When your satellite ground station demands zero-tolerance tracking accuracy, the Closed‑Loop Antenna Control System from Hebei Mota Electronics delivers enterprise-grade performance you can rely on. Our system integrates a three-level full closed-loop architecture encompassing position, speed, and current control layers. With a steady-state pointing error below 0.003° and system response time under 3 ms, you achieve millisecond-level deviation correction that completely eliminates cumulative error and drift.
Designed for high-dynamic LEO satellite tracking and deep-space applications, this product maintains annual pointing drift less than 0.01°, significantly reducing your calibration frequency. Whether you operate Ka-band ground stations, deep-space TT&C networks, or border defense radar systems, our military-grade solution ensures uninterrupted signal acquisition even under extreme environmental stress.
Your tracking challenges require instant response. Our three-level full closed-loop design utilizes high-precision encoders (23-26 bit resolution) combined with attitude feedback units to detect and correct deviations within 3 milliseconds. This eliminates the drift problems inherent in open-loop systems.
Traditional program-track systems follow predicted orbital paths. In contrast, our product continuously compares actual antenna position against target coordinates using real-time encoder data. This feedback-driven approach compensates for unpredicted variables like structural thermal warping and mechanical backlash.
Strong wind gusts and platform vibrations threaten your tracking precision. Our system features control bandwidth ≥100 Hz, enabling ultra-fast suppression of external disturbances. The high-speed feedback loop detects physical displacement instantly and applies counter-torque to servo motors.
Operating across temperature extremes from -45°C to +70°C, the system maintains consistent performance in harsh environments. This military-grade reliability makes it ideal for remote ground stations, maritime SATCOM platforms, and aerospace facilities where environmental stress is constant.
Your operations demand connectivity. Our full-system digital design seamlessly connects to upper computers and TT&C centers, enabling data synchronization and remote monitoring. You gain centralized control over multiple antenna systems with real-time performance analytics.
The system supports large-aperture antennas from 1.2m to 18m, adapting to deep-space exploration, radar tracking, and high-frequency Ka-band applications. This scalability protects your infrastructure investment as mission requirements evolve.

Q: How does closed-loop control vary from program-track systems?
A: Program-track takes after anticipated disciple ways from orbital databases. Our closed-loop framework employments persistent real-time input from high-precision encoders to adjust for unpredicted factors like air refraction, auxiliary shifts, and mechanical wear. This gives prevalent precision for long-duration following missions.
Q: Can the framework keep up following amid tall wind conditions?
A: Yes. The 100 Hz control transfer speed identifies wind-induced uprooting inside 10 milliseconds and applies immediate counter-torque through servo engines. Field tests affirm kept up following exactness in wind speeds surpassing operational limits of comparable open-loop systems.
Q: What happens if encoder criticism is briefly lost?
A: The framework moves to memory track mode, utilizing final known speed vectors and inertial information to keep up inexact indicating. Once input flag is re-acquired, the control circle naturally resumes ordinary operation without manual intervention.
Q: How frequently does calibration require to be performed?
A: Much appreciated to the
