Global Navigation Satellite Systems Engineering, Policy, and Design
The Air Force Life Cycle Management Center (AFLCMC) recently awarded Integrated Solutions for Systems (IS4S) a $95M Phase 2 contract for the Resilient-Embedded GPS/Inertial Navigation System (R-EGI) development and prototype program.

The value of the GPS SPS PS goes far beyond the specific parameters that it contains. It has a great deal of information regarding how GPS operates and ideally should be read in full (including the appendices) by everyone who works with GPS at the measurement level.

The U.S. Department of Transportation’s (DoT’s) “Complementary PNT and GPS Backup Technologies Demonstration Report” released this January has some excellent data on the relative performances of various systems in timing and positioning.

Alternative PNT from low-Earth orbit (LEO) satellites is being developed or proposed by various entities. Satelles delivers a fully operational Satellite Time and Location (STL) service to back up or augment GNSS, strengthening the resilience of critical infrastructure. This article details STL’s timing synchronization performance with different types of user equipment.
As 2020 ended, the Ligado project stood still. The FCC proceedings in the case had stagnated, while Congressional action, funds and filings flowed.
The Department of Transportation (DOT) submitted its “National Timing Resilience and Security Act: Roadmap to Implementation” report to Congress in mid-January. Following a competitive application process, demonstrations and review of 11 candidate technologies to back up GPS capabilities, the DOT concluded that “none of the systems can universally backup the positioning and navigations capabilities provided byGPS and its augmentations.” However, “all vendors demonstrated some PNT performance of value, but only one vendor, NextNav, demonstrated in all applicable use case scenarios.”

The White House issued a January 15 policy directive addressing U.S. dependence on GPS and the need to prepare for GPS disruptions. It may also signal an intent to authenticate GPS signals in the future.

Volvo Penta announced its Assisted Docking system, integrating GPS dynamic positioning, at the Consumer Electronics Show (CES). The Assisted Docking system gives the captain better control when docking a boat by automating his or her intentions, compensating for some dynamic variables, such as wind and current, and helping the vessel stay on its intended course.

Raytheon Intelligence & Space delivered its 3,000th Miniaturized Airborne GPS Receiver (MAGR) 2000-S24 system to the U.S. Air Force recently. The MAGR2K is a secure, resilient GPS receiver that enables the warfighter to navigate the battlespace with protection against interference and jamming.
