TRE-3S OEM GNSS Receiver Board

JAVAD TRE-3S OEM GNSS Receiver Board

The TRE-3S OEM GNSS receiver board from Javad GNSS, equipped with 874 GNSS channels, offers up to 200 Hz RTK, QZSS L6 signal decoding, precise navigation with stable digital filters, enhanced GLONASS inter-channel bias performance, and multipath rejection.



The TRE-3S OEM GNSS board from Javad GNSS, with 874 GNSS channels, allow tracking all current and future satellite signals. It also offers up to 200 Hz RTK and can track and decode the QZSS L6 (both L61 and L62) signal messages.

The TRE-3S offers highly stable digital filters (band characteristics do not change with age, input voltages, or temperature), improved GLONASS inter-channel bias performance (due to the flat digital filter shape), and excellent multipath rejection.

Embedded calibrator measures phase and code delays of each signal of each band. External calibration is not required.

The in-built netBrowser allows communicating with the receiver via HTTP using a browser without the Internet. TRE-3S is form, pin-out, and command compatible with the following OEM boards: TRE-G3T, TRE-3N, TRE-3, and TRE-3L.


  • In-band interference rejection (IBIR)
  • Spoofing detection
  • Advanced multipath reduction
  • Fast acquisition channels
  • 874 channel, all-in-view tracking
  • High accuracy velocity measurement
  • CAN interface
  • IRIG timecode output
  • Up to 64 GB of onboard storage
