Core Package

WinFrog Seismic Core is a single-vehicle base module, which supports both position and heading devices. Two serial inputs are possible, with standard NMEA-183 message support for both position and heading data. Virtually all GPS receivers capable of real-time position output support this NMEA data format. Real-time position and navigation information for that one vehicle is updated at least once per second.

The Core package also contains basic graphics, survey line and waypoint support including the capability to load and edit information. Various seismic files such as SEGP1, P160, UK4, and Trimble SDR formats can be directly imported to a waypoint or survey line file. Actual vehicle location is displayed relative to the lines and waypoints. Position data can be recorded in various ASCII formats at user-defined intervals such as at a set time interval or at a set distance interval measured along the current survey line. The recorded data can later be downloaded for post-processing or reviewing. Recorded data can be saved in various seismic formats including SEGP1, SPS, UKOOA P1/84, UKOOA P1/90, UKOOA P2/91, UKOOA P2/94, Trimble SDR, and a QC file.

 

Mapping and Telemetry Module

The Mapping and Telemetry Module provides two additional features to the Core package. In addition to basic vehicle, line and waypoint graphics this module provides the capability to import various drawings for use as graphics backdrops. Many graphics formats are supported including: DGN, AutoCad DXF and DWG, SHP, MIF, BML, and raster formats such as BMP, GEOTIFF, TIF, and JPG.

The telemetry portion of this module supports communication between multiple systems using wireless network technology. It passes positional data between multiple systems thus enabling vehicle-tracking capabilities. The telemetry module also allows inter-vehicle file transfers so that position, line or waypoint information can be shared between systems in the field.

 

Multi-Vehicle Module

The Multi-Vehicle Module works in combination with the telemetry module described above to track multiple systems. While the telemetry module enables individual systems to send their position information, the multi-vehicle module enables the actual viewing of position data from other systems. Typically, the multi-vehicle module is only used on vehicles that actually need to record and display position data from other systems. Each system with the telemetry module can send position data, but only systems with the multi-vehicle module can display that information locally.

This communication between systems can be set up via three different methods: active token ring, static token ring and point-to-multipoint. The active token ring method works on a "token ring" principle whereby no single vehicle acts as the master of the network; instead, one vehicle initiates the passing of a token and all vehicles in range are automatically added to the network. The static token ring uses an operator-specified network membership, as does the point-to-multipoint.
