This paper opens a series of articles expounding the fundamentals of the route theory for
satellite constellation design for Earth discontinuous coverage. In Part 1 of the series the …

Coverage analysis is an essential process when designing a satellite constellation, and the
variations of global revisit characteristics are usually elusive in discontinuous coverage …

This paper presents an analytical model for calculating the Earth discontinuous coverage of
satellite constellation with repeating ground tracks by integrating and extending the …

For the visibility optimization problem of satellite constellations, this paper presents an
efficient hybrid optimization method taking multiple constraints into account. To reduce the …

This paper proposes a geometrical multi-satellite discontinuous-coverage analysis method
for arbitrary fields that considers the J 2 perturbation. First, to calculate the single-satellite …

The present work proposes a closed-form solution for circular repeat ground track (RGT)
orbit designs and constellations and its application strategy. The proposed solution is an …

The ninth edition of the China Trajectory Optimization Competition (CTOC9) considered the
problem of navigation augmentation over a set of Chinese cities, wherein the competitors …

This paper mainly deals with the configuration design of hybrid constellations for Earth
discontinuous coverage. Firstly, a general design model of the hybrid constellation with …

Satellite coverage analysis is a fundamental performance assessment element in remote
sensing and communications' services projects. Coverage is a key parameter in the …

Designing repeat ground track (RGT) synthetic aperture radar (SAR) constellations for
achieving rapid revisits over key areas is essential to employ spaceborne differential …
