How does Otto know the speed limits in my coverage area?
• Otto captures the signals transmitted by the Global Positioning System (GPS) satellites and measures the speed of your vehicle. This measurement, made once per second, is very accurate, up to 0.7 km/hr accuracy. Once Otto knows your speed, it compares it with the speed on the road segment that you are traveling on. Otto has a built-in map containing the speed limits on the roads in your municipality. These are based on the published data from the appropriate municipal, provincial, state or federal authorities.
