Antispoofing is a technique for identifying and dropping packets that have a false source address.
In a spoofing attack, the source address of an incoming packet is changed to make it appear as if it is coming from a known, trusted source. Spoofed packets are commonly used to carry out denial of service (DoS) attacks, exploit network and system vulnerabilities and gain unauthorized access to corporate networks and data.
GAJT® - GPS Anti-Jam Technology NovAtel's approach to the problem is to build a range of compact and affordable anti-jam systems for land, sea, air (including unmanned aerial systems), and fixed installations.
GAJT is a null-forming system that preserves the antenna's view of the GPS satellites while ignoring jammers, ensuring the satellite signals required to compute precise position remain available.
The GAJT range of products provides anti-jam performance at a significantly lower cost than others and is available off-the-shelf for rapid deployment.
