<h2>Introduction</h2>

<p>This program is a proof of concept for a larger system that I plan to build. Ultimately I would like to have a system that allows users to opt in and out of letting their positions be known. The location information would be acquired through an application running on a Windows Mobile 5.0 (or later) device. Such a system has commercial applications (knowing where a delivery or service person is located) and personal applications (ex: you are heading to a friends house and the friend would like to know how far away you are). In this prototype my goal was to touch on some of the foundational technologies for the system. </p>

<p>For this proof of concept I wanted to be able to acquire the GPS information from the GPS Intermediate Driver and wanted a way to have a phone send this information either by request of the phone's owner or one of the owner's contacts. Thus the fundamental technologies used here are </p>

<ul>
<li>GPS Intermediate Driver - gets GPS information in a way that won't interfere with other GPS applications </li>

<li>MessageInterceptor - waits for location request and starts the application when one is received </li>
</ul>

<p />

<h2>Required Tools</h2>

<p>To run this code you will need to have Visual Studio 2005 installed and both the Windows Mobile 5.0 SDK and the Windows Mobile 6 Professional SDK. The 5.0 SDK is needed because I've set this project to target 5.0 devices. The code used for accessing the GPS device is part of the 6.0 SDK (though it runs just fine on 5.0 devices). I've included the compiled assembly for the GPS wrapper with my project but not the source code. To see the source code for this wrapper you must have the Windows Mobile Professional 6.0 SDK. </p>
