| Abstract: | The restraint adjustment basic point choice of the GPS （ Global Positioning System） control net is applied to the construction of Luoyang hub matching reconstruction engineering in Luoyang-Zhangjiajie Electrified Railway. Then the selection of basic points, the fieldwork and data processing during GPS measurement are discussed. When the restraint adjustment of the GPS control net is cartied out, basic point choice quality has an important influence on measurement result. Furthermore, some rationale proposals of the restraint basic point choice are proposed when the GPS control net is adjusted. This can provide the reference for the engineers and technicians. |
