Benefits
Results of market studies from FP5 and FP6 show that a large majority of Galileo users will
utilise the Open Service (OS) signals of Galileo, GPS and EGNOS and that the vast majority of
the market is expected to be in the LBS and automotive domains. The development of
interoperable Galileo/GPS/EGNOS mass market receivers and related core technologies is
hence important. Common features of mass market receivers are large scale production, low
unit costs, small size, low power demand, and potentially also the hybridisation capability with
other sensors and platforms. Significant effort has been devoted in FP6 to the R&D of mass
market receiver technologies, for example in the GAMMA project a single frequency L1
GALILEO/GPS/EGNOS receiver was developed. But on the other hand there are numerous
applications such as driver assistance systems which will require
multi-frequency receivers with better performance.
- The mass market receiver developed under the FP6 project GAMMA is the basis and
indispensable background know-how for the FP7 project GAMMA-A both in the team
participating and the underling core technology and background know-how.
- Further R&D activities focused on the combination of L1 GPS/EGNOS/
GALILEO signals with the E5a/L5 GPS/GALILEO and E5b GALILEO signals.
- Design, development, implementation and testing of core modules followed by
integration and testing of a complete receiver.
- The market has been analysed to refine the requirements of automotive applications for
the best commercial advantage, and an
investigation has been undertaken to establish the viability of a competitive commercial
European business based on the developed core receiver technologies.
The GAMMA-A receiver has been defined to enable a huge number of driver assistance systems which
can be realised or assisted by positioning, velocity, time or heading information from GNSS. For
instance there are emergency call systems, one-way street warning systems, navigation and
heading control systems which can be supported. The individual driver assistance systems need
a varied quantity of integrity, accuracy and availability. Especially safety critical applications
make great demands on integrity.
Driver assistance systems also have to work reliable under difficult receiving conditions (e.g. in
urban areas with strong multipath effects and shadowing of satellites). To support this key
criterion it is target-oriented to use multi-frequency GNSS-receiver.
The GAMMA-A receiver is expected to be used for automotive applications, safety
critical and search and rescue applications as well. Even premium products of applications with
less demanding requirements will make use of multi-frequency multi-standard receivers if
available for moderate prices, which will further improve the impact of this receiver technology.
