Description

Portable satellite communication device

Background

Satellite communication has the advantages of wide coverage, convenient and rapid networking, convenient realization of global seamless link and the like, and is considered as an important means essential for establishing global personal communication. When major natural disasters and other events occur, the ground public network communication is often interrupted, and a satellite communication mode is adopted to establish a communication link with a command center on an emergency site, so that the method becomes an optional technical means. The portable satellite communication system is suitable for being carried by a single soldier, can carry out rapid network deployment and service opening in areas where large-scale equipment such as vehicles cannot reach, and plays a constructive role in the emergency rescue process.

When the satellite is used for a portable communication system, the pitch angle and the azimuth angle required by aligning the satellite need to be calculated according to the satellite rail position information and the geographical position information of the location of the portable satellite communication system, and the satellite operation is automatically completed manually or through a servo motor.

The premise of the satellite portable communication system for the satellite is that the satellite portable communication system is horizontally arranged when the satellite is aimed.

The prior art means for solving the problems mainly comprise:

1. manually adjusting the horizontal mode: a gradienter is placed at the supporting leg of the satellite portable communication system to measure whether the satellite portable communication system is level or not; if not, the horizontal position is reached through a mechanical adjustment mode;

2. automatic correction level algorithm: the horizontal direction angle is measured by the built-in electronic level gauge, and the satellite alignment parameters are corrected to make up for the satellite alignment angle error caused by the fact that the ground is not horizontal.

However, most of the satellite portable communication systems are in emergency rescue or disaster relief scenes, and it is difficult to deploy the satellite portable communication systems on an absolutely horizontal plane.

Both of the above two methods for adjusting a satellite portable communication system by a level have certain drawbacks:

1. manual adjustment mode:

a) the external gradienter mostly adopts a method of observing the position of a water drop by human eyes to judge whether the water drop is in the horizontal direction, the observation of each person is possibly different, and certain deviation exists;

b) because the portable satellite communication system is usually not less than three supporting legs, the portable satellite communication system needs to be adjusted at least three times to confirm whether the portable satellite communication system is adjusted to the horizontal position, the method for manually adjusting the horizontal position has the disadvantages of more complicated operation steps, longer time consumption for horizontal adjustment and larger overall adjustment error;

c) an external level gauge is required to be attached to a person, and the device is not convenient to carry.

2. Automatic correction level algorithm: and judging whether the satellite portable communication system is in a horizontal state or not by using a built-in electronic level meter. Electronic levels typically employ either inductive or capacitive types. And converting the voltage reading into a voltage reading in an electromagnetic change or capacitance change mode to judge whether the voltage reading is in a horizontal state. However, the instrument may be affected by the application environment, so that certain errors exist in the horizontal measurement, and whether the parameters of the satellite are accurate or not and the effect on the satellite are directly affected.

Based on the above practical situation, a satellite portable communication device is provided.
