Geosun Throstle is a GNSS/INS(Inertial Navigation System) integrated position and orientation system, including Throstle AV(for aviation application) and Thorstle LV(for land application), which provide high-precise time, positioning, velocity, attitude, etc, spatial reference information for various airborne and land mobile carriers.
· Throstle AV: Positioning and Orientation Solution for Airborne Vehicles
Throstle AV is is designed for the direct geo-referencing of airborne sensor data. By integrating the differential GNSS high-precise positioning technology and INS navigation technology, Throstle AV greatly improves the position and attitude information accuracy and efficiency. Throstle AV can also be used together with aviation camera, laser scanner, image sensor and LIDAR technologies.
Throstle AV provides an essential help to realize the direct geo-referencing which is a remarkable revolutionary technology in the aerial surveying and remote sensing industry. Direct Geo-referencing is to directly obtain the positioning and attitude of the sensor (also called Exterior Orientation Parameters), without the information of additional geodetic control points. The output parameters of Throstle make it possible for the data collected from sensors on the vehicles to be used directly taking the earth or local coordinate system as a reference.
