GPS Signal Strength

A vehicle's location can be accurately determined if the GPS signal is sufficient. With greater signal strength comes more precise measurements. Understanding signal strength data has several benefits including location probability, problem areas with no signal strength and factors that affect signal strength.

Vehicle GPS signals can receive accurate data from satellites to determine their location. Each satellite transmits data with high precision. However signal blocking, climate conditions, large infrastructure and vehicle receivers can all affect the accuracy of the data.

GPS signal strength data gives end-users and fleet management companies a guide to the accuracy of the location of a vehicle. If location information comes with a weak signal, then tolerances can be taken into account when identifying the exact location of a vehicle. 

If no signal is being sent, the last known location identifies where an area may be blocked off from GPS, identifying it as a warning hotspot. Authorities and satellite companies can work together to reduce hot spot areas and provide more accurate GPS signal strength with future projects.
