Through the frequency domain analysis of AR(10), the system dynamic characteristics is determined by the dual main poles of AR(10) model, so the single-stand GPS positioning error can be described as the 2-order Markov process.

After that,two tests were carried on to evaluate the performance of GPS absolute velocity determination in the case of a static and an airborne GPS receiver and INS(inertial navigation system) device kinematic case.

The problem of GPS single-point positioning in view point of nonlinear least square and the superiority of GA in solving GPS nonlinear optimization problems are analyzed.

Tropospheric gradient estimation model and its effect in the GPS precise point positioning

This paper analyzes the precision of static GPS Precise Point Positioning through experiments,and at the same time summerizes several problems that should be paid attention to when applying it in practice.

GPS point positioning is the current frontier of the field of GPS,searching for a suitable algorithm for rapid receiving three-dimensional coordinates of target has practical significance.
