As 2020 ended, the Ligado project stood still. The FCC proceedings in the case had stagnated, while Congressional action, funds and filings flowed.
STMicroelectronics announced that its new BPF8089-01SC6 plug-and-play RF front-end for GNSS receivers simplifies design and saves real estate by integrating the impedance-matching and electrostatic-discharge (ESD) protection circuitry typically implemented using discrete components.

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 European GNSS Agency (GSA) released a new Galileo Open Service Signal in Space Interface Control Document (OS SIS ICD), the second issue of this document geared towards GNSS receiver manufacturers. Although the modified signals are not yet broadcast by Galileo satellites, the ICD will allow GNSS receiver manufacturers to prepare for the improved signals, set for debut in 2023.

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.
