Thisgeoidalheightwillagreewithlocalheightdatumsmoreaccurately.Itispossibletouploada
subgriddedgeoidmodelfileratheraglobalgeoidmodelfile.Aglobalgeoidmodelfileistoolarge
toloadintoreceivers,soyouneedtoreduceitssizeto
lessthan1Kb.
1. UsetheTrimbleBusinessCentersoftware‐HeavyConstructionEditiontosubgridthefile.It
producesa*.ggffile,whichyoumustrenametoa*.sgdfile.
2. ImportitintoanapplicationfileintheConfigurationToolBoxutility.
3. UsetheConfigurationToolBoxutilityto
selectthecoordinatesystemtouploadthe*.sgdfile.
4. UsetheConfigurationToolBoxutilitytoloadthatfiledirectly,ifyourcomputerisconnectedto
thereceiver.Otherwise,importtheapplicationfileusingthewebinterface(selectReceiver

 Inmanycasestheinclinedplanemethodisusedasitisofteneasiertogetthisfromasite
calibration.Iffourormorecontrolpointsarewelldistributedaroundthesite,thentheSCS900
sitecalibrationprocessgivestheoptiontofitaninclinedplanetomap
theGPSellipsoidal

Onceitisloadedintothereceiver,thereceivercanthenoutputtheelevationvalues.Forexample,
