摘要
根据我国沿海RBN-DGPS系统的工作现状,提出了从对GPS的单一依赖到多系统兼容、从只提供平面定位服务到播发高精度三位差分信息这两方面功能升级的构想,详细探讨了RBN-DGPS系统功能升级的现实需求,指明了RBN-DGPS系统在技术上实现功能升级的具体途径。
Based on the present working condition of RBN-DGPS system for Chinese coast,an idea of upgrading the functions of the system was proposed.That was from depending on GPS only to being compatible with multisystems,and from serving for horizontal positioning to broadcasting accurate three-dimensional differential information.The real needed for upgrading the system were investigated in detail.The technical approached to upgrading the system were given explicitly.
