Reliable touch detection provides extremely high sensitivity with very low capacitance measurement resolution, offering a highly accurate and robust solution.

The first Astronomer Royal, John Flamsteed, compiled the most accurate star catalogue of his day as part of this attempt (though the solution was eventually provided by John Harrison, a clock maker who designed a timepiece that was robust enough to withstand the rigours of sea travel, and was thus able to substitute for the stars in the relevant calculations).

The simplest solution is a good golf-specific GPS that will show the course in detail and provide accurate yardages to both the green and to trouble and lay-up locations.

His realization was that the solution wouldn't come from improved astronomical readings, as many thinkers believed, but from an extremely accurate clock that could tell the time of the home port while at sea.
