To date, we have successfully completed all of our excursions into the stratosphere with the GPS tracker TK 102-2. This device is extremely reliable and transmits GPS data with an accuracy of a few meters. All you have to do is insert a SIM card, call the number and a few seconds later you will receive the coordinates and a GoogleMaps link via SMS. The big advantage of our GPS tracker TK 102-2: If the device freezes during the flight, it can fail, but it switches itself on again after it thawed on earth, which offers additional security. Other devices cannot do this and would have to be activated manually by pressing a button.
