    Dear Modris,

    Check it here: https://naif.jpl.nasa.gov/pub/naif/generic_kernels/spk/planets/

    I am not sure, that you really need the de431.bsp for your application (it is HUGE!), the de421.bsp will suffice, if your program accepts it.
    (less planetary bodies and shorter time range, but well enough for sextant calibration.)

    Best regards:

    Tibor
