Incidents of GNSS signals that contain phase anomalies in a way as to mimic ionospheric scintillation have been observed in the past years. Although it is challenging to differentiate an oscillator anomaly from ionospheric scintillation, their underlying physics are different and show different carrier frequency dependency. Machine learning models using extensive GNSS databases can automatically detect satellite oscillator anomaly events.

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.
The Department of Transportation Report on complementary and backup PNT technologies has good information but paints far from a complete picture. Several candidate technologies were not demonstrated, and market factors that will form an important consideration are not discussed.
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.
Spirent Communications has added premium enhancements to its GSS9000 Series GNSS simulator, doubling the update rate to run simulations at a software and hardware update rate of up to 2 kHz, improving accuracy of the simulated trajectory without compromising performance.
