Fundamental Elements call targets shipborne double-frequency receivers

Thursday, February 27, 2020
Large vessel

The European GNSS Agency’s (GSA) has recently launched a call for proposals under its Fundamental Elements funding mechanism targeting the development of a shipborne dual-frequency multi-constellation (DFMC) receiver that leverages the differentiators of European GNSS (EGNOS and Galileo).

The call for proposals is split into two lots, the first of which targets the development and testing of an E1/E5a double-frequency shipborne multi-constellation receiver based on the Galileo Open Service. The receiver should be compliant with International Maritime Organization (IMO) resolution MSC.233 and International Electrotechnical Commission (IEC) standard 61108-3.

The second lot in the call covers the preparation of guidelines for manufacturers for the implementation of SBAS DFMC open service and the development of firmware to process Galileo augmentation messages provided by the SBAS DFMC.

IMO Standards

The IMO recognised Galileo as part of the world wide radio navigation system (WWRNS) in 2016, allowing for its use in merchant shipping. IMO resolutions MSC.401(95) and MSC.432 put in place performance standards for multi-system shipborne radio navigation receivers.

These resolutions state that shipborne equipment should use at least two independent GNSS recognised by IMO as part of the WWRNS and should have the capacity to process augmentation data. This requirement can be fulfilled if the GNSS receiver tracks both Galileo and GPS and uses EGNOS for augmentation in dual frequency, providing differential corrections and integrity data.

In combination with the Open Service, Galileo will provide an authentication service for the navigation message (OS-NMA). Both the authentication of the navigation message and the integrity of the computed position will contribute to the concept of resilient PNT.
