Overview
ABSTRACT
Although their ground coverage is lower, communication repeaters housed in “high-altitude or low-altitude platform stations” (HAPS/LAPS) have significant advantages over those carried by satellites in terms of reduced implementation, deployment and operating costs.
HAPS/LAPS dedicated to firefighting or territorial surveillance can also be associated with communication satellites in order to extend high-speed, low-latency wireless connectivity on a global scale.
This article describes the constraints to which HAPS and LAPS, used to provide complementary global connectivity to communication networks, will be subject, as well as the main lines of the various experiments currently underway.
Read this article from a comprehensive knowledge base, updated and supplemented with articles reviewed by scientific committees.

INTRODUCTION
Atmospheric satellites, also known as "high-altitude platforms" or HAPS, are designed to serve several purposes simultaneously.
Used to support communications and/or surveillance equipment of national or regional scope, they are a cost-effective complement to conventional communications satellites, boosting the reliability of terrestrial networks.
However, they have to contend with environmental conditions that are still relatively unknown, but are renowned for their extreme values.
