Precision Targeting Using Gps/inertial-aided Sensors
Precision weapons including miniature GPS/inertial guidance systems have become the mainstay of the DoD arsenal. These “smart” weapons can be delivered to target with unprecedented accuracy, without requiring expensive seekers for terminal guidance. GPSguided weapons are in development for gunlaunched, air-to-surface and even mortar munitions. In order for these precision weapons to be effectiv...
متن کاملContinuous High Precision Navigation Using MEMS Inertial Sensors Aided RTK GPS for Mobile Mapping Applications
A modern mobile mapping system needs a navigation component to provide accurate geo-referencing to the imaging sensors. To achieve centimetre-level positioning accuracy RTK-GPS is a natural choice. However, RTK-GPS in urban areas suffers from frequent outages and accuracy degradation. Integration of an INS and GPS can bridge the GPS outages and maintain accuracy over short time periods. This pa...
متن کاملPrecision and Reliability Incensement of Inertial Navigation System with Rotation and Redundancy
Precision and reliability are two main performance characteristic in low-cost Inertial Navigation System(INS). Increase of precision in low-cost INS without auxiliary sensors is main challenge. Bias instability leads to position drift error in inertial navigation system. In addition, fault occurrence makes the sensor reliability is decreased. Rotation of Inertial Measurement Unit(RIMU) and use ...
متن کاملTime synchronization errors in GPS-aided inertial navigation systems
The effects of time synchronization errors in a GPSaided inertial navigation system (INS) are studied in terms of the increased error covariance of the state vector. Expressions for evaluating the error covariance of the navigation state vector— given the vehicle trajectory and the model of the INS error dynamics—are derived. Two different cases are studied in some detail. The first case consid...
متن کاملVision Aided Inertial Navigation
Today GPS aided inertial navigation is widely used and well studied in any aspects. The good short term properties of inertial data are complemented by the long term stability of the GPS signal. A common approach is to use a Kalman filter for fusing GPS and inertial data to constrain the inertial sensor drift. Although this is working well in many applications there is a need to find a similar ...
