HAPS - Coms & Observation Platform
other
HAPS, a station located on an object at an altitude of 20 to 50 km and at a specified, nominal, fixed point relative to the Earth (ITU RR Vol I 1.66a). A HAPS can be a unmanned airplane, a balloon, or an airship. All require electrical power to keep themselves and their payload functional. Since HAPS operate at much lower altitudes than satellites, it is possible to cover a small region much more effectively. Lower altitude also means much lower telecommunications link budgets (low link attenuation and hence lower power consumption) and smaller round trip delay compared to satellites. Furthermore, deploying a satellite requires significant time and monetary resources, in terms of development and launch. HAPS, on the other hand, are comparatively less expensive and are rapidly deployable. Another major difference is that a satellite, once launched, cannot be landed for maintenance, while HAPS can. Another advantage is that you can quickly try technology in the operational environment such payloads. The innovation circle is quicker: you can recover the a/c and change the sensor and launch it again.
