The Use of Gps Carrier Phase for Time Transfer
In the international timing community the use of the Global Positioning System (GPS) common view technique is well established and generally accepted as a means of high accuracy time transfer. The best results obtained with common view time transfer (using all available corrections) on long baselines (in the order of a few thousand kilometers) are a few (3
متن کاملGPS Measurements Anomaly and Continuous GPS Carrier-Phase Time Transfer
The wide application of GPS carrier-phase (CP) time transfer is limited by the problem of boundary discontinuity (BD). The discontinuity has two categories. One is “day boundary discontinuity,” which has been studied extensively and can be solved by a few methods [1–5]. The other category of discontinuity, called “anomaly boundary discontinuity (anomaly-BD),” comes from a GPS-measurements data ...
متن کاملGPS Jamming and GPS Carrier-Phase Time Transfer
This paper studies the impact of GPS jamming on GPS carrier-phase time transfer. To study this issue, at NIST, we have installed a commercial GPS jamming detector since 2014 April. During 2014 April – 2015 April, the detector detected more than 100 jamming events, though there had been a few outages of jamming detection. The jamming events usually last for less than 2 min. We find that almost a...
متن کاملGPS Carrier-Phase Time Transfer Boundary Discontinuity Investigation
We report on a study of the carrier-phase time transfer boundary discontinuity by the use of the precise point positioning (PPP) technique. Carrier-phase time transfer is first compared with two-way satellite time and frequency transfer (TWSTFT) between the same stations. It matches TWSTFT quite well and provides better short-term stability. Later, we extract 1-day data-arc boundary discontinui...
متن کاملA Gps Receiver Designed for Carrier-phase Time Transfer
The development of time transfer techniques using GPS carrier-phase observations promises the capability to deliver sub-nanosecond time transfer capabilities. Testing to date has shown that conventional GPS receivers introduce significant time offset in the carrier phase. NAVSYS have developed a GPS receiver capable of making observations with high phase stability. Test data is presented in thi...
