Extending The Tracking Schedule Of A Single-Channel GPS Time Receiver

Abstract

There are now available four types of navigation satellites suitable for time and frequency transfer: GPS, GLONASS, WAAS, and EGNOS. This paper describes a new time transfer system TTS-3, based on a Javad Legacy receiver, allowing observations of these satellites simultaneously in multi-channel and multi-frequency mode. The following codes are used: C/A code for GPS, WAAS, EGNOS, and GLONASS; P-code for GLONASS; and reconstructed Pcode for GPS. Receiver hardware, treatment of observations, and output data fulfill the recommendations of the CCTF Group on GNSS Time Transfer Standards (CGGTTS). The structure of the new time transfer unit is described in brief, and the results of some multi-system time transfer tests are presented.
