The company said in a statement Monday that each of its new Global Positioning System IIR-M satellites now carries an upgraded antenna panel that gives them boosted signal power when they transmit to stations on the ground.
The new satellites -- three of which have been successfully launched and deployed in the past six months -- are also equipped to transmit two new military signals to increase their accuracy. They also carry new improved encryption/coding and anti-jamming equipment, Lockheed Martin said.
The GPS satellites are equipped with a second civil signal that will give users an open access signal on a different frequency, the company said.
