NovAtel Inc. was awarded a $142,000 (CDN) contract by Public Works & Government Services Canada for an Interoperability study on the receiver requirements for Galileo. Galileo is the European Union's state-of-the-art Global Navigation Satellite System (GNSS), which is expected to be fully operable by 2008 with up to 30 satellites orbiting the earth. This contract, sponsored in Canada by the Canadian Space Agency (CSA), focuses principally on both GPS and Galileo receiver requirements and system performance. NovAtel will study the requirements for a combined GPS/Galileo receiver. The University of Calgary, also located in Calgary, Canada, will work under a subcontract to NovAtel to analyze the performance of the system using system constellation modeling techniques.
