NovAtel’s GPS Anti-Jam Technology (GAJT) has been selected for the United Kingdom’s Type 26 frigates to meet a requirement as part of a protected navigation system. The frigates are 21st-century warships that will replace the Type 23 frigate as the workhorse of the British Fleet, undertaking the Royal Navy’s three core roles — warfighting, maritime security and international engagement — on the world stage. GAJT-710MS GAJT protects GPS-based navigation and precise timing receivers from intentional jamming and accidental interference, ensuring that the 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 unmanned aerial vehicles (UAVs). Warships, military vehicles and platforms, networks and timing infrastructure can all benefit from the protection that GAJT provides. There is no need to replace GPS receivers already installed, because GAJT works with civil and military receivers including SAASM and M-code. The Type 26 frigates of the British Fleet will use NovAtel anti-jam technology. (Photo: BAE Systems) “The selection of GAJT for the Type 26 frigates is the result of cooperation between Drumgrange, with its proven track record for rapid realisation of demanding defence design tasks, and Forsberg Services, an established navigation systems company and NovAtel dealer whose high quality manufacturing was instrumental to the project,” said Peter Soar, business development manager for military and defence at NovAtel. “GAJT is in use operationally and has been shipped to 16 allied nations around the globe. We are grateful for the rigorous technology selection process conducted which led to this choice.” NovAtel’s commitment to precise, assured positioning and timing is central to the design of the GAJT antenna. The company’s lean manufacturing techniques and quality processes mean that it can ramp up quickly to meet volume requirements. Reliability is assured by NovAtel’s industry-best low return rate.
