Preliminary Results of the TTS4 Time Transfer Receiver Investigation

N. Koshelyaevsky and I. Mazur

Abstract:	Three new TTS4 GPS/GLONASS/GALILEO time transfer receivers (#119, #121 and #122) have been installed in VNIIFTRI facility and investigated at a short baseline. These instruments have been compared first with each other and authorized receiver type TTS3 #026, which in-turn have been differentially calibrated relative to the BIPM receiver. Then receiver TTS4 #121 was moved to Khabarovsk and installed in a new secondary time laboratory facility. During these experiments, receiver #122’s software was updated from version 2.8 to 2.11. This paper delivers detailed results, both short baseline and long (more than 6,000 km) baseline.
