This book was released on 2018-08-14 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The airborne laser ranging system is a multibeam short pulse laser ranging system on board an aircraft. It simultaneously measures the distances between the aircraft and six laser retroreflectors (targets) deployed on the Earth's surface. The system can interrogate over 100 targets distributed over an area of 25,000 sq, kilometers in a matter of hours. Potentially, a total of 1.3 million individual range measurements can be made in a six hour flight. The precision of these range measurements is approximately + or - 1 cm. These measurements are used in procedure which is basically an extension of trilateration techniques to derive the intersite vector between the laser ground targets. By repeating the estimation of the intersite vector, strain and strain rate errors can be estimated. These quantities are essential for crustal dynamic studies which include determination and monitoring of regional strain in the vicinity of active fault zones, land subsidence, and edifice building preceding volcanic eruptions.

Download or read book Laser Rangefinding Techniques for Helicopter Fire Control Applications Phase I Hardmounted Laser Concept written by Albert C. Cappiella and published by . This book was released on 1975 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of hardmounting a laser rangefinder to a helicopter airframe and having the pilot obtain the range to target by pointing the aircraft, was evaluated. The overall results indicate that this technique produced range errors of approximately 10% over all altitudes (300 ft. to 2500 ft.). The evaluation showed the range error to increase significantly as operational altitude decreased. This was due to small angular pointing errors translating into large horizontal miss distances when small grazing angles are incurred. Range errors of 20-25% were projected at 50-100 ft. altitudes. It was also determined that last pulse return logic produced smaller range errors than first pulse return logic.
