Global Navigation Satellite Systems Engineering, Policy, and Design
International astronomers linked observations from eight telescopes, including the the Canadian Hydrogen Intensity Mapping Experiment (CHIME), to pinpoint the location of a repeating fast radio burst (FRB), a little-understood and seldom-observed astronomical phenomenon that may hold keys to the origin of the universe. GPS played an important role in coordinating the telescopes and their milliseconds of data.

A software-driven navigation engine makes consistent, reliable navigation possible in tunnels, garages and urban canyons.
In difficult GNSS signal environments for driving—and here urban canyons, tunnels and parking structures are the standouts—GNSS performance may be severely degraded or completely denied. Inertial aiding has become the standard for ground vehicle navigation. Requirements for autonomous navigation in these circumstances will be rigorous, but those for map-matching, telematics and fleet vehicle tracking are much less so.

Septentrio and Analog Devices now combine their technology specialties, multi-frequency multi-constellation GNSS receivers and high-quality inertial measurement units (IMUs), respectively, to deliver centimeter-accurate positioning with 3D orientation (heading, pitch and roll), for applications such as automotive advanced driver assistance systems (ADAS) and industrial automation.

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.

A new European Union Agency for the Space Program (EUSPA) will succeed and expand the current European GNSS Agency (GSA), which has been managing the EU’s Galileo satellite system for 15 years.

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.
