2022 saw the launch of a raft of new projects funded by the European Agency for the Space Program (EUSPA), applying space technologies in support of the European Union’s Green Deal. One of these projects, Space4Green, will develop a new software solution integrating Galileo OSNMA signals and Blockchain, to support trusted exchanges among users in agriculture and other sectors.

As interest in low Earth orbit (LEO) satellites grows, so has the need for accurate modeling of the environment for precise, realistic GNSS/PNT testing. This, however, is a difficult task. LEO satellites are much closer to the Earth than MEO satellites, and that means they must endure different gravitational and atmospheric impacts that are difficult to replicate in a lab.

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.

A 4D extension of complex numbers, bicomplex numbers allow for a compact representation of GNSS meta-signals with components from two different frequencies. Acquisition and tracking algorithms are obtained from the bicomplex signal representation, giving it potential for effective dual-frequency GNSS signal processing.

The Robot Plotter is a compact, fully autonomous, self-driving robot that uses RTK-GNSS positioning to place lines and other markings on a variety of ground surfaces. The machine, made by Netherlands-based Tyker Automation, sets out markings 12 to 16 times faster than traditional three- or four-person crews.
