High-precision time synchronization

Высокоточная временная синхронизация

GPS UTC Time Synchronization Unit (UTC TIME) — TRIGGER TIMING UNIT (Revision 2.1)

Specially designed industrial high precision GPS Precision Time (UTC Time) system synchronization module with an accuracy of 1 microsecond

The unit is used as a source for determining the exact time of start marks (synchronization system) and control signals of navigation, control and recording equipment during geophysical engineering surveys and other marine or onshore works.


The unit provides accurate GPS (UTC) time detection/synchronization, multiple serial interfaces and TTL outputs are also time referenced.

The module allows you to record the exact GPS (UTC) time of a TTL pulse trigger and perform remote time synchronization of multiple devices or systems.

Time-based I/O delays and different string formats can be programmed optionally.

Functional capabilities

  • Up to 2 digital remote trigger outputs (TTL Active HI/LO) with adjustable delays and durations (system scalability up to 8 outputs/4 units)
  • Digital input/output for precise time stamping (TTL Active HI/LO) with adjustable delays and durations (system scalability up to 4 inputs/4 units)
  • 4 RS232 serial ports: navigation string formats, GCS90, and other various formats with programmability
  • Master-Slave mode functionality for synchronization of multiple units and remote systems

  • 1 x 1PPS (Pulse Per Second) Input / Output Connector
  • 1 x GPS Serial Input / Output Time Message (NMEA ZDA or TSIP)
  • 1 x Acutime 360 Connector — Multi-GNSS (GPS, GLONASS, Beidou, Galileo)
  • 1 x a built-in Master GPS (Time) clock is used to keep system time to better than 1 microseconds
  • Green LEDs indicating on the front panel
  • Specialized Software for GPS Time Control & Settings

  • GPS, GLONASS, Beidou, Galileo
