Activities are now underway by a team led by Lockheed Martin [NYSE: LTM] to reconfigure a modernized Global Positioning System Block IIR (GPS IIR-M) satellite. Included in this project will be a new demo payload to temporarily transmit a third civil signal following a successful review by the U.S. Air Force. Lockheed Martin and navigation payload supplier, ITT (Clifton, N.J.) are on-schedule under a $6 million contract award last April. The contract specified the development and integration of a payload that will provide an on-orbit demo for the new civil signal.
Located on the L5 frequency, which is 1176.45Mhz, the signal will comply with international radio frequency spectrum requirements. An operational third civil signal to improve accuracy and performance capabilities of the system will be included in future generations of GPS spacecraft. The GPS constellation provides critical situational awareness and precision weapon guidance for the military plus supports a range of civil, scientific and commercial functions from air traffic control to the Internet with precision location and timing info—King Of Prussia, Pennsylvania
