Making GPS and Galileo Play Nice:

Lockheed Martin and EADS Astrium recently concluded they could work together to ensure interoperability between the US Global Positioning System III satellites and the European Galileo navigation satellite program. The two companies will perform systems engineering and technical assistance tasks for each other covering interoperability, integrity, and optimization of joint constellation performance. They also plan to offer reciprocal bids on hardware and software within policy and export constraints.
