EUSPA seeks proposals for a Galileo HAS enabled Space receiver

Submission deadline 30/01/2026 - 23:59

Find all the details and requirements here: www.euspa.europa.eu/opportunitie...
Fundamental Elements - Galileo HAS enabled Space receiver. Submission deadline is 30 January 2026 - 23:59. The high-level objective of the call is the development of a GNSS receiver for LEO (mega-constellation) satellites in the 50 — 500 kg class and space applications with Precise Point Positioning (PPP) capability based on Galileo’s E6 High Accuracy Service, which provides real-time positioning accuracy at least in a range of few decimetres.

(a) Comparison of the ERI fault model (rectangles) and the 7-d aftershocks by JMA (dots). The yellow star represents the epicentre. Note that this study does not employ the fault planes with grey text (NT7 and NT10). (b) Location map of the NOWPHAS wave gauges. (c) Location of GEONET stations. (d) SAR scene coverage of each path. The red and blue rectangles denote ascending and descending orbits, respectively.

Same with me; aviation (GNSS-based aircraft navigation and landing systems) this year was the turn of the USA to host, and it turned into an online only conference as nobody wanted to risk attending in person.
