Outputtingelevationsbasedonageoid
ThereceivercomputesellipsoidalheightsthatareconvertedbytheSCS900software
intolocal
elevationsusingtheinclinedplanemethodorageoid.
Ifyourequirethereceivertooutputelevationsforanotherapplicationintermsofthegeoid
(orthometricheights),thenthedefaultgeoidmodelinthereceiverisnotaccurateenoughfor
precisepositioning.
Toloadanduseaprecisegeoid
model:
 Thereceiverneed4.12firmwareorlater.
 Thefilesizeoftheusergeoidfileneedstobe1Kborsmaller.Thefilemusthaveasuffixof
.sgd.

programs:
TrimbleSiteVisionOfficetotrimthegeoidfiledownto thissize.
TrimbleGridFactorytostorethesubgriddedgeoidfilewiththe.sgdfileextensionratherthan

TrimbleGeomaticOfficeandTrimbleBusinessCenter‐HeavyConstructionEditionsoftwarealso
enablesthecreationofsub‐gridsofgeoidmodels.Inthiscase,itisnecessarytosetupaprojectthat
referencesthefullgeoidmodelsothatsub‐gridsofitcanbeexported.
