One of the advantages of GPS-based systems is their ability to adapt easily and quickly to changes in charge parameters (road classes, vehicle types, emission levels, time slots, etc.).

The Macrometer Interferometric Surveyor is a commercial GPS-based system for performing geodetic measurements.

The new GPS-based system replaces an older system originally designed by the former City of Halifax between 1984 and 1987, one the earliest real-time passenger information and transit management systems in North America.

Further, the UAV can be tracked using Automatic Gain Control or GPS-based systems.

Metro is currently in the process of replacing it with a GPS-based system as part of a system-wide radio update by 2010.

GPS-based systems, notably WAAS, allowed the expectation of the same level of positioning detail with no equipment needed at the airport.

If the primary application is not installed with redundant hardware, a single failure on the primary system controller can disable all traffic preemption functions within the entire traffic network covered by the GPS-based system.

Very good at vectoring individual aircraft efficiently (using a GPS-based system called R-NAV).

Fixed route buses use a GPS-based system manufactured by Luminator USA that periodically plays a voice-recording of the bus's location over the loudspeakers.

This was largely due to the fact that computer and GPS-based scoring systems had automated the process, and errors were almost non-existent outside of manually-assessed penalties.
