There are thousands of active satellite constellations in space nowadays. Their types and parameters differ depending on the area of applications.
Design and Optimization of Circular Satellite Orbits for Full Earth Coverage One of the several tasks that a satellite engineer performs when designing a network of satellites is determining the orbit of each satellite in the network. In this paper we are presenting a MatLAB based application that...

In a previous study, the theory of Gabbard diagram formation for fragments of a satellite breakup in circular orbit was presented including the 'X' formation, the equations of the apogee and perigee lines, the forbidden zone, the smear o... RC Reynolds,A Tan,M Schamschula - 《Advances in...
Trailing formation: Satellites share the same orbit and therefore follow one another on the same path. The satellites are configured to maintain a predetermined relative angular separation in their orbit. It is worth noting that the relative angular spacing in circular orbits remains constant throughou...

Fig. 1.5. Scientific CubeSats: 107 launched from 2003 to 2018; 46 in 2017 alone. 7 of the 107 were lost due to launch failures (labeled FTO in the plot; FTO = Failed to Orbit). Two mission status categories not plotted are those that were Dead on Arrival (21), and those whose...
A geostationary satellite carries with it a solid-fuel rocket engine to provide the necessary “kick” at the apogee of the satellite's transfer orbit to place it in a circular equatorial orbit with essentially zero inclination. The apogee engine and its propellant weigh about as much as the ...
