Acceleration of PPP Integer Ambiguity Resolution When Emploing Ionospheric Delays

Popis výsledku v původním jazyce

Precise Point Positioning (PPP) is a powerful method for GNSS data processing, when observations from only one receiver are utilized. Since any systematic error is not eliminated by between-stations differencing, introduced precise products and models are crucial for precise positioning. While precise satellite orbits and clocks corrections are essential for traditional float PPP, satellite phase biases are required for integer ambiguity resolution (PPP-AR). When considering also local ionospheric and tropospheric parameters, the integer ambiguity resolution is achievable very fast, which helps to reduce the initial convergence significantly. When exploiting such precise atmospheric corrections, the solution can be considered an alternative for the popular Real Time Kinematic (RTK) method. Therefore, the solution is usually abbreviated by PPP-RTK. We processed daily GNSS data from EUREF Permanent Network (EPN) using PPP, PPP-AR, and PPP-RTK. The tropospheric delay was not introduced as a product but e
