Global Navigation Satellite Systems Engineering, Policy, and Design
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.

A 2023 lander in the moon’s Mare Crisium will carry the first GNSS receiver to that planet’s surface: the Navigation Early Investigation on Lunar surface (NEIL) receiver with software-defined radio (SDR) technology. The receiver will spring from agreements between the U.S. National Aeronautics and Space Administration (NASA), the Italian Space Agency (ASI) and the Italian firm Qascom srl.

Galileo satellites 5 and 6 (E18, E14) were declared unusable in February 2021 after reports indicating repeatable daily problems with RTK. This article explores the possible impact of deviant elliptical orbits on the performance of RTK and finds that there is no reason to expect any anomalies caused by high orbit eccentricity per se. Thus there is no reason to declare the satellites unhealthy.
