GPS Calculations for Arduino ( distance, bearing and destination point. )

Gps64

GPS Calculations for Arduino

I have been always frustrated from the missing double (64bit) type in Arduino world and hence the problem with properly calculating GPS distance, bearing and destination point.

This library uses Float64 & Math64 libs and also adds some fast and very fast implementations of trigonometric functions and fast and regular versions of GPS distance, bearing and destination point.

RUNNING/TESTING INSTRUCTIONS

1. download Float64 from :

https://github.com/mmoller2k/Float64

2. download Math64 from :

https://github.com/JamesGKent/Math64

note that the Math64 from mmoller2k at the time of writing (commit 254ffb9) has flaws in the atan264 function and in the asin64 function that make them unable to return negative numbers, the above fork fixes those issues.

3. download Gps64 ( and optionally Thread64) from :

https://github.com/vtomanov

4. copy the contents of repository to:

C:\Program Files (x86)\Arduino\libraries\Math64

or the local libraries folder.

• do the same for Math64, Float64, Gps64 ( and optionally for Thread64)

5. restart your arduino environment ( to pickup the new libraries)

6. select Gps64Example from file->examples->Gps64.

7. compile - upload and run - open the serial interface monitor to see the results ( the example assumes you serial monitor is initialised with 115200 if different change the following line in the example : Serial.begin(115200);

that should be all - no changes in includes etc. should be needed
