| Abstract: | This paper explores the extension of current integrity monitoring methods for road navigation, specifically Real-time Kinematic Positioning (RTK). The paper examines a key issue for extending current integrity monitoring methods for RTK: guaranteeing a high successful rate of fixing ambiguity resolution. The paper proposes a real-time critical value algorithm based on failure rate and variance matrix to help find the right choice of critical value in RTK applications. Additionally, a partial ambiguity fixing (PAF) model based on the LAMBDA algorithm is used to improve success rates by resolving partial ambiguities in the presence of multipath or unaccounted-for atmospheric delays. Results demonstrate that the added PAF algorithm can maintain a higher success rate in resolving ambiguities while reducing the computation burden. |
