Solar Scintillation Effects on Telecommunication Links at Ka-Band and X-Band

摘要: Many deep-space missions encounter solar conjunction. Some missions, such as Solar Probe and Stardust, conjunction during their main missions. The Sun–Earth–Probe (SEP) angle is used to describe the degree of When SEP small, plasma causes degradation in telecommunication link performance. In this article, we present a model that developed study amplitude scintillation effects on telemetry signals at both 8.4 GHz (X-band) 32 (Ka-band). Both analytical simulated results show that, low bit-error rate (<10−5), X-band links suffer 8.2 dB for mission perihelion. Ka-band links, however, only few tenths dB. addition 8-dB advantage over under conditions, there also 4to 6-dB due higher frequency.
