    It occured to me that there is intermediate variant between printing circle of
    position on a chart and constructing them manually every time it is needed.
    What can be done instead, is for certain pair of bases every point of its
    middle perpendicular can be graduated with the angles (in degrees) at which
    this pair of bases is visible from any point of the circle with the center on
    this point and radius equal to the distance between this point and one of the
    bases.
    
    Attached PDF shows what I mean by that. Hopefully.
