What is a "Anti Jamming Gps Antenna"? The Most Authoritative Explanation.
What is a GPS anti-jam?
A simple low power jammer, readily available via the World Wide Web, can overpower GPS signals within a large area, denying a position solution and timing. GPS anti-jam technology is quickly evolving.
How do GNSS anti-jamming receivers work?
GNSS anti-jamming receivers may also be able to detect jamming signals by measuring signal strength – these signals may be higher-powered than the weak legitimate GNSS signals. Anti-jam antennas can also be installed that can figure out the direction of the jamming signal and introduce “nulls” that decrease the effectiveness of the jammers.
What is anti-jamming technology?
Anti-jamming technology includes the use of special GNSS receivers that use filtering and signal processing to reject unwanted signals, which is especially effective for out-of-band interference.
How much power does a GPS jammer use?
Even a small jammer of about 10 Watts power can disrupt an unprotected C/A Code receiver for about 30 kilometres (line of sight). GPS Anti-Jamming uses power minimization to reduce the effect of interference and jamming so that the GPS receiver can continue to operate correctly.
