However, SatQKD systems face significant challenges due to satellite orbital movement, atmospheric losses, fading channel and excess noise. Given these challenges, in this work, we investigate the feasibility of the discrete-modulated continuous-variable QKD (DM-CVQKD) protocol using weak coherent pulses and homodyne detection against collective Gaussian attacks for the low Earth orbit SatQKD applications. We evaluate the atmospheric loss model with respect to the satellite overpass geometry and channel fading effects to determine realistic channel parameters such as transmissivity and excess noise. With these channel parameters, we present the asymptotic secret key rate (ASKR) and finite-size secret key rate (FSKR) analysis and identify operational boundaries across different turbulence regimes in terms of satellite elevation angle, the channel transmissivity and excess noise due to various losses along with the suitable time of execution of the protocol.
