B.; Buisson, J. A.; Reid, W. G. Abstract: An on-orbit frequency stability performance analysis of the GPS NAVSTAR-1 quartz clock and the NAVSTARs-6 and -8 rubidium clocks is presented. The clock offsets were obtained from measurements taken at the GPS monitor ... NASA Center: NASA (non Center Specific) Publication Year: 1984 Added to NTRS: 2006-08-02 Accession Number: 85N29227; Document ID: 19850020915 Submicrosecond comparisons of time standards via the Navigation Technology Satellites (NTS) Author(s): Buisson, J. A.; Mccaskill, T.; Oaks, J.; Lynch, D.; Wardrip, S. C.; Whitworth, G. Abstract: An interim demonstration was performed of the time transfer capability of the NAVSTAR GPS system using a single NTS satellite. Measurements of time difference (pseudo-range) are made from the NTS tracking network and at the ...

C.; Buisson, J. A.; Oaks, O. J.; Lister, M. J.; Detoma, E.; Dachel, P.; Stalder, T.; Warren, H.; Winkler, G. M. R.; Luther, G. Abstract: The overall experiment was designed to test the positioning and navigation capabilities of the GPS timing receivers developed by the Naval Research Laboratory (NRL) for the NASA Goddard Laser Tracking Network (GITN). To ... NASA Center: Goddard Space Flight Center Publication Year: 1985 Added to NTRS: 2004-11-03 Accession Number: 85N28303; Document ID: 19850019991 Prototype design and initial test evaluation of a Global Positioning System Time Transfer Receiver (GPS TTR) Author(s): Oaks, O. J., Jr.; Frank, A. H.; Falvey, S. R.; Lister, M. J.; Buisson, J. A.; Wardrip, S. C.; Warren, H. F. Abstract: Time-transfer equipment and techniques used with the NRL Navigation Technology Satellites have been modified and extended for use with the GPS satellites. A prototype receiver was built and field tested at NASA's Kennedy ...
