The availability and speed of Internet connectivity in mobile devices has increased with the advent of General Packet Radio Services (GPRS). The wide bandwidth of GPRS connections makes it suitable for transmission of DGPS corrections in existing formats, however, many providers of GPRS access charge a price per kilobyte for the volume of data downloaded through the data link. This paper presents a technique for encoding differential corrections for distribution to mobile devices via the Internet that combines variable length entropy coding and keyframe-based differential coding techniques to reduce the data bandwidth required and therefore the cost of operating a DGPS system via GPRS.
