Benefits of technology

This technology described by this patents allows users to easily switch from one location (base) network into another while still receiving accurate timing signals or observations on their own devices. It also uses different techniques such as radio frequency triangulation, cellular networks with multiple antennas, and satellite systems like GLONASS to improve accuracy. Overall, this technology helps optimize communication services more efficiently across geographic areas.

Problems solved by technology

This patented technical problem addressed by this patents relates to how users often switch between different types of communication networks during their usage while still providing accurate geolocation results at millimeters levels.

Abstract

The invention provides an RTK positioning method and device, a GNSS positioning chip, an RTK positioning module, a mobile terminal and a computer readable storage medium. According to the method, after RTK positioning at the current moment is completed by using base station data before switching, a high-precision positioning result can be quickly output, seamless switching of the base stations is realized, and then a single-difference ambiguity floating point solution at the current moment is compensated by using observation data of new and old base stations to obtain a floating point calculation result at the current moment. The resolving result can be used during RTK positioning resolving at the next moment, the single-difference ambiguity convergence result obtained in the original RTK positioning resolving process is fully utilized, and continuous output of high-precision positioning results above centimeter level can be achieved after base station switching without convergence again. For the user, the switching of the base station does not influence the continuous provision of the positioning result at all.
