Global Navigation Satellite Systems Engineering, Policy, and Design
GPS, even when encrypted, is susceptible to spoofing and jamming and cannot be a single point of failure in critical PNT services such as military applications. Secure, resilient and assured PNT with six 9’s reliability is required, and is what ADVA and Brandywine Communications will provide through a new collaboration.

Applanix announced its Trimble AP+ Land GNSS-inertial OEM solution for accurate and robust position and orientation for georeferencing sensors and positioning vehicles in land mobile mapping applications. It enables users to accurately and efficiently track and monitor fleets, produce high-definition (HD) maps and 3D models, or act as a reference solution for advanced driver-assistance systems (ADAS) testing, even in challenging GNSS environments.

A European consortium led by the French map service provider GEOSAT will investigate how the combination of self-driving mapping cars — or autonomous mobile mapping systems (AMMS) — and artificial intelligence-based mapping software can automate the production of high-definition (HD) maps.

The joint exploitation of meta-signals received from multiple GNSS satellites, and from one or multiple antennas, can achieve high-accuracy PNT solutions in harsh propagation conditions.
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?
