Laser Inter-Satellite Link Visibility and Topology Optimization for Mega Constellation

In this paper, we begin by describing the Starlink constellation’s configuration plan, treating each satellite as a network node, naming and numbering various nodes, then classifying laser interstellar links (LISLs) according to their orbital alignment whether they are permanently visible. Whereupon, method for calculating respective theoretical distances required establishing LISLs under two distinct scenarios, co-orbital hetero-orbital analyzed, optimal phasing factors proposed solving an optimization algorithm shortest distance. The OneWeb constellations, well constellation states of simulated, respectively. with F = 11 obtains best coverage between 60° north south latitudes predicated upon analysis N Asset Coverage. Following that, first phase deployment was modeled in order analyze count number permanent orbit, adjacent to, nearby. Subsequently, characteristics azimuthal, elevation, range (AER) were subsequently analyzed ascertain variation law compile temporary that could be established at inter-distance ranges. Finally, on simulation results, connection strategy is evaluated static topology constructed.
