Overview
The GAGARIN project is about the development of a GNSS receiver for aeronautical applications in the Russian Federation.
The project aim was to develop a GALILEO/GLONASS integrated capability in the GNSS receiver for aeronautic applications through an industrial cooperation between major receiver and antenna suppliers in Europe (respectively THALES and ERA) and in Russia (NAVIS), supported by key aeronautical Research Laboratory in Europe (DLR) and in Russia (FGUP GosNII Aeronavigatsia).
In the context of the currently existing GPS/GLONASS solutions, this dual GALILEO/GLONASS capability is necessary to consolidate adoption of GALILEO by aviation in the Russian regions.
The project set out to contribute to the development of standardised worldwide GNSS solutions including GALILEO in the pre-existing GPS and GLONASS solutions, and is paving the way to closer industrial and economical cooperation between Russia and Europe.

Results
The main results were as follows:
- Standardisation of a GPS-Galileo-GLONASS multi-constellation receiver. The GAGARIN project enabled to initiate this standardisation phase with Russian regulatory authorities.
- Innovative multi-constellation receiver autonomous integrity monitoring (RAIM) algorithms.
- Technological studies on both antenna and receiver sides are among others:
- Studies performed to assess compatibility on a triple-constellation antenna with GLONASS requirements, outlined compatibility issues between GLONASS Frequency Division Multiple Access (FDMA) L1 and satellite communication systems. Furthermore, these studies addressed design issues of an active multi-band antenna.
- Mock-up development on receiver side in order to address feasibility issues and assess potential ways to facilitate competitive industrialisation of a multi-constellation receiver. Validation in laboratory of a Galileo-GLONASS multi-constellation receiver was achieved.
Other results
Research and technological studies performed in the frame of GAGARIN paved the way to a future multi-constellation receiver product for civil aviation applications. This multi-constellation receiver has been identified as a key contributor to air traffic control modernisation enabling the following:
- coping with the expected increase of en route traffic;
- coping with the objective to significantly increase air traffic safety;
- coping with objectives of reduction of overall gas emissions and noise nuisance, by reducing the average route extension per flight and by improving the terminal approach phase precision;
- improving low visibility procedures in order to facilitate approaches and landing in bad weather conditions;
- improving the airport throughput by limiting the time spent on the airport runway and
- improving surface navigation of aircraft by providing the aircraft crew improved positional awareness through the application of visual enhancement technologies.
