GAJT-410ML anti-jam antenna

Jamming and interference, whether intentional or unintentional, can seriously degrade GPS position, navigation and time availability—even to the point of total solution denial. Jammers create excessive noise, overpowering the low power GPS signals and saturating the electronics in a GPS receiver front end.

The GAJT-410ML is the next evolution of NovAtel’s battle-proven anti-jam technology. It maintains the high levels of interference rejection performance as in the larger GAJT-710ML system, but in a lower size, weight and power (SWaP) design. Designed specifically for rapid integration into space-constrained military land applications, this easy-to-use system protects GPS-based navigation and precise timing receivers, including M-Code, from both intentional jamming and accidental interference.


Features and Benefits:

  • Simultaneous GPS L1 and L2 Operates with civil and military GPS receivers as well as M-Code
  • Lower size, weight and power (SWaP) enclosure includes a combined antenna array and null forming electronics making it suitable for installation on a wide range of land vehicles
  • Integrates easily into new or legacy fleets and uses the existing Radio Frequency (RF) cable to supply data and power directly to the unit to reduce the need for costly platform modifications
  • The Power Injector Data Converter (PIDC™) provides situational awareness by accessing the jammer status and direction-finding (DF) capabilities of the GAJT-410ML across the single RF cable
