Global Navigation Satellite Systems Engineering, Policy, and Design
In early December, Qualcomm made its annual announcement of a new chip for phones and wearables in the coming year. Qualcomm’s flagship system-on-chip will power a range of devices launching in 2020, with lots of new and exciting (to smartphone addicts) capabilities; just not much — make that nothing — new in satellite-based navigation derivatives.

The European GNSS Agency (GSA) awarded a contract for the development of the Galileo-based TIming Receiver for CriticAl INfrastructure Robustness (GIANO) to Thales Alenia Space, for resistance against interference, jamming and spoofing.

Reducing the number of GPS receivers installed or carried while tapping multiple PNT sources.
Prototyping and beta testing are techniques closely associated with Silicon Valley, the innovation engine admired around the world and, in particular, inside the Pentagon. Simply introducing a new idea has been known to take years in these halls; witness the long introductory saga of GPS itself in the 1970s.

A version of the NeQuick G ionospheric model algorithm to help single-frequency receivers to estimate and correct for the ionospheric propagation delay is now available for download from the Galileo Service Center (GSC) website). Using a new coding approach, this version is the result of intensive effort by engineers at the EU’s Joint Research Centre.

In a letter made public late Friday, the point person for all federal agency use of frequencies told commercial spectrum regulators his agency could not support approval of Ligado Networks’ request to use satellite frequencies for a terrestrial wireless network.

Calling all automotive engineers — and anyone involved in designing or promulgating the fast-oncoming world of autonomous driving.
For driverless vehicles, current GNSS meter-level positioning accuracy still serves for lane-level detection. But hazardous misleading information poses a serious, disruptive and critical safety concern.

An innovative positioning engine based on a safety-oriented paradigm uses a dual-frequency GNSS receiver, automotive cameras, accurate maps, low-cost inertial sensors and vehicle odometry. The real-time integrity layer bounds the error of each estimated value with a confidence level for safe navigation.

This summer, French railway company SNCF performed successful tests of an autonomous train, using Galileo-enabled receivers. The vehicle ran a distance of four kilometers with the help of remote control. SNCF intends to develop its own prototypes of autonomous freight and passenger trains by 2023.
