Portable satellite terminal test method and device

Abstract

The invention discloses a portable satellite terminal test method and a device and belongs to the technical field of satellite communication. The portable satellite terminal test method and the device comprise a first satellite communication machine, a second satellite communication machine, a noise generation unit, a power divider, a signal combiner and a power source module used for supplying power. The noise generation unit comprises a noise source generator and a noise amplifier, wherein the noise source generator simulates a noise signal under an actual use environment of a satellite and inputs the generated noise signal into the signal combiner through the noise source amplifier and the power divider in sequence. The first satellite communication machine sends out a carrier signal to the signal combiner. The signal combiner mixes the carrier signal with the noise signal, a testable noise load signal which fits in with the satellite communication machines is generated, and then the noise load signal is sent to the second satellite communication machine to be tested. According to the portable satellite terminal test method and the device, the signal strength sent out by a system and a terminal is enabled to meet signal input requirements of a satellite device, and a test can be achieved with no need of getting on the satellite.

Description

technical field [0001] The invention relates to a testing method and device for a portable satellite terminal, belonging to the technical field of satellite communication. Background technique [0002] Satellite communication is a kind of communication method in emergency communication, which is widely used in emergency rescue and disaster relief work such as meteorological emergency, fire emergency, government emergency, and earthquake emergency. But for different industries, there are various satellite communication systems and satellite terminals, so the test of each system and the test and effect of satellite terminals are particularly important. The test of satellite devices needs to occupy a large amount of satellite bandwidth resources. At the same time, satellite bandwidth resources are limited, and satellite bandwidth resources may not be enough at any time, and there are satellite bandwidth resources that are unintentionally or intentionally interfered by other use...
