NAVISP Releases New Funding in 2023

The Ministerial Council of the European Space Agency (ESA), meeting last fall (2022), agreed to extend the Navigation Innovation and Support Program (NAVISP), the agency’s funding mechanism for new navigation solutions that go beyond the use of GNSS signals and data. That means 2023 will see the launch of new NAVISP activities.

LEO Orbit Modeling Software, SimORBIT, Allows for Accurate Lab Testing and Verification, A First

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.

Adopting Bicomplex Numbers for GNSS Meta-Signal Processing

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.
