When Enforce Location Accuracy is enabled set the Accuracy threshold used to capture GPS coordinates.
Geoid  varies

Use the drop-down list or the pencil to select the Geoid you want to use. (See the Choosing Geiods section below.) The pencil allows you see and delete the installed Geoids and search for and download your desired Geoid model. Once downloaded, the Geoid model will appear in the drop-down list.

  • No Geoids are installed by default
  • Online Geoids are filtered by current location by default
Coordinate Reference System
Displayed Coordinate System* World Geodetic System 1984 (WGS84) Latitude/Longitude (4326)

Spatial reference identifier based on European Petroleum Survey Group (EPSG) codes. Options are

  • WGS84 Latitude/Longitude (4326)
  • WGS84 UTM
  • Other
Coordinate Display Format Decimal degrees (DD.DDD) When the displayed coordinate system includes a variety of display options, this field will appear. If there are no options available in the chosen coordinate system, this field will  not display.
Coordinate Reference System ID  

Use this field to select the SRID for the spatial reference system Uinta uses to display coordinates. This option appears when you select other as the displayed coordinate system. Use the drop-down or the plus. To find the coordinate system you want to use,

  • Search by SRID or name
  • Filter the search results by any combination of system types 
    • Geographic
    • Projectected
    • Geometric
Geode Receiver Settings
Update Rate 1hz Sets the message output rate through the active connection port
Correction Source Auto Sets the correction sources to use. The Auto setting gives less precise, but more reliable corrections. 
SBAS Auto

Sets the SBAS satellite signal to use for an SBAS-corrected solution. Options are

  • Auto
  • EGNOS
  • GAGAN
  • MSAS
  • SDCM
  • SouthPAN
  • WAAS
  • None
NTRIP
NTRIP Profile  

Select, add, or edit the NTRIP Profile you use. Use the drop-down arrow to select previously created profiles. Use the plus sign to create a new profile. Use the pencil to edit the profile. When creating a new profile, enter,

  • A name for the profile
  • The address of your NTRIP caster
  • The port being used
  • Your username
  • Your password
  • Use the checkbox to send (or not) the GGA to your caster.
  • Choose to apply a spatial reference correction source when active (in the Coordinate Reference System ID box). Use the drop-down to choose or the plus sign to add. 
  • Choose, add, or download your mount point.
    • Use the drop-down to choose an existing mount point.
    • Use the plus sign to manually add the location of your mount point.
    • Use the download icon to download your mount point location.  

For specific instructions on using NTRIP with Geode, please see Use NTRIP with Geode in our knowledge base. 
NTRIP Connection   Use the Start NTRIP button to begin an NTRIP connection.
NTRIP Diagnostic Log   Information about the NTRIP connection.

*The display projection is WGS84 Pseudo-Mercator/Web Mercator (EPSG 3857) which creates a smooth rendering of maps and map tiles. For display purposes, when fully zoomed out the map projection repeats to create a continuous scrolling map. 

Choosing Geoids

Before you can select a specific Geoid, you will need to install it. Once the Geoid is installed, it will show in the drop-down list.

To install a Geoid,

  1. Tap the pencil.
    • A new box will display showing the Geoids you have installed, if any, and the Geoids available online.  
      • Mark the Filter by current location box to see only those Geoids for the area near your current location.
      • If you know a specific Geoid that you want to install, you can search by entering an identifying number. The picture below shows a search for Geoids including the number 18. 
    • Use the import from device button to select a Geoid you have saved on your device. 
  2. Once you see the Geoid you want select it.
