Often our clients are curious about the "magic" of GPS tracking & mapping
Actually, there is a bunch of cool science behind the technology that powers navigation globally.
Recently, we were scheduled to diagnose a vehicle modem which was behaving badly. Power off/on messages, switching to internal battery messages and breadcrumb trail errors were the symptoms.
Upon inspection I immediately noticed that the main battery power switch under the cab was turned to the off position. This no power state will lead to 15 minutes of cold start data aquisition delays as the modem gets the information required for accurate global positioning.
Check out the above video at 4 minutes 54 seconds for a great explanation.
