New LightSquared, the firm reconstituted from the original LightSquared wireless broadband company upon its exit from bankruptcy, has proposed a settlement of lawsuits filed against Garmin and Trimble Navigation, which would end most of the company’s legal action against the GPS community.

Europe’s GNSS program placed two more satellites into orbit today (December 17, 2015), doubling the number of Galileo spacecraft in space in the course of nine months from 6 to 12.
Galileo 11 and 12 — the full Operational Capability (FOC) satellites numbers 7 and 8 — lifted off together at 6:51 a.m. EST (12:51 CET, 11:51 UTC, 8:51 a.m. local time) atop a Soyuz rocket from Europe’s spaceport near Kourou, French Guiana.

The National Executive Committee for Space-Based Positioning, Navigation, and Timing (PNT ExCom) has recommended using enhanced Loran (eLoran) as a near-term alternative to GPS for essential timing data while it determines what capabilities are needed for a comprehensive GPS backup, officials told Congress this week.

The Air Force Second Space Operations Squadron (2 SOPS) reports that the GPS Block IIF-11, (SVN-73/PRN-10) satellite has been set healthy and is fully operational. Launched October 31, SVN-73 has replaced SVN-47 in the E plane slot E2.
In a change of direction the new LightSquared team has dropped its lawsuit against the federal government and reached a separate settlement in its lawsuit against Deere & Company that has wide-ranging implications for the GNSS community.
Under the deal LightSquared has agreed to lock in lower power limits and drop its push for GPS receiver standards in exchange for Deere dropping its opposition to LightSquared’s terrestrial broadband network.

The Air Force is weighing its options for a new GPS ground system after a detailed review last week revealed the system would be further delayed — perhaps to as late as 2023.

Torrance, CAThe Southern California Section of the Institute of Navigation’s December meeting will take place at the John Deere facility in Torrance, CA on December 15, 2015.
Dr. Chun Yang will speak at the meeting. The title of the talk is Sharpening Peak Performance of GPS Signals. In this talk, the variable IF tracking architecture that improves the
peak performance will be presented together with possible implementation
schemes. Simulation results will be used for illustration and analysis.
Concept design for the world’s largest airport passenger terminal – the Beijing New Airport Terminal Building. Zaha Hadid Architects drawingTrimble announced today (December 8, 2015) that it has received a contract extension to use the company’s technology from Trimble to integrate construction and operations for the high-profile Beijing New Airport Project, expected to be the world’s largest when completed at an estimated cost of $13.1 billion.
In April, Trimble won the initial bid to supply the project with a construction information management system. Based on the success of the solution to date, the contract has been extended to include additional machine control systems for soil stabilization.

Another pair of Galileo satellites is now fully operational, broadcasting navigation signals and, since Tuesday (December 1, 2015), transmitting search and rescue messages worldwide.
Galileos 7 and 8 were launched from Europe’s Spaceport in French Guiana on March 27. Their navigation payloads underwent a lengthy test campaign confirming their performance and integration into the worldwide Galileo ground network.

The House and Senate, now working with a fresh extension, have until December 4 to hammer out the details of a new highway bill. The legislation will authorize — but not necessarily appropriate — Highway Fund monies for state roadways for as long as six years and likely spin up research into intelligent transportation systems (ITS) and connected and autonomous vehicle technology — three sectors that rely on GNSS for success.

The Department of Homeland Security (DHS) is reorganizing the vast directorate responsible for cybersecurity and the nation’s critical infrastructure. Thus far, however, protecting the GPS signals essential to most of that infrastructure hasn’t rated a public mention in the plans.
The reorganization of the National Protection and Programs Directorate (NPPD) got underway in July, the month after the Office of Personnel Management revealed a computer beach that left the fingerprints and personal information of 5.6 million federal employees in the hands of hackers.
