Dualfacemeasurements
Whenmeasuringthesametargetinbothfaces,thereflectorheightmaynotbechangedwhen
observinginthesecondface.Errorchecksaremadefordualfacemeasurementstoensurethe
samepointissightedwiththeotherface.
)
• Ifatargetpointismeasuredseveraltimesinthesameface,onlythelastvalidmeasure‐
mentisusedforcomputation.
• Forthecalculationofthestationposition,measuredtargetpointscanbere‐measured,
includedincalculations,orexcludedfromcalculations.
Measurementsnotincludedincomputations
Targetpointswith0.000heightarediscardedforheightprocessing.Ifatargetpointhasavalid
heightof0.000 m,use0.001 mtoincludeitforheightprocessing.
9.7.3 ComputationProcedure
Description
Themeasuringprocedureautomaticallydeterminesthemethodofevaluation,forexample
resectionorthreepointresection.
Ifmorethantheminimumrequiredmeasurementsareperformed,theprocedureusesaleast
squaresadjustmenttodeterminethe3Dpositionandaveragesorientationandheightmeasure‐
ments.
• TheoriginalaveragedfaceIandfaceIImeasurementsareusedforthecomputation
process.
• Allmeasurementsaretreatedwiththesameaccuracy,whetherthesearemeasuredin
singleordualface.
• EastingandNorthingaredeterminedbytheleastsquaresmethod,whichincludes
standarddeviationandimprovementsforhorizontaldirectionandhorizontaldistances.
• Thefinalheight(H)iscomputedfromaveragedheightdifferencesbasedontheoriginal
measurements.
• ThehorizontaldirectioniscomputedwiththeoriginalaveragedfaceIandfaceIImeas‐
urementsandthefinalcomputedplanposition.
