Global Navigation Satellite Systems Engineering, Policy, and Design
The importance of geospatial data being harmonized across Europe via a common coordinate system was stressed at the recent EUREF 2017 Symposium in Wroclaw, Poland, where the European GNSS Agency (GSA) discussed Galileo’s role in helping the mapping and surveying sector.

Lockheed Martin’s second GPS III satellite is now assembled and preparing for environmental testing, and the third satellite is close behind, having just received its navigation payload.
In a specialized cleanroom designed to streamline satellite production, the company is in full production building GPS III – the world’s most powerful GPS satellites, near Denver, Colorado.

Photo courtesy of Air Force.The White House is asking Congress to boost overall funding for the GPS program back over $1 billion, with the largest infusion of new money earmarked to cover the cost growth of the Next Generation Operational Control System (OCX).
If approved, overall spending on the GPS program would reach $1.09 billion in fiscal year 2018 (FY18) with funding for OCX surging to $510.94 million from the $393.27 million allocated by Congress for FY17.

With designs on providing a boost to navigation safety and efficiency for commercial and general aviation, Raytheon Company on May 18 launched its GEO 6 satellite payload into orbit for its 12-year mission. It is the latest payload to support the Federal Aviation Administration’s Wide Area Augmentation System (WAAS) which enhances the reliability and accuracy of GPS signals for directing air travel.

The new GPS ground system has passed its most recent in-depth review and completed a schedule and budget re-baselining though a new government watchdog report says the program remains at "high risk of cost overruns, schedule delays and performance shortfalls."

After a couple of changes in direction and spending some $18 million to verify the technical chops of their most likely suppliers, defense officials appear ready to buy up to 22 new GPS III spacecraft. Although three firms are now well positioned to bid on the potentially lucrative contract, the Defense Department continues to leave the contracting door ajar for newcomers, just in case.

Space debris is becoming a bigger problem for space agencies and private companies, and NASA and the Department of Defense (DoD) are just two of many organizations around the globe that are concerned. Earlier this month experts gathered in Germany to discuss the problem and to review possible solutions.

In addition, the company completed a baseline procedure to recertify the troubled OCX program, which was approved by the U.S. Air Force, at the end of March, said Bill Sullivan, Raytheon vice president and program manager for GPS OCX, at the recent 33rd annual Space Symposium meeting in Colorado Springs, Colorado.

Q: Would you prefer to have more signals or more satellites?
A: This is somewhat of a classic GNSS question, but before getting to the answer, let’s seek some clarity about what is being asked. First, by definition, “more” signals or “more” systems must be referenced against some baseline configuration. This is commonly assumed to be a GPS L1 C/A solution, and this assumption is also used herein.

With two federal budgets in play simultaneously, defense spending increases being proposed from multiple directions and a looming government shutdown it’s easy to lose track of where things stand with GPS funding.
