Switching on the GPS with anticipation
When you switch on the GPS it takes a little time to find the position. At that very moment, the position mistake is very high, 100 meters, 200 meters or even more. The heigh precision is, as well, very poor. As new satellites are found, the mistake gets lower, until +/- 3-7 meters aproximatelly.
If we take this into account, it is very important not to start recording until we have reached an acceptable working precision.
