This tutorial describes how to connect to the University of Bristol's Differential GPS Server. The server serves raw GPS correction data (RTCM SC-104) to all clients connected to it. The data is intended for direct relay to a GPS device such as the Garmin modules on the jackets.
The server application runs on a machine (Pele) in the wearable computing lab. It receives dGPS correction data serially from a dGPS beacon receiver unit (CSI SBX-3) with an aerial on the roof of the Merchant Venturer's building. The strongest beacon received here is from a transmitter at Nash Point (station ID: 0689) near Cardiff. Clients connecting to the server receive the data from this unit in its raw form.
Code for the client that runs on the Bitsies is freely available. Ask a member of the wearable staff for access to it.
The dGPS server is based on a service set up by Wolfgang Rupprecht of WSRCC in Fremont, California. For more information see his website dedicated to dGPS over IP.
