Though the schedule is still uncertain, progress is being made on completing the new GPS ground system, said Air Force Secretary Deborah Lee James, who credited a crack group of private-sector computer wizards with helping get the program back on course.

Calling the GPS Next Generation Operational Control System (OCX), a "terribly, terribly important program," James said, however, she still did not consider the software-focused effort to be "out of the woods."

Vidal Ashkenazi Awarded OBE for GNSS Role in Services to Science

Professor Vidal Ashkenazi OBE

Nottingham Scientific Ltd (NSL) has announced that the company’s founder and CEO, Professor Vidal Ashkenazi, has been named an officer of the Order of the British Empire (OBE ) in the 2017 New Year’s Honors List for “Services to Science.”

The OBE was created by King George V in 1917 and is awarded by the ruling monarch of the United Kingdom, currently Queen Elizabeth II. The honor recognizes distinguished service to the arts and sciences, public services outside the civil service, and work with charitable and welfare organizations.

The U.S. Air Force Space and Missile Systems Center (SMC) says it continues to work on GPS III ceramic capacitor testing and plans to have an updated launch schedule published late next month.

As Inside GNSS reported, the first GPS III satellite’s delivery, originally scheduled for August, was delayed by four months because of a Lockheed Martin subcontractor’s failure to test a ceramic capacitor.

Defense Authorization Bill Signals Full GPS Funding, Pushes GPS Back-Up

Yesterday (December 23, 2016) President Obama signed the National Defense Authorization Act (NDAA) for Fiscal Year 2017, a $619-billion bill with a number of provisions affecting satellite navigation.

The legislation (S. 2943) fully authorizes the administration’s requests for all the elements of the GPS program — and signals indirectly that appropriators eventually will provide comparable support — although the NDAA does put additional requirements on those developing the new GPS ground system.

European Commission Declares Galileo Initial Services Available for Use

Today (December 15, 2016) the European Commission (EC), owner of Europe’s GNSS system, Galileo, formally announced the start of Galileo Initial Services, the first step towards full operational capability.

Further launches will continue to build the satellite constellation, which will gradually improve the system performance and availability worldwide.

NASA Launches CYGNSS Space-Based Hurricane Watch

NASA successfully launched eight Cyclone Global Navigation Satellite System (CYGNSS) microsatellites this morning (December 15, 2016) from Cape Canaveral Air Force Station in Florida.

The CYGNSS spacecraft rode into orbit onboard an Orbital ATK air-launched Pegasus XL rocket. Orbital ATK’s modified L-1011 aircraft deployed the Pegasus XL and its CYNGSS payload at 39,000 feet, the agency said.

The U.S. Air Force has approved Lockheed Martin’s current GPS satellite ground control system upgrade to enable it to operate with more powerful and accurate GPS III satellites, the company said.

The Air Force’s Critical Design Review (CDR) for the Contingency Operations (COps) contract, completed on November 17, allows Lockheed Martin to proceed with the modification of the existing Architecture Evolution Plan (AEP) Operational Control Segment. The AEP, maintained by Lockheed Martin, controls the 31 GPS IIR, IIR-M and IIF satellites in orbit.

Ligado Networks and Topcon Reach Spectrum Use Agreement

Ligado Networks has announced a cooperation agreement with Topcon Positioning Systems that removes another barrier to the wireless broadband company’s proposed 5G network rollout.

According to a November 29 letter to the Federal Communications Commission (FCC), the agreement calls for future coordination prior to network development and for any mitigation efforts. Topcon also urged the FCC to grant Ligado’s modification applications to enable ground-based services on its mid-band spectrum.

Lockheed Martin Advances GPS Ground Control System for U.S. Air Force

The Air Force’s Global Positioning Systems Directorate contracted the CUP2 upgrade.

Lockheed Martin has announced a major upgrade to modernize the GPS ground control system, the company said. The commercial-off-the-shelf (COTS) upgrade no. 2 (CUP2) project, which became operational in mid-October to manage the 31 GPS satellites, is the latest step in the U.S. Air Force’s plan to refresh technology and transform the legacy operational control segment, also known as the Architecture Evolution Plan (AEP), the company said.

GAO: New GPS Ground System, Not GPS III Engineering, Primary Cause for Delays

Government watchdogs said in a new report that schedule slippages in the new GPS ground system — which in October had another four months added to its repeatedly extended schedule — are more of a factor in delays to GPS modernization than technical problems with the satellite’s payload.

GPS, GLONASS, Galileo, and BeiDou for Mobile Devices

The navigation sensors for location-based services (LBS) are complex technical systems. Modern technical science can answer most questions about the optimality of particular position determination methods, signal processing algorithms, electronic circuits or similar well-defined problems, but the rigorous answer to the questions concerning the optimal LBS positioning sensor are still a big problem.
