The invention is a method and apparatus for compensating for sculling in a strapdown inertial navigation system. The method operates on a sequence of inputs .DELTA.V B(n) derived at times n.DELTA.t from the outputs of one or more accelerometers. Separately compensated quantities .DELTA.V Bc(m,p) calculated at times (pJ+1/2).DELTA.t for M values of m are obtained by summing A(m,k).DELTA.V B(pJ-j-k) over k from 0 to K-1 and over j from 0 to J-1 where the constants A(m,k) are chosen to minimize sculling error in the individual .DELTA.V Nc(m,p) quantities where d .DELTA.V Nc(m,p) is the representation of .DELTA.V Bc(m,p) in the navigation frame of reference. The final compensated quantity .DELTA.V Bc(p) is obtained by summing B(m).DELTA.V Bc(mp) over m where the constants B(m) are chosen to minimize sculling error in .DELTA.V Nc(p) where .DELTA.V Nc(p) is the representation of .DELTA.V Bc(p) in the navigation frame of reference.
