GPS Modernization
Jan Van Sickle, P.L.S.
Course Outline
GPS? Well, we all know the basic outline. It has been going thing for over 25 years now, originally created out of several other positioning systems, about 120 of them, back in 1973. The first launch of developmental satellites was in 1978. Operational satellites, Block II satellites began going up in 1989. Initial Operational Capability was in 1993, Full Operational Capability just two years later in 1995. This course presents some of the information about how we got from there to here.
This course includes
a multiple-choice quiz at the end, which is designed to enhance the understanding
of the course materials.

Introduction
GPS has always been a dual use system, military and civilian with the signal available with no direct user fees. Applications? GPS is used now in all of transportation, aviation, maritime, railroad, highway and mass transit. Then there’s telecommunications, surveying, law enforcement, emergency response, precision agriculture, mining, finance, scientific research, recreation, on and on. It also controls computer networks, air traffic, power grids, and the list is growing. But the system is changing, here is a bit of how and why.

Summary
The goal of a single receiver that can track all the old and new satellite signals with a significant performance improvement and without a significant cost increase while possible may be elusive. But after all, the main attraction of interoperability between new systems is the greatly increased number of satellites and signals, better satellite availability, better dilution of precision, immediate ambiguity resolution on long baselines with three-frequency data, better accuracy in urban settings, and fewer multipath worries those are some of the things we look forward to. It is beginning to look like at least some of those things are all achievable.
Quiz
Once you finish studying the above course content, you need to take a quiz to obtain the PDH credits.
