The Equivalent Analysis of two Adjustment Approach to GPS Control Network
Abstract
In the current rapid development of GPS technology, GPS applications in the field of measurement becomes more widespread, as the technology matures, with the corresponding research GPS data processing is received unprecedented attention. For GPS control network, improving the accuracy of baseline solution is to improve the accuracy of GPS network, but GPS control network adjustment can further improve the accuracy of the results. In this paper, GPS data processing software for research and teaching as a platform to solving baseline GPS baseline vector and vector network adjustment for the baseline study and discuss all differences and to participate in the election only independent baseline of participation equivalent adjustment This paper introduces the GPS of the network diagram design, solver and GPS network adjustment GPS baseline vector by utilizing Campass GPS data processing software research and theoretical knowledge for the experimental comparison platform, analyzes the different ways of selecting a baseline baseline level the impact of poor results, and discuss two ways of selecting the baseline equivalence.
