The future EGNOS is on its way

The Tender Information Package (TIP) regarding the replenishment of EGNOS Satellite Based Augmentation System (SBAS) payloads has been issued by the GSA.

The TIP complements the information contained in the Contract Notice to prepare for the EGNOS Geostationary (GEO) SBAS payload service (GEO-3) procurement process to ensure continuous EGNOS Signal In Space availability and to support the future transition from EGNOS V2 to EGNOS V3.

The EGNOS operational message is currently broadcast to  users through navigation payloads on board two GEO satellites (Inmarsat-3F2 and SES-5). These payloads relay the SBAS signals generated on the ground, allowing the users to benefit from the augmented positioning accuracy and integrity. A third EGNOS GEO satellite SBAS payload embarked on ASTRA-5B is currently under integration and should be deployed by mid-2016. Finally, a fourth GEO satellite SBAS payload on-board Inmarsat-4F2 is available for EGNOS, but only for test purposes.

According to the approaching end of life of Inmarsat 3F2 currently embarking an EGNOS payload, the need to ensure continuous EGNOS Signal In Space (SIS) availability - for which two GEO satellites are required to broadcast EGNOS message - and in view of the future transition to the second EGNOS generation (EGNOS V3) to support Dual-Frequency Multi-Constellation (DFMC) services, the GSA is planning for the replenishment of EGNOS SBAS payloads with the procurement of the GEO-3 services to be delivered from 2019.

The GEO-3 service provider will have the responsibility of relaying  the EGNOS message, to users.

For this purpose, the GEO-3 service provider will have to develop an EGNOS SBAS payload, integrate it on-board a GEO satellite, and organise the launch and positioning of the GEO on its final orbital arc allowing an EGNOS message to be broadcast over the EGNOS service area (i.e., the European Union Member States (EU-MS), Norway and Switzerland Flight Information Regions (FIR).) In parallel, the GEO-3 service provider will also have to develop two redundant RF ground stations necessary to uplink EGNOS message to the payload and to host the EGNOS Navigation Land Earth Station (NLES) equipment which will be collocated and connected to these RF ground stations.

The indicative duration of the contract is expected to be 18 years in total, which will comprise two phases: three years for the service preparation phase and fifteen years for the service provision phase. Initially the contract will be signed until the end of 2021 due to the fact that EU funds are only currently allocated for this period.  An amount corresponding to €22,000,000 (twenty two million euro) is set aside for this period.  Renewal of the contract for the full duration shall be contingent upon the allocation of EU funds to GEO-3.

Any additional information will be published in the form of "Clarification" on the freely accessible in Phase I or, in Phase II and III sent directly to Candidates respecting equal treatment principle;
GSA expects to receive the Requests to Participate by 22/01/2016 as the first step of the procurement process.
