above the GALILEO sphere), enabling the use of the full Space Service Volume up to GEO stationary altitude and more for commercial applications. In this paper we will review the first results and the return of experience of the first commercial GNSS receiver embarked on the NEOSAT Platform made by Thales Alenia Space, which, according to the authors, is the first European multi-constellation (GPS+GALILEO) operational receiver that was experiencing a fully electric Orbit Rising to GEO orbit (of a duration of about 6 months), geostationary positioning and, according to the authors knowledge, first-in-the-world to provide tracking of GALILEO signals in Geostationary orbit (i.e. 26500 km – or GALILEO orbits at ~ 29300 km), where GNSS performances are strongly influenced by the availability of measurements to the GNSS Receiver.

They are past geostationary orbit, and satellites that are low on fuel will orbit this type of orbit, also known as the graveyard orbit. On Earth, both apsides are between 547.5 kilometers high and the boundary of Earths sphere of influence.

A high orbit is an orbit at a large distance from a planet. This imposes long duration orbits that intersect several times the “GNSS sphere” (the sphere of center the Earth’s center and radius equal to the semi-major axis of the GPS orbits - approx. The Geostationary Orbit: Issues of Law and Policy - Volume 73 Issue 3. To increase competitiveness, the use electric propulsion to perform or complement the transfer manoeuvres to GEO orbit is nowadays employed. Utilization of GNSS receivers on-board a Geostationary platform is becoming an attractive alternative for position and timing determination for ground operations and cost minimization.
