Research On The Inspection And The Application Of Gps Kenimatic Surveying Technology In The Project Of Fast

For the moment, GPS kinetic surveying has been applied in many realm of surveying successful because of the advantages such as all-weather, all-time and so on. With the development of GPS moderned, it will be more mature and more perfect, and will be applied extensively and intensively in much more kinetic areas.FAST (Five-hundred-meter Aperture Spherical Telescope) is a project designed by Chinese astronomers in order to build the biggest single aperture spherical telescope. Facing with the requirement for surveying technology, such as high precision, low speeds, high sampling, and untouched measurement etc, the study of GPS kinetic technology is more significate.In this thesis, the principle and capability of Dynamic Inspect Platform was analyzed, the measures and settings of NovAtel DL-4 plus GPS receiver and its' concerned softwares for logging, calculating were introduced. Base on these hardwares and softwares, some summarizes has been concluded in different modes of logging, different orientation styles, different measure and settings, we have contrived a series of experiments to check out the velocity and orientation precisions of GPS kinetic surveying include single station kinetic surveying, different kinetic surveying, movement baseline's kinetic surveying, and to check out the stances in the GPS single station kinetic surveying. From these experiments some quality and quantity results have been given. The datas of GPS kinetic surveying were processed with the technique of wavelet analysis and the random errors is gained in the process of low-noising. We have designed the BP NN and utilized the samples of GPS kinetic data to train the network with different train functions, different transfer functions and different quantity of nerve cells. As a result, the optimal solution was given. We have achieved 1cm precision in level and 2cm precision in height when network was expanded. We have utilized Dynamic Inspect Platform to check out the difference between GPS kinetic surveying and Total Station Instrument. In the end, the GPS difference kinetic survey with multi-base stations and one remote station was carried with 4 single frequencies of South GPS receivers and one NovAtel DL4-plus GPS receiver, the original plan for surveying the kinetic feed in FAST 500 meters prototype was brought forward depending on these.
