Precise Relative Positioning in MEO to support Science Missions

Precise Relative Positioning in MEO to support Science Missions

DESCRIPTION

Precise relative positioning in MEO (Medium Earth Orbit, at altitudes ranging between 2,000 and 36,000 km) exploiting GNSS is a subject that has been little explored while having high potential for enabling an interesting set of applications based on space-to-space interferometry.
Establishing accurate inter-satellite baselines based on GNSS measurements would open the door to new missions at affordable complexity and cost in the areas of Science, Lunar Exploration and Earth Observation. Examples are the imaging of the event horizon of the supermassive black hole in the centre of our galaxy, the positioning of spacecraft in Lunar orbits or aperture synthesis for Earth atmospheric sounding.
