TR-3N OEM GNSS Receiver Board

JAVAD TR-3N OEM GNSS Receiver Board

The TR-3N OEM GNSS receiver board from JAVAD GNSS boasts an impressive 864 channels for comprehensive satellite signal tracking, along with a versatile power supply and ample onboard storage.



The TR-3N OEM GNSS receiver board from JAVAD GNSS has 864 GNSS channels which allow tracking all current and future satellite signals. The onboard power supply accepts any voltage from +4.5 to +40 volts and delivers cleanly filtered voltage where needed. This eliminates the risk of power contamination (ripples) that can be created when clean power is generated elsewhere and delivered to the board via cables.

The TR-3N GNSS receiver board includes drivers for four LEDs, ON/OFF and function button controllers. It comes with a significant amount of flash for data storage. The CAN interface is provided complete with all associated hardware and firmware, not just the CAN bus. The same is true with all the serial RS232/RS422 ports. In addition to timing strobe and event marker, the TR-3N OEM GNSS board includes the option of complete IRIG timing system.


  • Advanced multipath reduction
  • Fast acquisition channels
  • 864 channel, all-in-view tracking
  • High accuracy velocity measurement
  • CAN interface
  • IRIG timecode output
  • Up to 16 GB of onboard storage
