Comparing Code Data From Carrier-Phase GPS Receivers to Other Time Transfer Methods at the U.S. Naval Observatory

Abstract

There has been considerable interest in recent years concerning the use of pseudorange data from RINEX files to perform time transfer. The U.S. Naval Observatory (USNO) has been actively involved in developing this technology as an alternative time transfer method between its Washington, DC and Colorado Springs, CO sites. This paper compares the time solutions derived from the IGS RINEX files to Two-Way Satellite Time Transfer (TWSTT). It will also show the IGS data, when converted to Common GPS GLONASS Time Transfer Standard (CGGTTS) format, can be useful in detecting problems and act as an additional verification tool when time transfer operations appear to be normal.
