New navigation missions for enhanced satnav and Earth mapping

ESA’s Navigation Directorate – already the design architect of the Galileo satellite navigation system, Europe’s largest satellite constellation – is reaching out to European industry as it plans the development and in-orbit validation of future ‘positioning, navigation and timing’ (PNT) missions into novel orbits.

GENESIS will also allow the assessment of several new navigation related technologies and precise orbit determination strategies of potential interest in future GNSS and Earth observation satellites.

Intended as a small, low-cost mission, GENESIS will orbit in lower-level MEO, approximately 6000 km up, which allows to provide an excellent simultaneous operation of all onboard geodetic techniques and ensure the possibility of simultaneous observation at intercontinental distance of VLBI ground stations, an essential point which will also allow the provision of closer links between the Earth and the Celestial reference frames, which provides multiple scientific and application benefits.

Beyond its very high scientific and navigation techniques interest, the results obtained thanks to the GENESIS mission will result, in turn, into a major increase on the overall accuracy, stability and availability of geodetic datasets, which will no doubt stimulate the creation of a plethora of novel or enhanced applications.
