In order to meet the urgent needs of ubiquitous communication and intelligent connection of eve-rything,the ground 5G cellular communication system and non-terrestrial network system realize comple-mentary advantages,integrated development and resource sharing.Non-terrestrial network is a completely new form of communication system.In this paper,it will first discuss 5G non-terrestrial network system ele-ments and related application scenarios.After this,the analysis of the error vector magnitude will be dis-cussed according to the 5G base station test methods and radiated conformance testing.Finally,by compa-ring the test waveforms from self-designed program and commercial software,it shows how the signal-to-noise ratio,channel bandwidth and subcarrier spacing would impact error magnitude test.This paper pro-vides the product design of non-terrestrial network equipment for the latest standards of 3 GPP testing meth-ods and save money for the volume production of related equipment.
