4.3 - Anti-jam protection
The GPS6000-PRO combines two discrete layers of anti-jam
protection. When used together, these systems provide a high level
of resistance against the affects of both GNSS spoofing and GNSS
jamming.
The GNSS antenna incorporates class leading anti-jam technology,
providing reliable operation, even in hostile RF environments.
The GNSS decoder provides a second layer of protection, with
advanced anti-spoofing functionality.
Please contact us if you require further details regarding the operation
of these functions.

status of your GPS6000-PRO. In normal operation, the status
LED will be flashing green. A red LED indicates the system is not
