What is a "Gps Jamming Test"? The Most Authoritative Explanation.
What is GPS jamming?
GPS jamming is a technique that consists of canceling the radio signals or waves emitted by a GPS device. This interference occurs on purpose and is done through radio frequency signals. Its objective is to interfere with a signal on the same frequency and with a power greater than that of GPS devices.Can GPS be jammed or spoofed?
GPS technology has been vulnerable to jamming and spoofing for years due to the weak signal from GPS satellites. GPS signals can be jammed or spoofed relatively easily and for low cost, and methods are evolving. For example, truckers across the U.S. can purchase $10 GPS jammers to prevent their employers from tracking their movements.How does a jamming detection system work?
A jamming detection system basically works like a receiver. Which when detecting a signal of the same frequency and with a higher power, activates an alert and jamming detection event. How to protect yourself from GPS jamming?How do GNSS satellites detect GPS jammers?
Three GNSS radio occultation (RO) satellites were tasked to collect raw Intermediate Frequency (IF) data during active jamming tests at a location within the continental U.S. The antenna polarization and orientation of Spire’s 3U RO CubeSats proved to be suitable for detecting signals from certain GPS jammers.
