Navigation Integrity & GNSS User Authentication Receiver Development

The European Union Agency for the Space Programme (EUSPA) has issued a tender, titled "Navigation Integrity & GNSS User Authentication Receiver Development," which seeks proposals for the design, development, and testing of next-generation receivers. The procurement aims to establish two direct service contracts with a total estimated value of €8,000,000. The focus is on creating Dual-Frequency Multi-Constellation (DFMC) Satellite-Based Augmentation System (SBAS) and Hybrid Advanced Receiver Autonomous Integrity Monitoring (H-ARAIM) receivers. These receivers must implement navigation message authentication (NMA) functionalities, including Open Service Navigation Message Authentication (OSNMA), to enhance resilience against radio frequency interference (RFI).

The specification requires that the receiver prototypes attain Technology Readiness Level (TRL) 7, indicating they should be ready for flight tests in a representative environment. This development is expected to support the validation of the EUROCAE ED-259 Rev. B standard, which is significant for civil aviation as it will be the first DFMC receiver standard referenced by the European Aviation Safety Agency (EASA) and the Federal Aviation Administration (FAA) for user terminal equipment certification related to the Galileo and EGNOS systems.

Eligible applicants comprise large enterprises, specialized technology companies, and research organizations with expertise in GNSS technology and aviation systems, given the complexity and technical demands of the project, which is not suitable for small and medium enterprises (SMEs). Both single applicants and consortium arrangements are permitted; documentation supports joint bidding through templates for power of attorney and various declarations.

The application process follows a two-phase structure, requiring interested parties to first submit requests to participate by October 6, 2025, after which selected candidates will be invited to submit full tenders. The submission must be electronic, adhering to specific technical guidelines, including file type and size restrictions.

The project's overarching goal is to enhance the reliability and security of GNSS-based navigation within the civil aviation sector, paving the way for the operational use of European satellite navigation services. The tender's structure allows for a competitive assessment based on the best price-quality ratio, with no framework agreement attached, and emphasizes the importance of high technical standards in the resulting technology.

The European Union Agency for the Space Programme (EUSPA) has published a call for tenders, EUSPA/PRG/2025/CPN/0012, with TED reference 160/2025 550266-2025, titled "Navigation Integrity & GNSS User Authentication Receiver Development". This is an open call for electronic submissions. The aim of this procurement is to establish two direct service contracts for the design, development, and testing of a prototype next-generation Dual-Frequency Multi-Constellation (DFMC) Satellite-Based Augmentation System (SBAS) and Hybrid Advanced Receiver Autonomous Integrity Monitoring (H-ARAIM) receiver. The receiver will implement navigation message authentication (NMA) functionalities, including Open Service Navigation Message Authentication (OSNMA), to increase user segment resilience to radio frequency interference (RFI).

The receiver prototypes are intended to support the validation of the EUROCAE ED-259 Rev. B standard and determine the feasibility of its implementation on a representative civil aviation hardware platform. ED-259B is envisaged to be the first DFMC receiver standard referenced in EASA European Technical Standard Order (ETSO) and FAA Technical Standard Order (TSO) standards for user terminal equipment certification, with particular importance for both Galileo and EGNOS. ED-259B will be the first standard to enable the operational use by civil aviation users of Galileo Open Service (OS) and EGNOS V3.2 (DFMC).

The receiver should have a Technology Readiness Level (TRL) of 7, meaning it should be mature enough to carry out flight tests in a representative environment. It will integrate Navigation Message Authentication (NMA) functionalities for SBAS and Galileo Open Service (OS). The procedure type is a competitive procedure with negotiation. The estimated total value of the tender is 8,000,000 EUR. The contract's nature is for services, with a maximum duration of 60 months. The award method is based on the best price-quality ratio. No framework agreement is associated with this tender.

Key milestones include a TED publication date of August 22, 2025, and a deadline for receipt of requests to participate by October 6, 2025, at 23:59 Europe/Prague time.
