In this thesis, we analyze several system parameters and performances for free-space optical satellite networks (FSOSNs), including phasing parameter, optical satellite link budget, tradeoff between network latency and satellite transmission power, and network latency minimization based on satellite transmission power constraints. We investigate the phasing parameter for Starlink Phase 1 Version 3 and Kuiper Shell 2 constellations. We find the best value of the phasing parameter. We investigate the link budget for laser inter-satellite link (LISL) and uplink/downlink and the effect of many constellation parameters on the satellite transmission power. We examine the tradeoff between network latency and satellite transmission power in FSOSNs from Starlink Phase 1 Version 3 and Kuiper Shell 2 constellations for different LISL ranges and inter-continental connections. We investigate the minimization of total network latency in the FSOSN resulting from Starlink Phase 1 Version 3 constellation for different LISL ranges and satellite transmission power constraints.
