Constraining Network Adjustments to OPUS-RS Coordinate Observations

摘要

OPUS rapid static (OPUS-RS) was introduced to the public in August 2005 as an operational prototype. Allowing centimeter accuracy with 10-15-min observation sessions, OPUS-RS holds the promise of dramatically lessening the time needed to reference a survey to the National Spatial Reference System. (NSRS). The purpose of this paper is to compare results between networks constrained to the NSRS using multiple short OPUS-RS observation sessions and much longer OPUS observation sessions. The results of this comparison demonstrate that multiple short OPUS-RS sessions provide for significant time savings with results that agree within a centimeter of the longer OPUS sessions.
