Inertial Surveying Technology.
Abstract
Inertial Surveying is the process of ascertaining position and gravity field parameters from measured accelerations. Typically, the observer traverses the survey course in a vehicle such as a van or helicopter and operates instrumentation which records the vehicle's acceleration history as the survey proceeds. The instrumentation, similar to that used for inertial navigation, consists of very accurate and precise accelerometers, gyros, data recording equipment, a computer, and support electronics. The gyros provide a precise reference frame for the acceleration measurements. The computer integrates the acceleration measurements into velocity and position data to provide a real-time display during the traverse and stores information for later post-survey processing (smoothing). The general theory, operations, system description and results will be presented. (Author)
