Evaluation of TTS-3, a new multi-system time receiver

Summary form only given: There are now four types of navigation satellite available for time and frequency transfer: GPS, GLONASS, WAAS and EGNOS. This paper describes briefly a new time-transfer receiver TTS-3, based on a Javad Legacy plate, which allows observations of these satellites simultaneously in multi-channel, multi-frequency mode. The following codes are used: C/A-code for GPS, WAAS, EGNOS and GLONASS, P-code for GLONASS, and reconstructed P-code for GPS. The receiver hardware, the treatment of the observations, and the output data fulfil the recommendations of the CCTF Group on GNSS Time Transfer Standards (CGGTTS). The paper reports an on-site evaluation of the TTS-3 stability, and first tests of multi-system time-transfers.
