An assessment of GPS receivers for navigation and a survey of their applications, performance, physical characteristics and trends

Summary form only given, as follows. The development and implementation of the GPS (Global Positioning System) satellite constellation has resulted in widespread use of GPS receivers in civil applications. Although the system is not yet fully operational, there are already more than 60 manufacturers of GPS user equipment offering over 150 different models to the marketplace. The author has surveyed developments in GPS receivers, comparing performance, as well as their electrical, physical, and data interface characteristics. Future trends in receiver capabilities, performance, and price have also been examined, including an assessment of user population growth in various markets and applications.<>
