GEAR DETERMINING RELATIVE POSITION OF MOVING OBJECT BY SIGNALS OF SATELLITE RADIO NAVIGATION SYSTEMS WITH HIGH ACCURACY Russian patent published in 1999 - IPC

FIELD: satellite radio navigation systems, fixing of position of one moving object relative to another object with centimeter accuracy. SUBSTANCE: system forms and tracks several potential paths of mobile receiver. Several paths whose coordinates are obtained by way of minimization of square form found by coefficients of linearized measurements of phase are generated at initial time moment. At next time moments extrapolation of potential paths is carried out, quality index is formed for each of them, several best paths are selected per each measurement moment and parameters of best path are transmitted to user. EFFECT: increased authenticity of resolution of phase ambiguity thanks to usage of additional redundancy contained in sequence of phase measurements executed at nearest time moments with maintenance of absolute stability characteristic of single-moment fixing to phase jump. 4 dwg
