Another GPS III milestone

Raytheon's GPS Launch and Checkout capability has received Interim Authorisation to Test (IATT).

The company received IATT security certification for the GPS Next Generation Operational Control System (GPS OCX) Launch and Checkout System (LCS) 4 months ahead of schedule.

The company received a one-year certification with no changes required, enabling it to move to the next stage of testing the LCS in preparation for the launch of the first GPS III satellite.

The Interim authorisation also covers Lockheed Martin's GPS III satellite support systems, including excercise and upload generation tools.

OCX is being developed in two 'blocks' using a commercial iterative software development process. There are 7 iterations in Block 1 and one in Block 2. LCS is the fifth Iteration of Block 1 - it successfully completed Critical Design Review in June.

The first GPS III satellite is in production at Lockheed Martin and is expected to be delivered to USAF 'flight-ready' in mid-2014.

GPS III satellites are expected to deliver 3-fold better accuracy, 8-times more powerful anti-jamming capabilities and a 25% life increase - they will also carry new civil signals interoperable with other GNSSs.
