Xylon captures and stores GPS information as required and configured by you. This is true low cost flexible data acquisition, the only requirements being a Pocket PC and GPS capture module. Depending upon your requirements you can use anything from a $60 GPS board to a real time kinetic system. The only requirement is that the GPS transmits in the NMEA 0183 ASC format which most do. A major feature of Xylon is the dual capture mode which allows you to capture a continuous stream of data which will plot your course, you can simultaneously capture extra readings to a separate file with codes of your choice attatched. For example, if you wish to drive along every road in a town and log every pothole requiring repair you can define a code as ?pothole? and as you drive past each hole just press the record button and a separate string with the code ?pothole? attatched is saved to file. All the while you are doing this another file is constantly capturing data to record your entire journey. This data can be processed and plotted straight on to a local map and given to a contractor who is to carry out the work. You can further refine this task by adding as many additional codes as you like to define, for instance, the depth of pothole or the repair priority level. You could use this same method of logging for recording anything from your progress in a round of golf, the position of speed cameras, the beat of a security officer, giving precise time and location information plus the recording of certain codes in key locations to ensure an inspection has taken place.
