How Accurate is GPS Speed in a Vehicle Tracking System?
Updated: Nov 7, 2021
On July 3, 1886, mechanical engineer Karl Benz drove the first automobile in Mannheim, Germany, reaching a top speed of 16 km/h (10 mph). Today the fastest car Hennessey Venom GT can reach speeds up-to 270 mph. The reason speed is monitored is not just for setting a record but in practicality it is used by fleet companies for ensure road/ consignment safety along with enhancing green driving habits.
According to Richard Langley, professor of geodesy and precision navigation at the University of New Brunswick, GPS speed is more accurate than most of the speedometers.
GPS Speed Accuracy :
As long as there is clean line of sight of the GPS antenna, which is usually called as "open to sky" the accuracy of GPS speed is 0.2 of a kilometre per hour.
At Traxroot connect we can also set up map layers with preset speed values at different Geo fenced areas making it convenient to differentiate working speed values in different areas for example urban city areas and freeways or highways. Our devices also have in cabin alerts which can be triggered when the driver exceeds the allowable speed.

The way GPS speed works in fleet management, is to track, manage and maintain your fleet and been one of the key parameters for fleet safety, speed of a vehicle is constantly monitored. A preassigned speed value as per the vehicle's industry of operation is set and when the speed values exceeds the working values, alerts via push notification or email/ SMS will be triggered. Monitoring the speed not only reduces accidents but also saves the lives of the driver and the public.
