The 7.3m integrated terminal for remote sensing, TT&C and data transmission, independently developed by Hebei Mota Electronic Technology Co., Ltd., has completed system commissioning. The antenna operates smoothly with excellent dual-motor anti-backlash performance.

The system adopts a composite tracking mode: the S-band supports high-precision program track, while the X-band is equipped with monopulse auto-tracking capability. The coordination of the two modes guarantees stable full-sphere tracking from low elevation to high elevation angles.

The antenna servo drive system is deeply optimized. Its PID control loop features rapid response and ideal convergence, establishing a solid and reliable foundation for antenna motion control.The system demonstrates outstanding high-dynamic response performance.

Superior dynamic performance delivers ultra-high tracking accuracy. During tracking at a high elevation angle of up to 75°, the antenna’s X-band monopulse auto-tracking system maintains stable target lock throughout the operation. The real-time angular error voltage shown on the display is stably constrained within an extremely narrow range of ±0.1V, indicating that our monopulse tracking capability has reached advanced industry standards.
