[citation][nom]Shodar[/nom]Someone didn't bother to read the whole article. It specifically states they used a cellphone with a GPS tracking app on it to locate the box after landing, AND it was located some 122KM from its launching point.[/citation]
i read that part, what i fail to understand is that any smartphone which you need to run an gps tracking app which is very battery demanding by itself could last that long? Basically after going more than 6 killometers away from the reach of the Cell towers max distance of signal which will place the phone in roaming, which drain the battery 3 time faster as normal, and then lose signal which make the phone work 4 times harder as normal because is always pinging for signal. Then the dense of the humidity that is usual at those altitudes which would could not be stand by a phone which is not IP54 certified and tested. Thank you.
