Measuring distance between two places with GPS and Arduino

As GPS receiver modules have become increasingly affordable over the last few years, it's only natural that experimenters can find various uses for them with the help of an Arduino. One useful example has been created by Instructables user "JeonLab" who demonstrates how to calculate the distance between two points as measured with the GPS receiver. 

Normally the calculations involved to make this happen would require some very accurate floating-point arithmetic, however methods that use more "large number" arithmetic have been used instead which also provide accurate results. With this project as a framework, you can create all sorts of navigational tools, make more accurate distance calculations in tracking devices and more. 

To read more about the project and formulae, visit the project Instructable page. And for more, we're on twitter and Google+, so follow us for news and product updates as well. 

Have you been reading about Arduino, but not sure where to start? Then order one our Experimenter's Kit for Arduino:

The package includes a wide variety of parts, sensors and modules including: a servo motor, lights, buttons, switches, sound, sensors, breadboard, wires and more. Furthermore a Freetronics Eleven Arduino-compatible board is included to make this an extensive hobby experimenter, inventor and starter kit. However we don't leave you alone to figure it all out, included is a great project and instruction booklet, plus access to a supporting web page and software examples. In other words - this is everything you need to get started for a fun range of electronics and Arduino related projects! So to get started or for more information and to order, check out the product page.
