The effects of orbital parameters accuracy on Doppler frequency shift for intersatellite optical communication

Investigation of Doppler Frequency Shift Effect on the Performance of Four-Channel Space Chaotic Laser Communication

“…From (23), BER is related to SNR directly. To explain the relationship between frequency shift and BER, we further calculate the average SNR.…”

“…For four-channel space chaotic laser communication system. One terminal is on the satellites in geosynchronous orbit, which is a satellite communication transfer station [23]. Other terminals are on the satellites in low Earth orbit or mid-Earth orbit.…”

“…Since the existence of the pointing error, BER is related to the radial displacement r between the center of the beam and the center of the detector, as shown in (23). In light of the pointing error varying much more slowly than the transmitted digital signals, the ensemble average BER can be expressed as the integral of BER(r) and the probability density function (PDF) of radius deviation ρ(r) based on [22].…”

Simplified solution for osculating Keplerian parameter corrections of GEO satellites for intersatellite optical link

“…To use the on-board propagators sufficiently, some periodic corrections are needed based on the ground station ranging and antenna angular information (Yılmaz et al, 2012). Furthermore, these inaccurate orbital data lead to minor errors in the Doppler frequency in optical communication (Yılmaz and Cavdar, 2013).…”
