This chapter presents the LRTK: long-range real-time kinematic positioning. It explores the capability of long-range single-baseline real-time kinematic positioning with multi-frequency multi-constellation observations in high-precision positioning from both theoretical and practical aspects. Regarding the big city with Shanghai-like area, Tongji real-time kinematic (TJRTK) is able to provide centimeter-level positioning service in Shanghai based on multi-frequency and multi-constellation LRTK instead of Network RTK (NRTK). The costs of the LRTK infrastructure maintenance needed by NRTK will be dramatically reduced by TJRTK.

摘要

This chapter presents the LRTK: long-range real-time kinematic positioning. It explores the capability of long-range single-baseline real-time kinematic positioning with multi-frequency multi-constellation observations in high-precision positioning from both theoretical and practical aspects. Regarding the big city with Shanghai-like area, Tongji real-time kinematic (TJRTK) is able to provide centimeter-level positioning service in Shanghai based on multi-frequency and multi-constellation LRTK instead of Network RTK (NRTK). The costs of the LRTK infrastructure maintenance needed by NRTK will be dramatically reduced by TJRTK.
