sat-nms MANTN18/24 Electrical Motorized Antenna
SatService has a long and successful history of small motorized antennas. In the beginning the main activities where in Ku-band frequency range (RX 10.7 to 12.75GHz / TX 13.75 to 14.5GHz) and due to the customer demands later on the activities where extended. One example are the L- and S-band frequency bands.
The sat-nms MANTN18/24 antenna is a fully electrical motorized 1.8m Antenna or 2.4m Antenna. The antenna can be electrical positioned in elevation, azimuth and if necessary, also in the polarization axis. The system can be used as a simple positioner or with the assistance of a beacon receiver and a software upgrade from positioner to step-track functionality in the sat-nms ACU-ODM module to track inclined orbit satellites. The customer operator interface is via web-browser, HTTP protocol via TCP/IP or via serial interface with an ASCII protocol. Certainly, the sat-nms MANTN18/24 antenna can also be fully integrated into the sat-nms MNC monitoring & control system. The sat-nms MANTN18/24 antennas are easy to install. For detailed information concerning installation instructions, please refer to the documentation section of this web site.
Applications
Typical application for which you can use these motorized antennas are:
- occasional use SNG central station receive only antenna pointed to different satellites
- monitoring antenna which can scan sequentially the orbital satellite arc
- universal backup antenna to recover failed fixed satellite links on differnet satellites due to its motorization
- universal up-link antenna to generate pilot signals, for example L-band pilot signals in INMARSAT satellite system
In order to cover our user requirements, the system is divided into three main modules:
- 1.8m or 2.4m Antenna including the necessary feed system
- 2 axis Mount for azimuth and elevation
- Electrical polarization adjustment if required
- ACU-ODM Antenna Control Unit for electrical motorization in all three axis
For step-track mode a beacon receiver can be directly connected to the sat-nms ACU-ODM:
- sat-nms LBRX L-Band Beacon Receiver
The compact design of sat-nms ACU Outdoor Module and sat-nms Beacon Receiver allows the integration of the complete Antenna Control Unit in a cabinet at the antenna.
