Abstract Modern quantum technologies have matured such that they can now be used in space applications, e.g., long‐distance communication. Here, the design of a compact true single photon source is presented enhance secure data rates satellite‐based key distribution scenarios compared to conventional laser‐based light sources. The fluorescent color center hexagonal boron nitride. emitter off‐resonantly excited by diode laser and directly coupled an integrated photonic processor routes...

The chair of space technology Technische Universität Berlin has a long heritage designing, manufacturing and operating small satellites. Starting with the launch TUBSATA in 1991 up to TUBIN 2021, total 27 satellites range 375 g 56 kg were successfully developed. To date, 20 these satellite remain operational are contacted on regular basis. utilized frequencies p band, s band x ranges. accommodate simultaneous operation missions, primary ground station at is equipped set different antennas...
TUBIN is a microsatellite mission tasked with the detection of high-temperature events from low-Earth orbit. Launched in June 2021, it employs sensor suite consisting two microbolometer focal plane arrays sensitive thermal infrared range electromagnetic spectrum as well complementary camera visible range. Thermal anomalies are detected within readings sensors and their localization assisted by camera. The were calibrated on-ground. However, to account for limitations ground calibration setup...
The TUBIN spacecraft launched in June 2021 is tasked with the detection of high-temperature events. To this end, it employs two microbolometer focal plane arrays and a complementary sensor sensitive visible range. Using simulated data, fire algorithm was developed. Within first 18 months mission operations, several hundred scenes containing wildfires other events were captured. detected can be categorized into volcanic features, vegetation fires artificial such as gas flares. Fire maps...
Flight dynamics is a topic often overlooked by operators of small satellites without propulsion systems, as two-line elements (TLE) are easily accessible and accurate enough for most ground segment needs. However, the advent cheap miniaturized global navigation satellite system (GNSS) receivers laser retroreflectors well modern, easy-to-use, open-source software tools have made it easier to accurately determine an orbit or identify spacecraft in swarm, which helps with improving space...
