Brief Description of the Current Version
Program Description Screenshots Download DRAGSENS Prices DRAGSENS Order DRAGSENSDRAGSENS Geo Software is used for the exact position estimation of a towed body, sensor, camera, array or net, dragged behind a ship, aircraft or vehicle. The software allows a real-time estimation of the position of a dragged sensor based on the location of a GPS-receiver. The sensor thereby can be dragged underwater, at water or earth surface or be airborne. The software calculates the position of the sensor along the direction opposite to the course by compensation of the drift rate, the rolling and the cornering ability of the towing vehicle.
DRAGSENS receives current position data from a standard GPS string (RMC string). From these positions it averages a direction vector. Knowing the length of the tow cable, and the sensor depth, the sensor position is estimated and output in both kilometric and geographic formats. Suitable coefficients help keeping this estimation precise, considering, for example, the cable not as a straight line but as a parabolic arch.
DRAGSENS runs under Microsoft Windows and uses two independent serial ports. That also may be USB ports, controlled by a serial port driver. The input port receives the standard position data from the NMEA bus, while the output port gives the sensor position back in both geographic and kilometric format. Several strings with coordinates in different coordinate systems, date / time and additional information are broadcast on the second serial port. They all follow the NMEA standard for the RMC specifications including the checksum bit for transfer controlling.
This software at first was developed to add geo tags as an overlay with modern UTM coordinates on the footage taken by a towed underwater video camera. With suitable hardware the program delivers a video image, coming from a towed video camera, with the position as numeric overlay. It will also return the position of any towed sensor, including hydrophones, airguns, sonars or even nets. With minor modifications it could be used to estimate the position of objects on the ground during survey flights.

Accuracy check
Our products TRANSDAT, GeoDLL and BetaDLL supports transformations with the NTv2 standard BeTA2007.
The German "Arbeitsgemeinschaft der Vermessungsverwaltungen" (ADV) therefore provides a set of test data.
Comparative calculations with the test data attest an accuracy with an average deviation of only 0.02 millimeters.

TRANSDAT language files
The latest version 13.32 supports language files for the programs interface.
Since the language dependent texts are managed in external files, new languages can be added at any time by creating new language files.
Every user of the program can compile language files by himself.
