GPS Block IIR-M and IIF satellites began transmitting CNAV messages on the L2C and L5 signals, on Monday (April 28, 2014).
In a Notice Advisory to NAVSTAR Users (NANU), Air Force Space Command announced that it would begin implementing the civil navigation Message Types (MTs) 10 and 11 (with satellite ephemerides), 30 (satellite clock data, and corrections for ionospheric and group delay), and 33 (parameters related to correlating coordinated universal time (UTC-USNO) time with GPS system time). MT12 (reduced almanac) will not be broadcast at this time.

Brad ParkinsonAmong the key topics to come out of this year’s European Navigation Conference (ENC 2014) in Rotterdam is how safe — or unsafe — we really are, and who in Europe cares. The answer is, a lot of people care, but almost no one can do anything about it.
Professor David Last, strategic advisor at the General Lighthouse Authorities of the UK & Ireland, made the case before the conference had even started, at the pre-conference “Resilient PNT Forum.”

The Republic of Korea will return next month with a new tender for implementing an eLoran system, driven by North Korean jamming of GPS in the region.
Initial plans to establish an eLoran-based back up faltered due to technical and requirements challenges that held prospective vendors back from bidding on the contracts. Details of the new plan were revealed in a presentation today (April 14, 2014) at a Resilient PNT Forum held in Rotterdam, The Netherlands, in advance of the European Navigation Conference (ENC 2014).

The Russians may have taken a rain check, but Asian representatives were out in force at this year’s Munich Satellite Navigation Summit, held last week (March 25–27, 2014). The general message from China, Japan, and India was that they are moving forward quickly with their own GNSS systems, while seeking active cooperation, both technical and commercial, with international partners.

The U.S. Air Force has awarded Lockheed Martin more than $245 million in contract options to complete production of its seventh and eighth GPS Block III satellites.
The two space vehicles (SVs 07–08) received initial funding under a February 2013 long-lead material contract for the Air Force’s second set of four satellites, GPS III SV 05–08. Similar to this current award announced yesterday (April 1, 2014), the Air Force exercised an option to complete production of SVs 05–06 in December 2013.

The Federal Aviation Administration (FAA) has announced plans to establish within the next year a Center of Excellence (COE) for its Unmanned Aircraft Systems (UAS) Research, Engineering, and Development Program.
An FAA notice published last Friday (March 28, 2014) said that the agency will launch a competitive search for a team to lead the initiative as part of the FAA’s effort to integrate UAS into the National Airspace System (NAS). A draft solicitation will be available on or before April 18.
