Prof. Dr. Kai Borre

is head of the Danish GPS Center at Aalborg University since its establishment in 1996. He is the (co)author of several textbooks, among others "Linear Algebra, Geodesy, and GPS" and "A Software-Defined GPS and Galileo Receiver; A Single-Frequency Approach". Borre has written several hundred Matlab files for processing of GPS data; they are freely available at his homepage.

Reconfigurable GNSS Receivers

The lecture gives a background of re-configurable receivers and their applications. Types of solutions – including Software Defined Radios (SDR) – are described together with requirements, list of pros and cons for each solution.

A GNSS software receiver is by no means a simple device. We concentrate on a single frequency receiver using the C/A code on L1. The lecture explains the concept of a SDR and how GNSS signals are processed all the way from antenna to the estimated position solution. The presentation underlines the main differences between software and hardware receivers. For this purpose we use a complete GPS software receiver implemented in MATLAB.

Modern software development topics include introductions to model-based development and Software Communications Architecture (SCA). An example will be given on how Simulink was used to develop a real time receiver.

A vision of future SDRs will conclude the lecture.
