The GSA has issued a Request for Information (RFI) regarding the replenishment of EGNOS geostationary satellites navigation payloads. The purpose of the replenishment is to ensure continuous EGNOS Signal In Space availability and to support future transition from EGNOS V2 to EGNOS V3.

Through this RFI, the GSA looks to collect information about the market in terms of availability of future navigation payloads, as well as seek opinions regarding certain aspects of the envisaged procurement, in particular in terms of feasibility of preliminary requirements.

The GSA plans to replenish the EGNOS navigation payloads starting in 2019 for a duration of 15 years. Currently, EGNOS message is broadcast to the users through navigation payloads on board 2 GEO satellites in Operation (for redundancy purpose) covering each an area which comprises latitudes from 20°N to 70°N and longitudes from 40°W to 40°E. Nominally, a third GEO navigation payload is used for test purpose and can be used in operation in case one of the two GEO navigation payloads used in operation needs to be replaced or moved to test. The payloads in operation relay the Satellite Based Augmentation System (SBAS) signals generated on ground, allowing the users to benefit from the augmented positioning accuracy and integrity (Open Service and Safety of Life Service).

Answers to the RFI should be addressed electronically to tenders@gsa.europa.eu by 31 July 2015.
