 Hi I'm Jan Van Sickle and of interest about me I am privileged to say that I worked on the first GPS surveys with the device called a micrometer which was the first civilian GPS receiver and now I'm I'm teaching on that subject GPS GNSS here at Penn State and the reason I do it frankly is because I'm trying to allow people to learn the things that they need to realize their own goals as I have been able to do in my life as a matter of fact in the past I made my living acting in New York Chicago and elsewhere so you know life takes you in different directions and I want you to be able to have the information that you need to realize your goals also I must say I teach because it's a selfish endeavor for me I'm still doing this work I'm in the industry and I like to work with people who know their business who know what they're about so it's not all altruistic
