In my pet project Run Smart With Me I decided to use GPS.NET 3.0 to handle the GPS functionality. GPS.NET is an open source project and can be found on CodePlex. My pet project will use the built in GPS device on mobile devices to track speed and distance when working out (running, cycling, skating).

In this post I will explain how I used the GPS.NET in my project.

I copied the following introduction to GPS.NET from CodePlex:

GPS.NET is a formerly commercial .NET component maintained by GeoFrameworks, LLC from 2004 to 2009. In 2009, Jon Person decided to release the full source code of GPS.NET to the public domain for the benefit of the open source development community. This version (3.0) is the latest release which had a short lifespan before being released here on CodePlex. The purpose of this framework is to deliver intuitive real-time GPS functionality with maximum laziness efficiency for all possible computers, mobile devices and NMEA-compliant GPS devices.

GPSIt is easy to think that developing an application for Windows Mobile using the built in GPS unit requires  a lot and complex code. Luckily this is not the case. You can actually have the base for a .NET Compact Framework GPS application up and running in less than 10 minutes if you choose the correct tools.

This post describes what I have found to be the easiest and fastest way to create an application that is interacting with the GPS unit in .NET Compact Framework.

Windows Mobile have created a sample for using the GPS intermediate driver from managed code and this is all you need to get started. The sample is included with the Windows Mobile 6 Professional SDK. How to use this is explained very well at the Windows Mobile Development Center: Using the GPS Intermediate Driver from Managed Code.

If you do not have any special needs you can use this directly by compiling the sample and adding the .dll as a reference in your project. If you need to customize it you can simply just add the sample source code to your project and modify/extend it where needed.

ipsGPS (Global Positioning System) is a well known technology used for tracking and navigating. Everyone that have used GPS knows that the signal is blocked when you are inside a house, in a garage or surrounded with tall buildings. IPS (Indoor Positioning System) is a technology used for positioning were GPS can not be used. The most common technologies for IPS are radio, infrared or ultrasound signals.

Lets have a quick look at the three different IPS technologies.

Radio

IPS based on radio signals can use WLAN or Wi-FI. Advantages using this: Low cost, exists a lot of places and covers large areas and could work across multiple buildings. The disadvantage is low accuracy.
