Project Overview
GAWAIN`s main objective is to develop an integrated GNSS/UMTS receiver, which provides seamless indoor/outdoor NavCom using GPS/Galileo and 3G/UMTS.
The multitude of mobile communication standards (UMTS WCDMA, CDMA 2000, GSM, GPRS, EDGE, IS 95 etc.), currently emerging, call for increased flexibility of the hardware.

The same applies for the next generation of satellite navigation systems; GPS is undergoing a modernization phase (GPS III) and the number of frequencies available to civil
users is increased from one to three. The definition of Galileo foresees at least four different frequencies, some of which overlap with GPS. All of these new signal structures
tend to have an increased bandwidth compared to the older standards.
The targeted applications such as combined Galileo/GPS and UMTS processing and new, advanced and highly demanding processing techniques, like indoor positioning continuously crave more processing power.
The objective of GAWAIN, namely to provide a solution that combines communication with satellite navigation therefore must call for a special solution.
The goal of GAWAIN may only be reached with the capability to completely configure the processor through software ('Software defined Radio') and the 'ReConfigurable Processor' (RCP) approach. Thus, another objective here is to develop algorithms able to deal with these requirements.
