Arcas integrates a Rockwell Jupiter 12 channel GPS receiver, an RDS 3000 differential correction receiver, a serial interface and a rechargeable battery in an attractive hand portable enclosure. The unit is intended for connection to a portable PC via a single RS232 serial link. Differentially corrected position, time/date and status information is available to the PC at one second intervals. The unit is intended for use with software to record positions along with other information e.g. inventory control, mapping etc.
The Focus FM premium service provides 1 m (2drms) accuracy. Extensive testing has indicated that this level of performance is achieved even in difficult urban environments. A 10m (2drms) service is also available from Focus FM at lower cost.
The board is supplied with Field Geometry Tool (FGT) software for mapping applications. The software consists of an intuitive graphical interface providing four main functions.
Logging: Differentially corrected positions and time of day are recorded on disk at one second intervals. A real time map is displayed to confirm correct operation.
Differential control: Allows control of the differential receiver to select specific transmitters, frequency scanning or limited tuning ranges. This provides improved performance in difficult reception areas and urban environments.
File Utilities: Allow recorded data files to be displayed and exported in a format suitable for direct input into ArcInfo and GWS
POI entry: Allows the location and description of Points of Interest to be recorded.
The FGT application continuously displays time and position as well as status information. Audible and visible warning is provided if differentially corrected position is not available.
