Title: Return of inertial surveying — Trend or illusion?
Abstract: Inertial surveying was originally emerged and developed with the inertial navigation technology in 1960's and 1970's. Today only some marginal applications of inertial surveying still exist, e.g. gravity gradiometry, pipeline surveying, etc. With the blooming of low cost inertial sensors/systems in the past two decades, especially the evolutions of fiber optical gyro (FOG) and MEMS gyros, inertial navigation systems are no longer expensive and bulky. Therefore, inertial surveying might become feasible and popular after conquer the barriers of cost and SWaP from sensor perspective. The inherent advantages of inertial measurement, such as fully self-contained and extraordinary relative accuracy, are also attractive. It might be the time for inertial surveying to return. A typical case study, i.e. the railway track geometric irregularity surveying, is presented to show the potential of inertial sensors in the accurate surveying field, which is beyond expectation according to our traditional view of inertial navigation system.
