However, the traditional pulse train signal has a poor performance in measuring remote and high speed targets because of range or velocity ambiguity, and the antijamming
performance is also low.
Hybrid controller performance will be verified by three experiments: fixed point hovering, expected tracking, and antijamming
As shown in Figures 1 and 2, the BOC signal has two characteristics splitting spectrum peaks and multiple autocorrelation peaks, which enhance the antijamming
ability and improve the precision of the acquisition [14, 15].
We analytically derived closed-form expressions of the system BERs under the BBJ and the PTJ environments, from which we revealed that in general increasing P can enhance the system antijamming
Reference  proposed an output-feedback Hm preview controller and improved the antijamming
performance and robustness of UAV flight control system.
To achieve this goal, hybrid approach to combine TDMA with novel time synchronization approach and Frequency Hopping Spread Spectrum (FHSS) was presented to include antijamming
and collision prevention.
 propose an antijamming
scheme to minimize the effects of jamming attacks from malicious SUs, which constantly transmit packets to keep the channels busy at all times so that SUs are deprived of any opportunities to transmit.
Liu and Li  also propose an adaptive spectrum sharing scheme based on frequency hopping communications for antijamming
in heterogeneous networks.
Therefore the antijamming
property is an important issue for MEMS-based UTC GPS/INS system.
It also increases the antijamming
capability of the system as well as the efficiency.
This control method avoids the conventional dynamic surface control systems, relies on accurate mathematical models and improved antijamming
Its control system dynamic and static quality and robustness in the case of time-varying parameters and antijamming
capability are superior to the conventional PID control method.
