METHOD AND DEVICE FOR IMPROVING POSITIONAL ACCURACY WITH MEASUREMENTS BY RADIO ENGINEERING METHOD

摘要

FIELD: measuring technology. ^ SUBSTANCE: invention refers to method and device for greater positional accuracy of a terminal with using of a measurement collection. The technical effect is ensured by obtaining an initial position estimation and correction thereof by means of measurements. The correction is enabled by deriving a measurement vector from the initial position estimation. Observation matrixes are formed for measurements. Weight factor matrixes are evaluated. The measurement vector provides a basis to derive a correction vector that is used to correct the initial position estimations. ^ EFFECT: higher accuracy of the initial position estimation for the wireless terminal. ^ 30 cl, 13 dwg, 1 tbl
