SSRPrecise Point Positioning (PPP) and Network Real-Time Kinematic (NRTK) have historically been known as two independent precise positioning techniques due to their respective evolutions and applications. While both rely on a network of stations to estimate corrections to be broadcast to the user,...
PPP-RTK,两全其美? PPP-RTK(又名 SSR)是最新一代的 GNSS 校正服务,将接近 RTK 的精度和快速的初始化时间与 PPP 的广播特性相结合。参考网络大约每 150 公里(100 英里)就有一个站点,用于收集 GNSS 数据并计算卫星和大气校正模型。如上所述,大气校正是区域性的,因此需要比 PPP 更密集的参考网络。然后,这些...

We propose a PPP with ambiguity resolution (PPP-AR) method that combines a time-differenced carrier phase (TDCP) model, in which the characteristics of the orbit and clock are considered. Under normal communication, the PPP-AR solution is obtained by fixing satellites with small SSR product ...
