Nice powerpoint I wasn't really sure of how GPS worked before your presentation, it was very informative. Nice job!

Your Power Point was very well done.  The background was a perfect choice--your transitions were good and you had some nice graphics.  The information was well done with nice explanation of how a GPS works and you had a nice variety of applications shown.  Very interesting! 

Good job! I liked your powerpoint because it was to the point and very informative! Thanks for teaching me about GPS!

You did a good job! I liked the presentation and I learned a lot more about GPS systems.
