GNSS Receiver Reference Design

Satellite based navigation is a rapidly growing application of satellite systems. The research of the topic is lacking "open source" hardware receivers. Our group\´s purpose is to provide one. In this paper we outline the background to the topic, motivate the need for hardware receiver research and present the functional blocks for a generic GNSS receiver. Our implementations, with their current status, are presented and the initial block-by-block functionality is presented along the signal chain from antenna to the actual navigation solution. Our future work will be the connection of the currently discrete pieces to a solid framework - a real-time GNSS receiver.
