A Multi-Purpose Software GNSS Receiver for Automotive Applications

U. Haak, H-G. Buesing, P. Hecker

Abstract:	The use of GPS signals has increased in the automotive sector during the past few years. While uncoupled singlefrequency stand-alone GPS satisfies the requirements of current applications, future automotive systems especially enhancing driving safety are more demanding concerning accuracy [5] and availability of the positioning system. The IFF has developed a prototype of a highly flexible software defined GNSS receiver that can be tailored to meet needs of custom applications. The key design criterion towards the architecture of the receiver is the modularity in virtually every part of it. Its main application focus is its use as a rapid prototyping environment for emerging algorithms and deep sensor integrations. From the desired applications requirements were identified that have to be incorporated in the receiver design. The use of additional data from external sensors within the receiver routines is currently evaluated at the IFF. For the demonstrator state-of-the-art acquisition and tracking algorithms have been optimized for parallel computing on a graphics processing unit (GPU). In this paper the current implementation state of the software defined GNSS receiver is presented.
