Timing GPS Receiver Module Model GT-84ADiscontinued Products

For Timing

GT-84A is the FURUNO's high sensitivity Time-Transfer GPS Receiver Modules that delivers highly accurate GPS timing.

Integrity is further improved because of its SBAS (WAAS) capability in addition to traditional T-RAIM (Time-Receiver Autonomous Integrity Monitor) function. Several new command sets have been added for easier use.

PPS output mode is available. For example, in "always output mode", 1PPS is output without satellite signals using the receiver's internal timing (no UTC synchronization). In "fixed observation point mode", one satellite signal is enough to output UTC synchronized 1PPS. application is infinite.


  • High accurate UTC time can be easily obtained worldwide.

  • High sensitivity ensures excellent reception in the most demanding applications

  • Small SMT package reducing the mounting area and mounting cost.

  • One satellite signal is enough to output UTC syncronized 1PPS.

  • Antenna current detection circuit allows you to ease maintenance work.
