Distances and bearings between points

[StephenG1CMZ]

Dale,

That work sounds very interesting.

I have previously developed client software for modem applications - back in the days when modems were real boxes doing dial-up. And a radio telemetry protocol designed for aerospace... Vehicles.

So the thought that I might one day be using these distance calculations together with GPS or AIS decoding has crossed my mind - especially since I live within VHF range of the coast.

When I first started to look into the HP Prime for on-Android/on-calculator compiling, I was thinking one might be able to plug a GPS/AIS into a datastreamer into a HP Prime...but I believe the datastreamer is not that flexible.

As for using existing navigational devices - I find it astonishing that my Google Maps is so good at drawing maps, but abysmal at displaying your latitude and longitude - and distance from a repeater.

(If anyone needs software to their custom requirements - mail me).
