Also the paper explores the implementation method of broadband quadrifilar helix antennas by theoretical research and electromagnetic model analysis. We achieve the goal that VSWR is less than

Under the condition of the existence of multiple constellations, the number of observable satellite number will increase sharply in single epoch. Because of the limitation of computing source, too much redundant information brought by redundant satellites can not gre

However, with increasing distance between the rover and the reference receivers, the decorrelation of the atmospheric errors will make it more and more difficult to fix the ambiguities quickly. Recent studies show that PPP using the raw observables by estimating the ionospheric

Firstly, the basic principle of geometry orbit determination is introduced and the observation equation is linearized in this paper. Secondly, The GDOP value is parameterized by using orthogonal trigonometric functions.
