Abstract: Thedeformationoflargeflexiblemeshantennaundergravityloadisremarkableandmixedwiththemanufacturingerror,whichbringtremendoustroublestothesurfaceaccuracyadjustingwork.Tosolvetheproblem,firstly,thearticleexpatiatedallkindsofsurfaceerrorsexistinginthereflectormanufacturingandworking;secondly,thearticleprovidedandcertifiedthecorrelationsamongtheerrorsespeciallymanufacturingerrorandsurfaceerrorswhenthereflectorisputCupupandCupdown.Byapplyingthosecorrelations,theeffectonthereflectorsurfaceerrorboughtbygravitycouldbedecreased,whichprovidedgreatadvantageforsurfaceaccuracyadjustingonground.Tomeettheengineeringrequirement,aflowchartofhowthesurfaceaccuracywouldbeadjustedwasproduced.Itcanreducethereversalfrequencyofreflectorandsavetimeduringsurfaceaccuracyadjusting.
