Configuring the receiverThis section covers receiver configuration for:• GPS limits• Corrections• FiltersNote — At mid latitudes, the GPS cross-track errors that occur when you drive East–West are typically double the cross-track errors that occur when you drive North–South. This is a characteristic of all GPS receivers and guidance systems, and occursbecause the GPS satellite orbits do not go over the poles. For GPS system statusdetails, go to http://www.navcen.uscg.gov/ado/GpsActiveNanu.asp.GPS limitsYou can configure the minimum acceptable number of satellites and the HorizontalDilution of Precision (HDOP) that must be present before GPS guidance will start.HDOP is a measure of accuracy based on the geometry of the satellites in the sky. AnHDOP value of 2.0 or less is considered good.Note — The GPS Limits settings can only be altered when you use a TSIP-capableGPS receiver. If the Input field is set to Autopilot, they are unavailable.To allow guidance to start in an area that has many trees,hills, or other obstacles, reduce Min Satellites to 5, orincrease Max HDOP to 3.0. This allows guidance to startwith lower accuracy positions. To configure thesesettings, select GPS / GPS Limits.CCAUTION — Changing any of the GPS Limits default settings can cause GPS position errorsgreater than one foot. If you are using the EZ-Steer system, these errors can cause theEZ-Steer system to steer the vehicle offline.Note — If you are using the EZ-Steer system, the EZ-Steer system will disengagewhen these limits are exceeded.If the lightbar has an integrated GPS receiver, or if youuse the lightbar with a high accuracy smart antenna, youcan also specify a minimum elevation and a minimumSNR for GPS satellites. (Satellites that do not meet thecriteria will not be used). However, if you lower thesevalues, this may result in more GPS position drift.44 Using GPS EZ-Guide Plus Lightbar Guidance System Getting Started Guide
CorrectionsTo improve GPS accuracy, the integrated GPS receiver uses correction messages froma Wide Area Augmentation System (WAAS) satellite, European GeostationaryNavigation Overlay System (EGNOS) satellite, or Multifunctional Transport SatellitebasedAugmentation System (MSAS) satellite.Note — MSAS is still at an early stage of development, and will be for use only inJapan.The following correction options are available:Receiver None WAAS/EGNOS Beacon Omni* VBS Omni* XP/HP RTKIntegratedIntegrated lightbarreceiverTSIP-capable– DGPS smartantennaFFFF– DGPS/OmniSTARsmart antennaF F F– DGPS box receiver F F F F– High accuracysmart antenna– High accuracy boxantennaF F F F FF F F F F FTo access the correction options, select GPS / Corrections.BTip — The selected TSIP-capable GPS receiver determines which corrections areavailable in the Corr field. You cannot configure Corrections for non-TSIP-capableGPS receivers.EZ-Guide Plus Lightbar Guidance System Getting Started Guide Using GPS 45
