Four Things You Should Know About GPS Data Loggers

Posted on

It's important that users fully understand what a GPS data logger is and how it works in order to make the most of this highly useful and convenient device.

The following are four things you should know about GPS data loggers if you're thinking of purchasing such a device:

The main function of GPS data loggers is to periodically log the GPS device's location.

While a GPS device merely shows the user's location at any given moment, a GPS data logger will record that location and save the location along with the time so that this data can be looked up later.

GPS data loggers are therefore useful at automatically tracking a user's movements over time and keeping a record of where the user has been in the past. 

A GPS data logger will typically work through using either an internal flashcard accessed via USB or memory card slot.

Data loggers must work using some sort of data storage feature. Generally speaking, there are two possibilities for ways in which a data logger will store location data.

One common way that data loggers are designed to record data is with an internal flashcard. With this option, the user must plug the device into their USB connection in order to access the data.

Another common way a GPS data logger is designed is to use a memory card. With a memory card, the entire memory card can be removed and inserted into a computer for data to be accessed. 

GPS data loggers will create a record of past locations in the form of a GPX, NMEA, or KML file.

It's important that those on the market for a GPS data logger understand the different file types that a data logger can produce. You need to have a computer or other device available to you that will be able to read the produced file type in order for the device to be useful to you. 

The most common file types produced by GPS data loggers are GPS, NMEA, or KML files. You need to match your data logger up with the file types your computer is capable of reading. 

Unlike an active GPS tracker, a GPS data logger doesn't require a cell signal.

One big advantage that GPS data loggers offer is that they don't need a cellular signal in order to work. This makes them less expensive to use than active GPS trackers.
