Exelis completes GPS updates

31 January 2014

Exelis (NYSE: XLS) said it has completed several software upgrades for the new Global Positioning System Next Generation Operational Control System, or GPS OCX.

Integration and testing were recently conducted on iteration 1.5 of the OCX navigation, encryption and mission upload generator (MUG), software.

The new version of GPS software will help ground controllers better understand the satellites´ exact positioning in space. The encryption software is also designed to automatically code and decode GPS signals, facilitating the exchange of user information by securely transmitting navigation payload data between the OCX ground system and the orbiting constellation of satellites.

The MUG software is responsible for creating spacecraft payload updates to refresh the navigation data transmitted to all GPS users. This data is typically generated for each satellite multiple times a day and helps to consistently minimize user error.

Once the new operational control segment is implemented, GPS will improve a variety of business and economic practices, including air traffic control, crop management, and environmental monitoring, among others. The new capabilities offered by GPS modernization will also provide military users increased accuracy, availability, anti-jam power and international interoperability.
