TTS-3 GPS/GLONASS/WAAS/EGNOS Time Transfer System
The Astrogeodynamical Observatory (AOS) of the Space Research Centre following a very successful TTS-2,
has developed a new high-performance Time Transfer System TTS-3. The TTS-3 as TTS-2, is manufactured
by PikTime Systems in cooperation with the AOS.
At present the TTS-3 receiver carries observations on L1 and L2 frequencies for both GPS and GLONASS, receiving GPS C/A and P1 and P-2 codes, GLONASS C/A and P1 and P2 codes, and EGNOS. For time transfer ionospherefree linear combination of P1 and P2 called P3 is used. The TTS-3 consists of a PC industrial computer, a PC card time interval counter, a GNSS 40 channel, appropriate software, an antenna, and connecting cables. The TTS-3 precision in multi-channel P3 mode when using measurements precise ephemerides may reach 1 ns. Both carrier frequency and code measurements are available in RINEX format There are several options available for TTS-3 depending on requested performance. The TTS-3 can be equipped with a temperature-stabilized antenna. The system allows an easy upgrade of
presently available and future options.
