| Content: | ******************************************************************************** SLR Electronic Mail 1997-07-01 14:00:00 UTC Message No. 70 ******************************************************************************** Author: Roger Wood, SLR Herstmonceux Subject: Standard TBFs - end of trial period This note announces the beginning of full operational distribution of Standard Time Bias Functions (TBFs) and the end of the trial period. The main consequence for observing stations will be that, from 1997 July 15, TBFs will be distributed only in the standard format: all other distribution formats will be discontinued. Stations which have not yet done so are urged to make the simple format changes to enable them to process standard format TBFs. Any stations experiencing difficulty with this timescale should contact TBF providers direct to request special treatment. All providers of TBFs are urged to cast them in the standard format and send them to the clearing house (slr@gxvf.rgo.ac.uk) for daily, global distribution via the European Data Centre. The intention (networks permitting) is to email a file of the latest TBFs to the global community at about 1600 UT each day. Additional mailings may also be made at any time if there are significant changes in the TBFs of ”difficult” satellites like GFZ-1. Every mailed file will contain the TBFs of all current satellites, updated to include any TB data available since the last mailing. Each mailed file will also be deposited in the EDC and RGO Cambridge databases for retrieval via anonymous FTP. ======================================================================= Roger Wood, NERC Satellite Laser Ranger Facility, Herstmonceux Castle Hailsham, East Sussex, UK BN27 1RP Tel: +44 (01323) 833888 Fax: +44 (01323) 833929 Email: rw@gxvf.rgo.ac.uk ======================================================================= From: slr@gxvf.rgo.ac.uk (SLR at Herstmonceux) ******************************************************************************** |
