Navigation and Electro-optic Sensor Integration Technology for Fusion of Imagery and Digital Mapping Products
نویسندگان
چکیده
Several military and commercial platforms are currently installing GPS and inertial navigation sensors concurrently with the introduction of high quality visual capabilities and digital mapping/imagery databases. This enables autonomous georegistration of sensor imagery using GPS/inertial position and attitude data. This georegistration capability enables data from digital mapping products to be automatically overlayed on the sensor imagery. In this paper, we describe the system architecture for a Navigation/Electro-Optic Sensor Integration Technology (NEOSIT) software application. The design is highly modular and based on COTS tools to facilitate integration with sensors, navigation and digital data sources already installed on different host platforms.

Inertial Navigation Electro-Optical Aiding During GPS Dropouts
Inertial navigation with low-cost IMU’s can be an acceptable sole navigation source during short periods of GPS signal dropout due to intentional or unintentional interference. However, as the dropout period continues, the inertial navigation error reach unacceptable levels. In this paper, a technique is presented where relative or absolute position estimates derived from onboard captured image...
متن کاملA Hierarchical SLAM/GPS/INS Sensor Fusion with WLFP for Flying Robo-SAR's Navigation
In this paper, we present the results of a hierarchical SLAM/GPS/INS/WLFP sensor fusion to be used in navigation system devices. Due to low quality of the inertial sensors, even a short-term GPS failure can lower the integrated navigation performance significantly. In addition, in GPS denied environments, most navigation systems need a separate assisting resource, in order to increase the avail...
