Definition of HAPS

• Radio Regulations
• 1.66 fixed stationA station in the fixed
  service,
• 1.66A high altitude platform station
• 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.

What is Stratospheric Platform?
Unmanned large aircraft which stays stationary in
the stratosphere. Ideal for Radio Relay Stations
(HAPS) , for Remote Sensing, and many
Applications.

Concluding Remarks
?Urge development of Nature-friendly
Stratospheric Altitude Flying Vehicle (alt.
20km) as early as possible ? Need considerable
effort to reduce weight and power of mission
payload for advanced communication ? Need
continuous effort to seek attractive HAPS
applications
Need International Collaboration !
