1. A method for compensating for sculling in a strapdown inertial navigation system, a sequence of inputs Δ

  • VB (n) being derived at times nΔ

    t from the outputs of one or more accelerometers, n being an integer and Δ

    t being a time interval, the inputs Δ

    VB (n) being compensated for sculling, the compensated outputs being obtained at times (pJ+1/2)Δ

    t and being denoted by Δ

    VBc (m,p), the method comprising the steps;

    selecting values for the set A (m,k) in the equation ##EQU32## k taking on values from 0 to K-1, m being equal to 1,j taking on values from 1 to J, J being equal to or greater than 2, p being an integer;

    determining the value of Δ

    VBc (m,p) for each value of p.
