Javad TRIUMPH chip counteracts spoofing
Javad is busting spoofers. With 864 channels and about 130,000 quick acquisition correlators in its TRIUMPH chip, Javad has resources to assign more than one channel to each satellite to find all signals that are transmitted with that GNSS satellite PRN code.
If more than one reasonable and consistent correlation peak is detected for any PRN code, the GNSS knows that it is being spoofed and can identify the spoofed signals and use the position solution provided by all other clean signals (L1, L2, L5, GPS, GLONASS, Galileo, Beidou, etc.) to identify the spoofer signal and use the real satellite measurement. If all GNSS signals are spoofed or jammed, an alarm warns the user to ignore GNSS and use other sensors in their integrated system.
