Communication Link Margin Design for Picosatellite operating on HAP

This paper examines the testing of Picosatellites on Highaltitude Platforms (HAPs), conducting experiments to collect data at stratosphere or near-space. This involves long-distance over hundreds of kilometers telecommunication between ground stations and HAP. This paper will suggest designing an appropriate link margin from ground to Picosatellites on HAPs, by utilizing data from actual experiments for analysis and presentation.
