The Canadian Army has completed testing NovAtel's GPS Anti-Jam Technology (GAJT) in live-firing conditions on the M777C1 Howitzer.
The trial was conducted at Canadian Forces Base Shilo in Manitoba under the Build in Canada Innovation Program (BCIP) of Public Services and Procurement Canada (formerly referred to as Public Works and Government Services Canada), the company said in a statement Thursday.
The BCIP helps companies to bridge the pre-commercialization gap by procuring and testing late stage innovative goods and services within the federal government before taking them to market.
GAJT was trialed on the M777C1 Howitzer. GAJT protects GPS-based navigation and precise timing receivers from intentional jamming and accidental interference. It is a null-forming antenna system which ensures satellite signals necessary to compute position and time are always available. It is a Commercial Off-the-Shelf (COTS) product, and comes in versions suitable for land, sea, fixed installations and smaller platforms such as UAVs. Military vehicles and platforms, networks and timing infrastructure also benefit from the protection that GAJT provides.
There is no need to replace GPS receivers already installed, as GAJT works with civil and military receivers, and is ready for M-Code.
The M777C1 lightweight 155-mm towed Howitzer provides close fire support without sacrificing range, stability, accuracy or durability. It is equipped with a Digital Gun Management System which enables the crew to engage targets, particularly when employing precision-guided munitions that use location data from GPS satellites.
