Real‐TimeKinematic(RTK)operationprovidescentimeter‐levelaccuracybyeliminatingerrorsthat
arepresentintheGNSSsystem.ForallRTK,LocationRTK,orDGPSoperations,yourequirebotha
roverreceiverandasourceof correctionsfromabasestationornetworkofbasestations.
Thistopicintroducesthe
conceptofroveroperation,providesinformationtohelpyouidentify
goodsetuplocations,describesbestpracticesforsettinguptheequipment,andoutlinesthe
precautionsthatyouneedtotaketoprotecttheequipment.
ThesecondpartoftheRTKGNSSsystemistheroverreceiver.Theroverreceiveris
movedbetween
thepointsthatrequiremeasurementorstakeout.Theroverreceiverisconnectedtoabasestation
ortoasourceofRTKcorrectionssuchasaVRSsystem.Theconnectionisprovidedby:
 anintegratedradio
 anintegratedcellularmodem
 acellularmodeminthecontroller

 anexternalcellularphonethatisconnectedtothereceivereitherbyBluetoothwireless
technologyorbymeansofacable
Inmostroverapplications,thereceiveroperatesentirelyfromitsownintegratedbatteryunit.
However,youcanuseanexternalpowersupplyifoneisprovided.Theinternal
batterythenactsas
anuninterruptiblepowersupply,coveringanyexternalpowerfailures.
Choosearoverreceiveraccordingtotheneedsofthejob:
 AGNSSSmartantennaincorporatestheGPSreceiver,GPSantenna,powersupply,andreceive
radiointoasinglecompactunit.ASmartGPSantennacanbe
rapidlysetuponapole,vehicle,
orbackpack.Thismakesiteasytocarrywhenyouaremeasuringaroundthejobsite.
Forgoodroveroperation,observethefollowingsetupguidelines:
 PlacetheGNSSantennainalocationthathasaclearlineofsighttotheskyin
alldirections.
Donotplacetheantennanearverticalobstructionssuchasbuildings,deepcuttings,site
vehicles,towers,ortreecanopy.GNSSroversandthebasestationreceivethesamesatellite
signalsfromthesamesatellites.Thesy stemneedsfivecommonsatellitestoprovideRTK
positioning.
 WARNING–TheGNSS
antennaanditscablingshouldbeinstalledinaccordancewithall
nationalandlocalelectricalcodes,regulations,andpractices.
Theantennaandcablingshouldbeinstalledwheretheywillnotbecomeenergizedasaresult
offallingnearbypowerlines,norbemountedwheretheyaresubjectedtoover‐voltage
transients,particularlylightning.Suchinstallationsrequireadditionalprotectivemeansthat
aredetailedinnationalandlocalelectricalcodes.
