Design Considerations for a Self-Contained GPS Receiver

Dave Gilman, John Lovell, Andy Stavros, John Tang, Lynn Weber

Abstract:	Building on the small, low power C/A code receiver described at the ION, Satellite Division Meeting, September 1987, Trimble has developed a hand-held, self-contained navigation system called TRIMPACK. By using available LCD display technology the power consumption has been kept under three watts, allowing up to 20 hours continuous use from internal batteries." Using an internal, or optional external antenna, the TRIMPACK displays position, time, and waypoint navigation data to the user. A -data port is also provided for use with external systems. The rugged, molded plastic housing accommodates a wide variety of outdoor applications in harsh environments. The hand-held application places unique demands on the design. Areas that must be given careful consideration include power consumption, acquisition and packaging. Each of these elements contribute to a system that provides navigation information to the user with a minimum of training.
