“…In carrier phase measurements, it is necessary to output the carrier phase from the carrier tracking loop [29,30]. However, for the TDD mode in the ISL, the DOWR needs to convert two time measurements into equivalent instantaneous observations; that is, the influence of propagation delay on the measurement must be corrected [31]. Because each satellite needs to transmit signals from multiple frequency points over time, the tracking loop of the satellite segment for multiple frequency points will frequently lose lock and reconnect, resulting in unstable carrier phase tracking and ultimately leading to an incorrect calculation of the integer ambiguity.…”

With the development of navigation satellite constellation systems, to improve navigation service and orbit determination performance, the accuracy requirements for maintaining temporal references have increased rapidly. Among the current navigation satellites, a dual one-way ranging (DOWR) approach based on intersatellite links (ISLs) is widely adopted in the BeiDou system and global positioning system (GPS) to transmit satellite time reference information. However, the accuracy of DOWR is restricted by the pseudonoise (PN) code rate. To improve the accuracy of DOWR, the PN code measurement must be replaced by the carrier phase measurement. This paper introduces an algorithm that utilizes frequency hopping to achieve carrier phase ranging. In addition to the high-precision advantages of carrier phase measurements, the anti-interference performance of the ranging signal is also improved due to the characteristics of the frequency hopping signal itself. Ultimately, at a carrier-to-noise ratio of 40 dB-Hz, the measurement accuracy is 9.54 μm, while the PN code measurement accuracy in the same environment is 0.13 m. As the carrier-to-noise ratio increases, the measurement accuracy further improves.

“…The subband phase difference estimation technique is a core technology of the frequency domain synthesis method, whose performance directly affects the performance of residual delay and phase estimation [3]. Therefore, in future deep space communication-related missions, to improve the performance of antenna array signal synthesis under low SNR, the superior subband phase difference estimation technique is of utmost importance [4].…”

In future deep space communication missions, VLBI(Very Long Baseline Interferometry) based on antenna array technology remains a critical detection method, which urgently requires the improvement of synthesis performance for antenna array signals. Considering this, focusing on optimizing the traditional antenna grouping method applied in the phase estimation algorithm, this letter proposes a "𝐿/2 to 𝐿/2" antenna grouping method based on the maximum correlation signal-to-noise ratio(SNR). Following this idea, a phase difference estimation algorithm named "Couple" is presented. Theoretical analysis and simulation verification illustrate that: when 𝜌 < −10𝑑𝐵, the proposed "Couple" has the highest performance; increasing the number of antennas can significantly improve its synthetic loss performance and robustness. The research of this letter indicates a promising potential in supporting the rising deep space exploration and communication missions.
