| Abstract: | There are many conversion models for GPS height conversion,such as polynomial,BP neural network and multi-quadrics fitting.Because the quasi-geoid is an irregular geometric object,every method has both advantages and disadvantages.In order to obtain a more precise and reliable analytical result,the combined model based on least square support vector machines(LSSVM)has been proposed,which has many advantages including fewer parameters and faster training process.As a result,the fitting ability is significant... |
| Keywords: | GPS height conversion least square support vector machine(LSSVM) combined model quasi-geoid fitting |
