Signed budget includes full GPS funding, except for $2M IIF reduction

December 16, 2015By

On Nov. 25, 2015, President Obama signed the National Defense Authorization Act (NDAA) for Fiscal Year 2016, after vetoing a previous version. The enacted NDAA complies with the two-year budget agreement, which called for a reduction in defense spending.

To L2C or Not to L2C? That Is the Operational Question.

July 22, 2015By

Half of the GPS constellation now transmits the new civil signal, L2C. In a matter of weeks, that number will crest into the majority of the constellation when IIF-10 is set active and operational to users. By the end of the year or early 2016, look for 18 usable satellites transmitting L2C. That could be considered a nominal initial operating... read more
