General Description 

The STARWIN1.8m vehicle-mounted antenna is a fly-away antenna equipped on large command vehicle,

the whole system is designed by China Starwin Science&Technology Co., Ltd. especially for the emergency

command communication market. The system is quit suitable for the large emergency missions with the function

of large capacity of information and high quality communication. The main features of the system include high

strength structure, perfect transmission accuracy,1.8m antenna and operating in whole day.

The system have three main functions: transmission with large capacity of information,operating in whole day with

strength structure,automatic control for a long time without disconnection.

The functions and features of the system

Ø Easy operating: No need for professional operators, the system can be pointed at the satellite within 3mins by

    using the one-key pointing function.

Ø The system can be operated in whole day with large torque and high accuracy transmission. The structure of the

     system is designed with high strength by using the military motor and reductor imported from Germany.

Ø Three operating mode: auto,electric,manual. 

Ø Military quality:Using the environment resistant materials which meet the MIL-STD-810F requestment. The

    system pass the environment test for the harsh communication conditions.

Ø Perfect performance:high feed RF efficiency, high gain, low sidelobe, excellent cross polarization.

Ø Highly integrated:the system was put into a 2U standard box in which including a three axis positioner,a GPS

    receiver and a electronic compass, the system has the function of auto pointing satellite.

Ø Have monitor port.

The system composition of the STARWIN1.8m Vehicle mounted antenna 

STARWIN1.8m vehicle mounted antenna system is mainly consist of the 1.8m feed system,the three axis drive

system,the automatic control system,the power drive system,the satellite attitude acquisition system,the beacon

receiver system, etc. The whole system is divided in to two parts, one is inside vehicle control system, another is

outside vehicle antenna. The interconnection between two parts is simple and stable, which is shown below:
