The most wide-spread orbits of small satellites are low circular near-Earth orbits (300–600 km) and middle elliptic orbits with a large eccentricity (the perigee is 250–600 km, the apogee — 4000–6000 km or up to 200000 km). The orbit inclination depends on the solved task. The pea...
After 24 minutes of flight, the satellite separated from the rocket, and entered the planned Earth-Moon transfer orbit with the perigee at 200 kilometers and the apogee at 420,000 kilometers. The satellite's solar panels and communications antennae were unfolded, according to the China National ...
Circular orbits are at the same altitude, while elliptical orbits contain the apogee (the highest point) and the perigee (the lowest one). Swarms with circular orbits revolve around our planet within 1.5 to several hours and typically fly nearly above the geographic poles. As for elliptical ...

1.oftenMoonThe natural satellite of Earth, visible by reflection of sunlight and having a slightly elliptical orbit, approximately 363,100 kilometers (225,600 miles) distant at perigee and 405,700 kilometers (252,100 miles) at apogee. Its mean diameter is 3,475 kilometers (2,159 miles), ...
In such an orbit, the satellite velocity with respect to the earth is constantly changing, reaching a maximum at perigee and a minimum at apogee. The footprint of the satellite on the earth is constantly changing as well, reaching a maximum diameter at apogee. Although these HEO systems can...
communication [Jastrow and Bryant, 1960; Shapiro and Jones, 1960; Muhlemen, Hudson, Holdridge, Carpenter, and Oslund, 1960].As reported earlier, the primary effect of solar radiation pressure on the Echo satellite is to change the eccentricity, and hence the altitudes of apogee and perigee. Th...
