STW-CV Series Satellite Co-visibility Time- Frequency Transfer/Measurement Equipment

　　The STW-CV Series Satellite Co-visibility Time-Frequency Transfer and Measurement Equipment receives GPS and Beidou satellite signals and is equipped with a high-performance internal clock source (rubidium clock or crystal oscillator). It utilizes satellite co-visibility technology to achieve long-distance high-precision time synchronization or measurement. The main station of the equipment can receive external 10MHz, 1PPS signals, while the remote station can output frequency time code pulse signals and save standard co-visibility files in RINEX and GGTTS formats.

Product features

Supports standard/real-time co-visibility technology

Can perform co-visibility through Beidou (B1/B3) and GPS satellites

Can receive external 10MHz, 1PPS+TOD signals for remote measurement or time transfer

Can choose between a rubidium clock or crystal oscillator as the clock source and output time-frequency signals

Can establish co-visibility links using communication methods such as RD short messages, 4/5G wireless communication, and Ethernet

Can generate RINEX, GGTTS protocol comparison standard data files, accessible via FTP

Co-visibility comparison accuracy: Zero baseline <1ns; Long baseline <3ns
