    Re: Did transistors transform celestial navigation?

    I would say no.

    It could be argued that the advent of radio technology meant that a relatively cheap watch or clock in conjunction with a relatively cheap radio could replace a very expensive chronometer grade clock or watch. That meant the small-boat sailor could venture further afield (out of sight of land) with more confidence. But reliable valve (tube) radios were around for thirty years before transistor radios came along.

    The advent of integrated circuits, or silicon chip technology, meant small calculators could make sight reduction easier. But you need to know how to do the sight reduction first and that - I would maintain - is and was the biggest barrier to the use of CN by the small boat sailor. In any case, it was but a short period between the introduction of competent calculators and the introduction of the GPS receivers at resonable cost.
