GPS positioning time
Real-time positioning is based on the data observed by the receiver, real-time calculation of the location of the receiver antenna.
Non-real-time positioning, also known as post-processing positioning, is a method of performing positioning by post-processing the data received by the receiver.
The so-called dynamic positioning is that when the GPS positioning is performed, the position of the antenna of the receiver is considered to change during the entire observation process. That is, at the time of data processing, the position of the receiver antenna is taken as an amount that changes over time. Dynamic positioning is divided into two categories: Kinematic and Dynamic.
The so-called static positioning is that when the GPS positioning is performed, it is considered that the position of the antenna of the receiver during the entire observation process remains unchanged. That is, at the time of data processing, the position of the receiver antenna is taken as an amount that does not change with time. In the measurement, static positioning is generally used for high-precision measurement and positioning. The specific observation mode is that multiple receivers perform stationary synchronous observation on different stations, and the time ranges from minutes, hours, or even tens of hours.
