METHOD OF ENHANCING ACCURACY OF BAROMETRIC ALTIMETER WITH THE USE OF SATELLITE POSITION LOCATING SYSTEM Russian patent published in 2008 - IPC G01S7/40

Abstract RU 2316785 C1

FIELD: navigation systems; flying vehicle control systems of high accuracy of measurement of barometric altitude.

SUBSTANCE: proposed system is used for measurement of barometric altitude H_b.alt. Proposed system is used for location of position with the aid of global system receiver. Flying vehicle plane coordinates are calculated for determination of height h_rel. of terrain relief above which flying vehicle is positioned; h_rel. is summed up with radio altimeter H_b.alt. and error of altimeter ΔH_b.alt. =H_b.alt.-(H_b.alt.+h_rel.); then, H_b.alt. is corrected by magnitude ΔH_b.alt. and result thus obtained is transmitted to barometric altitude information user.

EFFECT: enhanced accuracy of determination of barometric altitude of flying vehicle flight.
