Reliable and rapid ambiguity resolution (AR) is the key to fast precise point positioning
(PPP). We propose a modified partial ambiguity resolution (PAR) method, in which an …

Reliable ambiguity resolution (AR) is essential to real-time kinematic (RTK) positioning and
its applications, since incorrect ambiguity fixing can lead to largely biased positioning …

An improved method to obtain fixed integer ambiguity in GPS attitude determination is
presented. Known conditions are utilized as constraints to acquire attitude information when …

Recent research has demonstrated that the undifferenced integer ambiguities can be
recovered using products from a network solution. The standard dual-frequency PPP integer …

Reliable carrier phase positioning requires the occurrence of incorrect integer ambiguity
estimates to be limited to a maximum tolerable rate. In various simulation studies, partial …

With atmospheric corrections generated from the server, precise point positioning real-time
kinematic (PPP–RTK) can achieve high-precision solutions in a fast convergence. PPP–RTK …

Global Navigation Satellite Systems (GNSS) are used to provide accurate position,
navigation, and time (PNT) information to users in various sectors of our society including …

When GNSS measurement errors such as ionospheric delays remain large, full ambiguity
resolution (FAR) takes an unacceptably long time to fix ambiguities to integers. Partial …

Ambiguity resolution (AR) for a single receiver has been a popular topic in Global
Positioning System (GPS) recently. Ambiguity-resolution methods for precise point …

Continuous, reliable, and accurate pose estimation is the basis for perception, planning, and
control, which are parts of an autonomous vehicle system or a mobile robot system. For …
