Assessment of technology requirements associated with spaceborne laser ranging. Volume 1: Mission analysis, identification of representative point positioning experiment and definition of associated mission characteristics and instrument performance needs
Abstract
An experiment which monitors recent crustal movements along active tectonic faults is discussed. Nearly real time orbit prediction with meter accuracy is required for laser system acquisition and pointing. Orbital fits with decimeter rms deviations are needed over the test area to derive baseline information with centimeter precision from short arcs. Laser measurement accuracy within 3 cm and epoch time precision within 0.0000015 sec are required. Minimum elevation error should be 20 deg.
