alephito:

You are the first one to indicate that you are using an N810, so I have two things to say:

1) I have no idea if the 'GPS' code that is present is compatible with the GPS receiver of the N810. I will depend on others with an N810 to indicate if they have been successful or not.

2) I need error messages to help indicate why the program crashed -- you will need to run the program in a terminal session (i.e. python mephemeris) so that we can see what the actual Python error message is.

Note that I am presently 'moving' from one city to another, and my main computer is no longer with me -- so it may hamper my ability to help for the next little while
