The task of providing high-quality communication and high-speed Internet access anywhere on Earth is nowadays of utmost importance in successful development of the public and private digital services. The paper presents a simplified methodology for assessing design parameters of a constellation of the 5G Internet of Things information satellites positioned in an extremely low orbit at the altitude of 200 km and integrated into the non-terrestrial information network. Such network includes not only the space, but also the airborne segments. The paper demonstrates exponential dependence of the total number of satellites on the permissible elevation angle above the horizon. It presents results of computing the operation altitude for the atmospheric airborne vehicles included in the non-terrestrial network and shows advantages of introducing the network atmospheric segment. They include: reducing power consumption on board a spacecraft by 1.2 times; increase in the radio communication session duration by 1.9 times; reducing the satellite constellation size by 3.3 times; as well as reduction in the constellation total mass by 3.4 times compared to the Non-Terrestrial Network (TTN), which is not using the airborne segment. Main design parameters of a satellite included in the constellation are provided.
