Polytech announced an INS (inertial navigation system) specifically designed to operate with its Cobolt multi-sensor gimbals in airborne surveillance, search-and-rescue and law-enforcement applications. For geo-referencing and geo-mapping with moving maps, it is necessary to accurately define the optical line of sight. A simple GPS reference is not enough to achieve the pointing accuracy required in critical applications such as fire mapping or search and rescue. Comprising a gyro pack, 3-axis accelerometer and appropriate digital filtering, the INS kit is easily installed into an optical bench, thereby eliminating errors due to flexible mounting on the aircraft fuselage. When coupled with an external GPS, the INS system provides complete attitude and heading of the optical bench. Users can undertake target geo-location and geo-pointing operations during the flight, thereby determining the precise latitude and longitude of the observed ground area. The INS output can be coupled with a variety of moving maps and terrain models.
