(about 100 and 1,000 miles) above Earth. Satellites do not orbit below 160 km because they are affected byatmosphericdrag. (The lowest orbiting satellite, the Japanese satellite Tsubame, orbited at analtitudeof 167.4 km [104 miles].) Satellites in LEO have orbital periods between 90 minutes...
LEO satellite communications systems.In this paper was analysed the possibility of communication sessions with the small spacecraft via the Globalstar system. The duration of communication sessions was estimated. It was made a stochastic analysis of the data transmission capabilities between the two ...

Δ𝑇𝑚ΔTm is the time interval from the knot point before 𝑡𝑖ti to the epoch 𝑡𝑖ti. The estimable parameters are clocks at a series of knot points separated by Δ𝑇ΔT. The determined factor of the PWL model is the time interval Δ𝑇ΔT. Using the same satellite ...
Suppose that there are I HAP drones at an altitude of ℎ1h1 and J LEO satellites at an altitude of ℎ2h2 in the space–air–ground integrated network. The LEO satellite set is denoted as 𝒥={1,2,⋯,𝐽}J=1,2,⋯,J, and the HAP drone set is denoted as ℐ={1,2,⋯...
Table 3 illustrates a significant finding indicating the emergence of non-convergent epochs when the satellite orbit altitude dropped below 1000 km. With a continued decrease in orbit altitude and an escalation in initial value errors, the occurrence of convergent epochs diminished. This observed trend...
Compared with the medium Earth orbit (MEO) and geostationary (GEO) satellites of different global navigation satellite systems (GNSSs), LEO satellites exhibit their advantages in their large number, low altitude, fast speed and strong signal strength [1]. The increased number of satellites improves...
