Javad GNSS offers spoofing alert for surveyors

December 1, 2017  - By

Spoofing — the generation of false and misleading GPS signals by “bad actors” — is becoming an increasing problem for all GPS users, and surveyors just as much as everyone else should be knowledgable and take countermeasures.

Javad GNSS has announced that spoofer detection is now available on all of its OEM boards. If the receivers equipped with such boards detect more than one correlation peak for any PRN code, they warn the user of the presence of spoofing (false signals) and identify the spoofed satellites.

The receivers then switch to other signals and sensors that are not being spoofed, to maintain accurate positioning. The user can also employ the receiver to try to identify the direction from which the spoofing signals are originating.
