It is still dark as I go out. According to the satellite tracker today is the last possibility to hunt the satellite for a long period to follow. The prediction for the next three weeks shows no passages close to Rotterdam. As I arrive at the lake it starts raining. I quickly find shelter underneath the slide at the playground and initialize the radio software. No sign of the Transit 5B-5, I think there is still not enough sunlight for the satellite to power on. The only signals I find around the satellites frequency are interferences and short bursts of air traffic as well as a periodic signal next to it. The radio communication between the airport and the aircraft is operating in the same frequency band as the satellite. I assume the periodic signal is from the ADS-B3 Signal, a surveillance technology used to track an aircraft's position.
