摘　　要：结合广东省航道平高控制测量工程实例,基于GPS、精密水准和精密大地水准面模型,探讨了航道测量三维控制网的设计、数据采集、基线解算、网平差及水准平差计算的方法。结果表明,建立的高精度三维控制网能够满足技术要求,可为广东省航道安全运营提供坚实的测绘保障。Taking the Guangdong waterway project for example, an investigation based on GPS, precise leveling and Geoid model, was made on 3D control network in respects of design, data acquisition, baseline vector calculation and network adjustment, and method of leveling adjustment. The results show that the precise 3D control network can meet the technical requirements, which lays a solid foundation for Guangdong waterway system.
