Canadian Army tests anti-jam system

The Canadian Army has successfully tested NovAtel’s GPS Anti-Jam Technology (GAJT) in live-firing conditions on the M777C1 Howitzer.

The trial was carried out to test GAJT’s robustness under demanding conditions. GAJT is designed to protect GPS-based navigation and precise timing receivers from intentional jamming and accidental interference. The null-forming antenna system ensures satellite signals necessary to compute position and time are always available. 

GAJT has been designed as a COTS solution in a number of versions for land, sea, fixed installations and smaller platforms such as UAVs. M-Code ready and able to operate with civil and military receivers, GAJT can protect military vehicles and platforms, networks and timing infrastructure. There is no need to replace GPS receivers already installed.

Capt Thomas Booth, CD RCCS, the GAJT trial director, said: ‘Through our independent testing, we saw that NovAtel’s GAJT-AE-N continued to work under the most demanding circumstances, indicating it could potentially be employed to preserve a combat force’s freedom of action in a hostile and unforgiving environment.’

The trial, conducted out at Canadian Forces Base Shilo in Manitoba, was carried out as part of the Canadian government’s Build in Canada Innovation Program. This programme is being run to support innovation by procuring and testing late stage products and services within the federal government before companies take them to market.
