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.
China has released four national technical standards for the BeiDou Navigation Satellite System (BDS), according to the China Satellite Navigation Office, for fields of the data format, map application, ground-based augmentation system and atomic clock.

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.
The European Commission awarded two contracts for 12 satellites — 6 satellites each — for a total of EUR €1.47 billion to ThalesAleniaSpace (Italy) and Airbus Defence & Space (Germany) following an “open competition.”

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.”
