At this conference, the term “high altitude platform station” (haps) has been established, defined as a telecommunications station located at an altitude of 20 to 50 km and at a specified fixed point relative to the earth. High altitude platform stations (haps) are communication facilities situated at an altitude of 17 to 30 km and at a specified fixed point relative to the earth.
The feasibility of remotely piloted aircraft performing year around missions at an altitude of 70,000 feet is determined blimp and airplane type vehicles employing solar-voltaic, microwave, or nuclear propulsion systems were considered a payload weighing 100 pounds and requiring 1000 watts of continuous power was assumed for analysis purposes.

The future of high altitude communications, arriving soon for over 20 years, people in nations around the world have researched, debated, and tested the potential of high altitude platforms for delivery of communications services to underserved areas. 12 high altitude platform stations (haps) haps are, generally, solar-powered, unmanned, remote-operated and electric motor-propelled aerial platforms held in stationary position, at altitudes between the 17 – 22 km range above the earth’s surface (stratospheric layer of the atmosphere) [7.
This thesis proposes utilizing high altitude platforms (haps) to provide affordable, efficient and robust telecommunication coverage for remote and oceanic regions. This thesis evaluates broadband wireless data technologies in combination with high altitude platform (hap) technologies it proposes a network design concept to serve as a model for future research.
High altitude platform stations (haps) are communication facilities situated at an altitude of 17 to 30 km and at a specified fixed point relative to the earth they are mostly solar-powered, unmanned, and remotely operated. Meters there is a large increase in carbon dioxide concentration over a relatively short change in altitude because convection cells are no longer present (monson and baldocchi, 2012) this distinct change occurs at what is known as the boundary layer the boundary layer should increase in altitude for the second set of measurements.
