In order to keep in touch with our glider and get all the data from the flight, we have to establish a connection to the ground. The data consist of position and flight path information, as is also the case for public transportation planes.
The rocket, wherein its cone the glider is mounted, is capable to reach an altitude of around 80 km. This means we The rocket, wherein its cone the glider is mounted, is capable to reach an altitude of around 80 km. That means we have to transmit the data all over a distance of around 100 km, cause of the parabolic flight behavior. To do so, we plan to use an array of so-called “microstrip-patch-antennas”, which are also used in maritime radar systems. Those are powered by amplifiers with a maximum output power of 4 watt, which is 40 times more power than in your mobile phone. So stay tuned to see the first range tests with our first revision of the amplifier PCBs and antenna System.
