METHOD OF FORWARD DIFFERENTIAL ERROR CORRECTION OF DETERMINING USERS COORDINATES OF MID-ORBITAL SATELLITE NAVIGATION SYSTEMS

摘要

FIELD: instrument engineering.;SUBSTANCE: invention refers to radio-engineering and can be used in transport traffic control systems for improving accuracy and continuity of determining coordinates of moving objects by means of mid-orbital satellite navigation systems (SNS) equipment. For an arbitrary point there restored and transmitted by two-dimensional spline interpolation method based on measurements of global network of stations are coordinate determining errors of the user to him to correct location. The proposed method provides increased operating stability of wide-band differential system in geomagnetic disturbance conditions, and involves ready-to-use infrastructure - global network of reference stations equipped with SNS receivers.;EFFECT: providing on wide territory the stable and high-accuracy differential correction of SNS users coordinates.
