Setting the standard in data quality

Geotab’s unique curve-based algorithm determines which of the second-by-second GPS points should be saved and transmitted to MyGeotab.

GPS Precision

Geotab’s GO device obtains latitude and longitude information directly from the ublox GPS module, which is one of the most advanced and accurate GPS engines available today. In technical terms, vehicle position information has the precision of 0.0000256 of a degree. It is possible for anomalies to exist, as GPS signal strength could vary depending on location. Because of this, Geotab configures the ublox module in a way that pushes all data through several comprehensive accuracy tests.

Highest Level of Data Accuracy at the Lowest Amount of Data

The way in which Geotab saves data is unique. Geotab’s curve-based algorithm determines which of the second-by-second GPS points should be saved and transmitted to MyGeotab. Geotab utilizes the Ramer-Douglas-Peucker algorithm in order to reduce the number of stored GPS data points.

 

In order to give an accurate representation of the data, only the points deemed necessary are kept, which is determined through predefined allowable curve error values. The curve-based algorithm is run first on latitude vs. longitude, and then on speed vs. time. 

Geotab’s rich breadcrumb trail tracking is a patented technology that gives advanced insights into driver’s on-road behavior.

Geotab provides the highest level of data accuracy and at the lowest amount of data. Reducing the mega byte payload delivers cleaner, more accurate data. This makes reports simpler to look at and easy to edit, eliminating delays when software users need to complete multiple tasks simultaneously. Geotab performs intense testing on its firmware and devices under different driving conditions.
