recalled passes, listed in Table 2 below, are currently under evaluation for the possibility of useful data. If any data are found in these pass segments, normal points will be reissued at a later date. Furthermore, as of December 06, 1996, new procedures have been implemented at ATSC to prevent SLR data with known problems from being distributed to the user community. The ATSC and CDDIS staff regret any inconvenience these data problems may have caused the user community. GPS-35 and -36 SLR Data Recalled Num. of Satellite Date Time Station Npts.
