Inaccuracy in cities has been the persistent and lingering problem for GNSS, engendering many attempts at a solution and revealing deeply embedded difficulties. This article provides an overview of the Google solution, the rollout in Android phones, and before/after results.
eMobility services that provide on-demand eBikes and eScooters rentals are fast growing alternatives to traditional transportation modalities. As they are affordable, convenient, and very green, eMobility services will continue to grow in popularity. This article presents some of the challenges and useful solutions to accurately track eBike and eScooter location in the real world.
When most were focused on the transition of power in the White House, the day before the Inauguration and the very last day in office for the outgoing party, the FCC denied a petition to stay (delay) the Ligado Networks deployment of a low-power nationwide network interfering with the GPS signal.
Compact, highly stable laser-optical clocks can improve future generations of satellite navigation systems and form the basis for new GNSS architectures.
By Inside GNSS For years, both the Executive and Congress have expressed concerns over PNT vulnerabilities and clamored for solutions. Yet little has changed. Three important reports emerged at the tail end of the old regime. As new leadership takes the helm, in which direction will it take the PNT enterprise?
