  • 摘要：In classical separation of the systematic errors of guidance instruments of moving base spacecraft, launch origin error not only affects the apparent velocity in platform's inertial frame, but also affects the tracking data in the launch coordinate system. If the tracking data of the launch coordinate system is still used in error separation, it shall not be possible to deduct the influence of launch origin error on tracking data. This paper proposes error separation in DX2 geocentric coordinate system to solve this problem. As tracking data in geocentric coordinate system is transformed from topocentric coordinate system, the tracking data in geocentric coordinate system is not influenced by launch origin error. Evolutionary strategy algorithm is used in error separation to avoid the high complexity of the function of geocentric coordinate system. Simulation results show that the systematic errors of guidance instruments and the launch origin error can be separated simultaneously using this method. Moreover, no obvious deterioration of the separation results is found with the increase of launch origin error.%在经典动基座飞行器制导工具系统误差分离中,原点误差不仅影响平台惯性系下的视速度,而且对外测发射系数据也有影响.若仍利用发射系数据进行误差分离,将无法扣除原点误差对外测数据的影响.因此,提出在DX2地心系下进行误差分离,由于地心系下的飞行数据是由测站系转换而来,故地心系下的外测数据不受原点误差的影响.鉴于地心系下误差方程的复杂性,文中利用进化策略方法分离误差,可简化公式推导.仿真计算结果表明:该方法能同时分离制导工具系统误差和原点误差,且分离结果不随原点误差的增大而明显变差.

Accurate values can be computed with engineering parameters using the approximation equations derived from the change of SNR of the high alphabet tones before and after application of the method.

  • 摘要：DS/FH(直接序列扩频/跳频扩频)混合扩频信号的快速捕获问题亟待研究.电离层色散效应增加了BPSK(二相相移键控)调制的DS/FH信号捕获的复杂度,并导致不同频点信号载波相位难以保持连续.通过估计电波传播路径上TEC(电子浓度),可以消除电离层色散效应的影响,利于应答机精确测速.提出一种划分子带的信号捕获方法,放宽TEC搜索步进,缩短搜索TEC的时间,从而实现信号的快速捕获.分析了划分子带个数与捕获时间及捕获能量损失的关系,在实现过程中可通过调整子带的个数来控制捕获能量损失,使得捕获模块设计更加灵活.%The urgency of research on fast acquisition of DS/FH (Direct Sequence/Frequency Hopping) spread spectrum signals is described. With the existence of ionospheric dispersion, the carrier phase continuity of a phase-coherent FH system is disrupted and the complexity of acquisition is drastically increased. Through search of TEC (Total Electron Count) along the path, the receiver is able to compensate for phase discontinuity and to perform coherent acquisition. A new acquisition strategy named Band Division Accumulation is proposed. It is proved that the strategy can broaden TEC search period and thus reduce search complexity. The relationship between the number of sub-bands and energy loss in acquisition is analyzed. The accumulation loss of acquisition can be adjusted by altering the number of sub-bands and this is beneficial to receiver adaptability.
  • 摘要：为确保载人航天上升段测控实时外弹道跟踪的精度和可靠性,针对目前测控资源冗余、测量信息利用率低的缺点,结合航天测控的特点提出基于联邦UKF(无迹卡尔曼滤波)的测控数据融合处理方法,并对需要解决的关键技术问题进行了分析.仿真结果表明:采用基于联邦UKF的数据融合方法,外弹道实时跟踪精度提高约30％,解决了弹道优选方法存在阶跳的问题,算法的收敛速度可以满足实时导引的要求.%Following analysis of the redundancy of current TT&C (Tracking, Telemetry and Command) resources and low utilization efficiency of measurement data, and the features of space TT&C, a TT&C data fusion method based on federated UKF (Unscented Kalman Filter) filter is proposed to ensure the reliability and accuracy of tracking in the boost phase of manned spaceflights. Key technologies for multi-source measurement data fusion are analyzed. Computer simulation shows that the tracking accuracy is increased by thirty percent by using the federated UKF data fusion method. Moreover, the fused ballistic curve is continuous and the convergence speed meets the real-time requirements of guidance for other measurement equipment.
