The UK division of Raytheon is thrilled to be the company of choice for producing Britain’s first GPS enabled anti-jam antenna system to be specifically used for military purposes on land vehicles. The company has a history with both the United States and the United Kingdom for producing naval and military aircraft anti-jam systems.
Most signals sent from one of the earth orbiting satellites in the Global Positioning System to earth are usually at their weakest strength by the time they hit the receiver on earth. Although the receiver can usually decipher and somewhat steady the necessary signal, that signal is still open to attack by much stronger opposing jamming or interference signals. Even a jamming power unit as low as 1 watt is enough to interfere with GPS signals within a sizeable radius, leaving the vulnerable receivers in worthless disorder.
To protect the position of and GPS communication with the receiver, GPS anti-jamming technology is used to cancel out the interference caused by enemy signal-scrambling equipment and provide a clear GPS tracking signal of the appropriate individuals. Such anti-jamming equipment, in the form of an antenna, is usually mounted on military vehicles for purposes in combat zones and training exercises. This monitoring technology protects the armed forces’ soldiers by keeping their current location known with constant and up-to-date GPS tracked coordinates and allows them to stay in unhindered communication with superior officers (and possible change of orders).
A typical GPS anti-jamming antenna is often larger than a typical GPS antenna because of the sheer number of elements its construction requires. This size concern in some cases limits the GPS anti-jam antenna’s suitability in multiple functions or platforms.
And the winner is …
Raytheon, apparently; the company has built a strong reputation for punctual construction and distribution of their various GPS enabled anti-jam collections, having presented more than 7,000 items to the United States and Britain. The UK Ministry of Defense has been assured that the systems will be completed within six months’ time. The contract follows upon the heels of an Urgent Operational Requirement from the Ministry of Defense, placing a rush-order on the anti-jamming equipment.
