Chapter 3 OEM7 Receiver OperationOEM7 Installation and Operation User Manual v1 53Figure 21: STEADYLINE UAL - Out of Bounds ExampleA The position type is OPERATIONAL.Higher accuracy corrections are lost. The receiver changes to a lower accuracy solution.STEADYLINE operates in Maintain mode while solution accuracy remains within the Operationallimit.B The solution accuracy exceeds the operational limit. The position type changes to WARNING.The STEADYLINE mode changes from Maintain to Prefer Accuracy.C The solution accuracy exceeds the warning limit. The position type changes to OUT_OF_BOUNDS.STEADYLINE is disabled.3.8 Enabling SBAS PositioningOEM7 family receivers are capable of SBAS positioning. This positioning mode is enabled usingthe SBASCONTROL command:sbascontrol enable autoWhen the command is entered, the OEM7 family card automatically tracks the SBAS that is oper-ating in the region (e.g., WAAS or EGNOS) and applies the corrections from the service. On asimulator, leave the test mode parameter off or specify NONE explicitly. For more on SBAS,refer to application note APN-051 Positioning Modes of Operation (additional Application Notesavailable at www.novatel.com/support/).3.9 Enabling NovAtel CORRECT with PPPL-Band equipped receivers can achieve sub-metre position accuracy using correction datareceived from geostationary satellites. To use the L-Band corrections, an L-Band-capablereceiver model and antenna are required (refer to our web site www.nova-tel.com/products/gnss-antennas for information on NovAtel L-Band-capable antennas).For more information on L-Band positioning, refer to:l NovAtel Application Notes: APN-061 NovAtel CORRECT with TerraStar or APN-062 NovAtelCORRECT with Veripos (service dependent) available from www.nova-tel.com/support/search/items/Application%20Notel the OEM7 Commands and Logs Reference Manual (OM-20000169) for log/command detailsand/or
