Real Time GPS Tracking

here's the truth of the matter. There is no such thing. Anyone who uses this term is generally a salesman, and typically uniformed about technology.

You can, however use the term "Near-Real-Time" with some degree of accuracy.

That is what most suppliers really mean to say … they just sometimes shorten it to "Real Time" because it sounds better. I mean, why be accurate when you can sound good, right?

Typically They Are Talking About Updates

When a company tells you about "real time" or even near-real-time" tracking, they are usually referring to the rate at which their application updates with new locations, alarms and messages from vehicles being tracked.

GPS units on vehicles can be set to update very quickly. Typical times these days are well under one second for each new "GPS Fix".

But you can't use the information at that rate for several reason.

First, using almost any form of transmitting the data back to the user, the costs of the data transmissions would spiral out of sight.

Second, what on earth would the user DO with that much information? sway to much to store, analyze and keep track of.

After all there are 86,400 seconds each and every day … and if you had a modest size fleet of, say, 50 vehicles, do you really want to store and attempt to analyze 4,320,000 vehicle reports each and ever day? HardlRealtime GPS Vehicle Tracking a reality!

Pick an Update Rate

So the typical solution is to pick an acceptable update rate and only report every so many minutes of vehicle use. This is the industry accepted solution, and it works well … unless, of course, the report that gets "dropped" because it doesn't come at the specific time of updating is the one you actually need.
