First GPS III Satellite Completes Operational ThermoVac Testing in Simulated Harsh Space Environment

Lockheed Martin announced today (February 3, 2016) that the first GPS III satellite successfully completed system-level Thermal Vacuum (TVAC) testing on December 23, validating the design of the entire assembled satellite.
 
TVAC is a rigorous test designed to prove a satellite’s integrity and operational capabilities by subjecting it to prolonged cycles of simulated space temperature extremes in a special depressurized chamber.

Legislation to Stop U.S. Use of Russian Rocket Engines Could Affect GPS

Legislation to Stop U.S. Use of Russian Rocket Engines Could Affect GPS

U.S. Senator John McCain

If approved, legislation halting the use of a Russian rocket engine could force delays in the launch of U.S. military satellites, including, potentially, GPS III spacecraft planned for launch beginning next year.

The bill, introduced this week by Sen. John McCain R-Arizona, the chairman of the Senate Armed Services Committee, and House Majority Leader Kevin McCarthy, R-California, would ban the use of Russian RD-180 rocket engines for the evolved expendable launch vehicle program (EELV).
