Introduction
What is it that GPS applications need to be good enough to use in a commercial environment, such as in-car navigation? Also, how does the process of interpreting GPS data actually work? In this three-part series, I will cover both topics and give you the skills you need to write a commercial-grade GPS application that works with a majority of GPS devices in the industry today.
One Powerful Sentence
This first part in the series will explore the task of interpreting raw GPS data. Fortunately, the task is simplified thanks to the National Marine Electronics Association which introduced a standard for the industry, now in use by a vast majority of GPS devices. To give developers a head start, I chose to use some Visual Studio .NET source code from my "GPS.NET Global Positioning SDK" component. (The code is stripped of features like multithreading and error handling for brevity.)
