Technologies
TerraSond's knowledge and ability to manage new technologies enables us to play a key role in the surveying and mapping industry.
We own and maintain a large suite of complex software and equipment that is necessary for executing accurate land and hydrographic surveying and mapping. The technology includes specialized tools for obtaining measurements and performing calculations on land and water that are essential for creating, editing and analyzing spatial and attribute data.
We support our staff's ability to manage new technologies by providing additional education and training. We also encourage hands-on experience to increase the conceptual understanding of geographic information systems (GIS) and their practical application for our projects.
Inertial Navigation Systems
TerraSond owns enough motion sensors to field a number of multibeam, singlebeam and side scan surveys simultaneously. There are six motion platforms available for projects that include the Seatex Seapath 200, Applanix POS/MV and CodaOctopus F180. These systems are used for multibeam surveys where heading, heave, pitch and roll are required. The systems provide RTK position and height and are compatible with dual frequency Trimble GPS receivers.
Applanix POS/MV
The POS MV maintains positioning and orientation accuracy under the most demanding conditions regardless of vessel dynamics. POS MV provides high update rate (up to 200 Hz) georeferencing and motion compensation for vessel mounted remote sensing systems. 
CodaOctopus F180
Analysis of raw motion data with Octopus iHeave allows a more accurate determination of the real heave motion experienced by a vessel, and enables the output of precise heave values for all ocean swells. 
Seatex Seapath 200
The Seapath 200 RTK provides high accuracy, real-time position, heading and attitude information by blending the best characteristics of inertial navigation and GPS RTK technologies.
