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.
