In Earth orbiting space missions, the orbit selection dictates the mission parameters like the
ground resolution, the area coverage, and the frequency of coverage parameters. To …

Orbit design is a very important and fundamental task in the mission analysis and design of
a satellite. In the present paper, a multiobjective optimization tool is developed for the …

The development of oceanography and meteorology has greatly benefited from satellite-
based data of Earth's atmosphere and ocean. Traditional Earth observation missions have …

The outbreak of miniaturized satellites is increasingly demanding well-performing attitude
determination and control systems (ADCS). Testing an ADCS directly using hardware is …

This paper introduces a new set of compatible orbits called “Two-Way Orbits,” whose ground
track path is a closed-loop trajectory that intersects at certain points with tangent …

The ionospheric environment has become a focal point in the study of earthquake-related
anomalies. In particular, both electromagnetic anomalies and particle bursts have been …

Access to space has consistently presented difficulties, particularly for universities and
research with limited financial resources. Overcoming high costs, long development times …

This paper introduces a new set of orbits, the “Repeated Shadow Track Orbits.” In these
orbits, the shadow of a spacecraft on the Earth visits the same locations periodically every …

The mission concept “16U4SBSP”, funded by the European Space Agency through the
Sysnova campaign “Innovative Missions Concepts enabled by Swarms of Cube-Sats”, aims …

In order for a satellite to achieve a sun-synchronous orbit (SSO), it must have a nodal
precession rate equal to the revolution rate of the Earth around the Sun. However, sun …
