Global Navigation Satellite Systems Engineering, Policy, and Design
GMV and Lockheed Martin have plans to develop a global satellite based augmentation system (SBAS), changing the model for how navigation and precise point positioning (PPP) services are received.

The SAGAIE network was deployed in West-Africa in 2013 to assess the feasibility of an equatorial for ASECNA SBAS by studying ionospheric scintillation. This study of the network’s measurements, taken between 2013 and 2016, analyzes the characteristics of the scintillation recorded by five receivers that cover Sub-Saharan West-Africa.

The European Geostationary Navigation Overlay Service (EGNOS) will soon launch a new maritime solution that will make legacy and costly coastal ground-based augmentation systems redundant. Meanwhile, the next generation EGNOS V3, featuring dual-frequency, multi-constellation (DFMC) services, is set to come online by 2028, once GPS L5 is declared operational.

The European Union Agency for the Space Programme (EUSPA) has published an online interactive world map providing information about augmentation service providers that support Galileo. Clicking over each country shows the names of the Galileo-ready providers along with the name of the service, type of service and coverage.

Using in situ sensors, GNSS corrections and satellite remote sensing, it is possible to obtain information on soil anomalies, enabling farmers to take corrective actions in the field. This information is given through a pre-set field map which identifies areas needing a specific treatment, leading farmers to an improved cost-benefit ration for their agricultural crops.

Iridium Communications Inc. made a strategic investment in DDK Positioning (DDK), an Aberdeen, Scotland-based provider of enhanced GNSS accuracy solutions. DDK uses the Iridium network, provided by a low Earth orbit (LEO) constellation, to provide global precision positioning services that can augment GNSS accuracy

In May the former European GNSS Agency (GSA) officially rechristened itself as the European Union Agency for the Space Programme (EUSPA), marking the start of a new era for the EU space effort. Building on the legacy of the GSA, EUSPA will take on more responsibilities to create opportunities for EU citizens and the economy.

A new tome — make that two new tomes — join the bookshelf of essential and authoritative references for GNSS users, while widening the umbrella a good deal to cover all PNT technologies, their sensors and their integrations. Edited by four leading lights of the community and assistant-edited by two more, its list of authors rounds up another 131 of the “usual suspects,” the names that are seen repeatedly in the presentations at technical conference and on their organizing boards. In every one of 64 subject matters, the author(s) is/are recognized experts, in many cases the recognized expert, on the material.
