PPP-RTK

PPP-RTK is a technology that combines PPP positioning and RTK positioning. PPP-RTK is a high-precision positioning technology based on State Domain (SSR). By comprehensively estimating and modeling base station data, a set of state correction variables including satellite clock errors, orbit errors, regional ionospheric errors, etc. are generated and sent to mobile stations for position calculation.
The advantage of PPP-RTK technology lies in its integration of the advantages of PPP and RTK. Compared with PPP positioning, PPP-RTK technology has higher real-time performance and can provide more accurate positioning results in rapidly changing environments. Compared with RTK positioning, PPP-RTK technology does not require direct acquisition of benchmark station data, making it more flexible and convenient.
