Lockheed said the three-day test evaluated the satellite’s command and control functions.
The companies also tested software and hardware of the GPS III satellite needed for on-console procedures for launch and early orbit mission.
Keoki Jackson, vice president of Lockheed’s navigation systems mission area, said in a release the satellites will be used in the military, civilian and commercial sectors.
According to Lockheed, the GPS III mission readiness timeline includes five short-duration exercises and six five-day mission rehearsals leading up to launch.
Lockheed holds a $238 million contract to produce satellite numbers three and four and Raytheon developed the GPS operational control system.
