Global Navigation Satellite Systems Engineering, Policy, and Design
The U.S. military is moving toward using the signals of other satellite navigation constellations to help ensure access to positioning and timing information and to potentially thwart spoofing.
The impending shift came to light in remarks made by Air Force Chief of Staff Gen. Mark Welsh III during a talk last week (April 23, 2014) at the National Press Club.

Perhaps taking a page of Russia’s playbook for mandating use of GLONASS in certain equipment, European officials are looking into the possibility of requiring the addition of Galileo capability to mobile phones and other device and platforms.
As it has become clear that the European GNSS will be the third or fourth GNSS available — after GPS, GLONASS, and probably BeiDou — the European Union’s executive body, the European Commission, is exploring non-market strategies to increase adoption of Galileo by manufacturers and users.

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.”

Russia’s GLONASS satellite navigation system reportedly suffered another major disruption on Tuesday (April 15, 2014), with eight satellites malfunctioning and another going off the air entirely.
According to the Russian Interfax news agency as reported by the Moscow Times, eight GLONASS satellites malfunctioned for a half-hour period beginning shortly after 1 a.m. Moscow Time.

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.
