PPP-RTK 사용자 정확도 최적화를 위한 보정 메시지 스케줄링 기법 설계

Abstract

SSR corrections used in precise point positioning-real-time kinematic (PPP-RTK) systems enable efficient bandwidth utilization by decomposing the corrections into separate components. To optimize PPP-RTK user positioning performance, an effective scheduling strategy is required to minimize temporal errors while meeting bandwidth constraints. This paper derives the optimal update intervals for each PPP-RTK correction component by analyzing their temporal error characteristics. Based on these optimal intervals, we develop a correction message scheduler that mitigates positioning performance degradation under bandwidth-limited conditions.
