I've been working on the code for my Arduino GPS System over the past couple of days and am pleased to announce some new features.

The one thing which has been bugging me is that the system lacked any ability to store location data. This was annoying since if you wanted to save some coordinates you needed to write them down, and key them in manually if you wanted to visit the location later.

In order to remedy this, you can now input up to 20 way-points into memory so you don't need to write anything down. The way-points are held in the Arduino's EEPROM so they are persistent between power cycles. This means I no longer need to carry a pen and paper inside the case with my GPS receiver.

To further support using way-points, I also implemented a simple backup routine so you can save your way-points and configuration settings to a computer.

The updated code can be downloaded at the Arduino GPS System project page.
