The main features of the antenna are as follows:
1) excellent electrical performance of antenna:
A) gain: transmit >36.5dBi, receive >35.5dBi;
B) cross-polarization isolation: ≥30dB
C) side lobe: ≤ -12db
D) a standing wave 1.3 or less
2) plastic electroplated horn array antenna: it can be quickly mass-produced, with light weight and high gain.
3) independent of GPS information: using satellite beacons to track and correct gyro errors, it can still work normally without GPS information (just manually input the local longitude and latitude once before the initial satellite alignment).
4) initial star speed: GPS/BD module cold start positioning to star time <80s, hot start (or manual input) <60s.
5) high tracking accuracy: in the case of no occlusion, the tracking error is less than 0.5dB(RMS).
6) good stabilization effect: azimuth adopts closed-loop stabilization algorithm, fast steering or "S" travel can still accurately track the satellite.
7) fast recovery time of occlusion: occlusion time <5min, recovery time <3s; Occlusion time <20min, recovery time <5s.
8) quick satellite switching: the switching time between different satellites is <8s.
9) easy to use: it can realize the functions of dynamic star alignment and dynamic tangent.
10) easy maintenance: modular system design, simple interface specification, convenient fault diagnosis and maintenance.
11) safe and green operation: 24V dc operation, power consumption less than 150W, machine weight 78Kg.
12) easy integration: there are only 4 external interfaces, which are data output, dc power supply, if receiving and if transmitting, and the connection relationship is simple.
