Arduino software for navigation/boats

[vtomanov]

In case someone is planing to use arduino for boat navigation and other tasks - I've decided to share open source two of the core libraries in my electric dinghy outboard project :

The GPS calculations in Gps64 may be more appealing as they are quite precise, uses 64bit floating point arithmetic ( non available on arduino) and added some trigonometric functions implemented using latest math theory discoveries in 3D graphics - as result on a arduino slow architecture in 150msec can be calculated precise distance between 2 GPS points with less then 1/2m precision (usually takes about 15sec.)

The Thread64 brings preemptive multithreading on arduino with locking structures which enables some slow operations to be done in background asinchronously based on "producer->processor-> consumer" pattern

Added full featured new example - e.g. using it you can build with arduino a marine fixed GPS for pennies similar to this model : ( all calculation and code in the example - just add the gps censor and display and send the data to the display instead of the serial - including reset of the starting point and simultaneous calculation for average speed, distance and bearing from starting point and current distance , speed and bearing from last point )

For who may need it - Logging and Motor/H-Bridge step control added as open source also :
