This paper studies acquisition and tracking of carriers by the Tracking, Telemetry and Command (TT&C) systems in low Signal-to-Noise Ratio (SNR) and high dynamic conditions for deep space applications. An associated carrier acquisition and tracking algorithm is proposed and it features FFT frequency-domain shift and accumulation algorithm in combination with variable bandwidth FLL-PLL algorithm with Doppler rate pre-compensation. The algorithm not only captures signal with high dynamics and low SNR but also achieves high tracking accuracy. Simulation results show that the proposed associated frequency estimation algorithm is capable of carrier frequency estimation with an error less than 0.5 Hz and it tolerates high Doppler dynamics under Eb/n0 as low as 3 dB.
