Precise Smartphone Positioning Based on PPP-RTK Techniques

The proliferation of smartphones in recent decades has driven advancements in technology for navigation applications. The traditional positioning methods to enable precise positioning service are precise point positioning (PPP) and real-time kinematic (RTK) techniques. But without precise corrections to the atmospheric effects, PPP has long convergence
