Product Description

4.5m S band telemetry satellite antenna

For the telemetry antenna,it is customized antenna,we will quote and produce the antenna basing customer's detailed requirements.Any query or demands for it,please feel free to contact me.

The Characteristics of the telemetry antennas are as followed:

1)Track low-orbit satellites with orbital altitudes within 400~1000km;
2) Receiving and transmitting function for S band;
3) Communication capability for s band;
4) Over the top tracking capability;
5) Receive control commands and target capture tracking parameters of station control system in real time. Capture and track the satellite by the servo control system;
6) Under no visually obstacle conditions, antenna track and capture satellite when elevation angle is 5º, antenna stable track and receive when  elevation angle is  7º;
7) Fully automate tracking satellite;
8) Collect fault information and status parameter,and automatically report to the station control subsystem and displays it by itself;
9) Automatic monitoring function with tracking link device;
10) Record log function, and are automatically report key parameters to the station control subsystem on a regular basis;
11) Operation and security function, safety brake, soft limit, electrical limit, buffer protection, work alarm etc.
12) Own lightning protection, surge protection and overcurrent protection functions;
13) Calibration capability when antenna angle is zero, to complete the satellite fast capturing.
