Accuracy for the Masses

A new methodology targets sub-meter GNSS accuracies in the consumer realm for applications such as augmented reality and visually impaired navigation. Recent Android RTK smartphone services in a real-time environment achieve accuracies below 50 cm. Can these be matched with PPP?

The Europeans Look at 2020

Galileo Through the Lenses of Money, Defense, Brexit and Unfortunate Events

The year of our European correspondent generally begins with two predictive events: the ESA New Year press breakfast in Paris and the EU Space Policy Conference in Brussels. It’s a tough job but somebody’s got to do it.

Washington View: U.S. Government Deals Body Blow to Its Own Military Security

The Federal Communications Commission ignored a technical standard defining radio-frequency interference. The five commissioners licensed powerful terrestrial broadcast next to the satellite band, exposing national defense and critical infrastructure to harm.

Nobody’s Fool: Spoofing Detection in a High-Precision Receiver

An on-board spoofing detection unit collects metrics from the GNSS signal processing chain and provides a real-time indication if the receiver is under spoofing attack. Test results from several spoofing scenarios are based on GNSS hardware simulations, repeaters and software-defined radios.
