Last time we talked about the basics of GPS is and how it works. There are many different uses for GPS systems from farming to aviation and everything in between.
One sector that benefits heavily from GPS is ground transportation. Whether you’re getting your kids to an out-of-town soccer game or you’re moving hazardous chemicals interstate, GPS navigation systems for ground transport can make the journey faster, more economical and safer for everyone.
But there are two distinct flavors of GPS devices and your navigation needs will determine which you should choose:
- Connected - A connected GPS receiver uses its built-in connectivity (either GSM/GPRS or CDMA – GPRS is preferred and is more suitable for live tracking) to connect to a wireless provider (e.g. Sprint). This allows it to communicate information such as its location, altitude or speed to other devices or a web browser application, such as this program. An example of this is Telogis Fleet, which helps fleet owners manage multiple GPS receivers (which could be in cars, trucks, vans or even attached to people).
- Disconnected – A GPS device that is disconnected only receives signals from the free GPS satellite network, or constellation as it’s called. Information such as current location, speed, altitude and time is only available to the user of the GPS device. Unlike a connected GPS receiver it cannot send or transmit data to another device. The units are often cheaper because they do not have any built-in connectivity.
