Automatic Navigation of a Long Range Rocket Vehicle

A Novel INS and Doppler Sensors Calibration Method for Long Range Underwater Vehicle Navigation

Since the drifts of Inertial Navigation System (INS) solutions are inevitable and also grow over time, a Doppler Velocity Log (DVL) is used to aid the INS to restrain its error growth. Therefore, INS/DVL integration is a common approach for Autonomous Underwater Vehicle (AUV) navigation. The parameters including the scale factor of DVL and misalignments between INS and DVL are key factors which...

Long Range Detection and Modeling of Sounding Rocket Launches

The Army Research Laboratory has been running an infrasonic array at its Blossom Point Research Facility since the summer of 1998. The infrasonic array monitors events in the 3 8 Hz window 24 hours a day/7 days a week. Interesting events are tracked down to determine the source of the infrasonic energy. This paper will discuss a series of detections that were determined to be sounding rocket la...

Computer Simulation of Long - Range Bird Navigation

Performance evaluation of temporal range registration for autonomous vehicle navigation

In this article, we evaluate the performance of an iterative registration algorithm for position estimation of Unmanned Ground Vehicles (UGVs) operating in unstructured environments. Field data obtained from trials on UGVs traversing undulating outdoor terrain is used to quantify the performance of the algorithm in producing continual position estimates. These estimates are then compared with t...
