In later lectures we will discuss more detailed description of these errors..3 Error Modeling Example Accelerometers f i = a (I M a ) i nl a w a (3) 1
2 Gyroscopes ω i = g (I M g ) ω i G g i w g (4).4 Pos, Vel, Force and Angular Rate Errors Position error Velocity error Specific force errors δ r γ β = r γ β ˆ r γ β (5) δ v γ β = v γ β ˆ v γ β (6) δ i = i ˆ i (7) Angular rate errors e i = i ˆ i = δ i (8) δ ω i = ω i ˆ ω i (9) e ω i = ω i ˆ ω i = δ ω i (10).5 ECEF Error Mechanization Recall δ ψ e Ω e ie e δ v e = [ C ˆe e δ r ˆ f i ] 2Ωe 2g 0( ˆL ) ˆ r e ie e res e ( ˆL e (ˆ r e ) ˆ r e e 2 e )T δ ψ e e δ v e e e I δ r e e 0 Ĉe ( ) Ĉe 0 ef i 0 0 e ω i (11).6 Errors After Caliration In reality there will e error terms in the sensor that can not e calirated. These terms may e estimated. The error in the estimation of these terms may e expressed as e i = i ˆ i = F va δ x a ς a (12) e ω i = ω i ˆ ω i = F ψg δ x g ς g (13) These terms represent the difference etween what we estimate the errors in the sensors to e (either through caliration or online estimation) and the actual errors in the sensor..7 Error Terms The matrics F va and F ψg, depend on the needed level of complexity in modeling the errors. For example if we only model iases, e.g., δ x a = δ a, then F va = I. If more error terms are modeled, then most likely, we will end up with non-linear equations, and therefore linearization is necessary..8 Error Modeling δ x a = F aa δ x a w a (14) δ x g = F gg δ x g w g (15) The matrics F aa and F gg are specific to accelerometers and the gyroscopes and there specific configuration within the IMU..9 2
