| Abstract: | In January of 1981 the Transportable Laser Ranging System (TLRS) developed for NASA by The University of Texas was used to
conduct a four-day test of the relative lateration technique. The test evolved making repeated measurements of six lines over
the Los Angeles basin varying in distance from 26 to 84 kilometers. Although the raw times-of-flight to the various targets
changed typically by 5 parts in 106, their line ratios varied nearly an order of magnitude less. The test suggests that the TLRS or other pulsed laser ranging
systems might be able to economically combine Lageos ranging and long baseline horizontal work to survey large areas for accumulating
crustal strain. |
