COMPLEX NAVIGATION SYSTEM Russian patent published in 1994 - IPC

Abstract RU 2023983 C1

FIELD: aircraft instrumentation engineering. SUBSTANCE: complex navigation system was supplemented with unit of delay lines, unit of integrators and correction unit. Unit of formation of relative coordinates and angle forms relative coordinates xи= xот-xсг, zи= zот-zсг going into correction unit and unit of delay lines and relative angle α = 180°-Ψи-ϕo+n goes to one of inputs of coordinate converter where relative coordinates xo, zo are formed and transmitted to unit of delay lines and correction unit where correction signals δx, δz,(-n) also come. Signal (-n) goes also to unit of delay lines where signals are formed with delay τ″, x1= xи(t-τ), z1= zи(t-τ), x2= xo(t-τ), z2= zo(t-τ), n1= -n(t-τ) fed into correction unit. There there are formed signals (xo-xск), (zo-zск), (-Δ+n) coming into unit of integrators where signals , , are formed. With values of errors of satellite coordinate pickup and course pickup close to constant and errors of pickup of polar coordinates of reference point close to zero correction unit forms corrected relative coordinates xск, zск after termination of transient processes which are equal to real relative coordinates. EFFECT: enhanced accuracy of navigation system. 7 dwg
