In inclinations of retrograde, constellation has the same results as line with slope of +1. Due to the limit of 105 km altitude, “Reach” crosslinks of 6 satellites are shown in figure with red ellipse curve. This means that each satellite along the blue curve can connect continuously to...

(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...
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 ...
Using a satellite at an orbital altitude of 1100 km and an inclination of 55° as a case study, this analysis examines the distribution characteristics of average coverage for a single satellite with inclinations ranging from 40°~70° along different latitudes. The average number of visible sate...
The satellite communication channel adopts the tapped delay line (TDL) model. The signal strength in the multiple satellites scenario is based on the actual OneWeb constellation at an orbital altitude of 1200 km, with a user longitude of 112.99° and latitude of 28.22°. Table 2. System ...
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...
