Development of Methodology for Determining Earth Work Volume Using Combined Static and Kinematic GPS Observations
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 4
Abstract
Computing earthwork volumes is a necessary activity for nearly all construction projects and is often accomplished as a part of route surveying, especially for roads, Dredging and highways. If the area of the cross section at each station is known, then multiply that average end area by the known horizontal distance between the stations to determine the volume of cut. We present the results of precise static and kinematic point-positioning solutions obtained in post-processing, with a recursive Kalman filter estimator. The observations are dual frequency GPS carrier phase and pseudo-range, treated as two distinct data types, each with its own measurement equations. The receiver data is double differenced between satellites, to eliminate the receiver clock, and processed using precise satellite ephemerides and clock corrections. While estimating receiver coordinates, ionosphere-free carrier phase Lc biases, and tropospheric refraction model errors were treated accordingly. The motivation has been to show the possibility of the application of GPS in Topographical Survey and it associated accuracy. The method is fast, accurate and data was acquired using Trimble 4000SSI GPS Receiver and processed using Trimble Geomatics office.. The results indicate a precision at the level of a few centimeters, for static solutions, and below one decimeter, in kinematic mode.
