Enabling Sbas Positioning; Enabling Novatel Correct With Ppp; Figure 15: Steadyline Ual - Out Of Bounds Example - Novatel SMART7 Installation And Operation Manual

SMART7 Operation
C The solution accuracy moves back within the operational limit. The position type changes to
OPERATIONAL.
The STEADYLINE mode remains in Prefer Accuracy mode.
D The solution offset is removed.
The STEADYLINE mode changes from Prefer Accuracy to Maintain.

Figure 15: STEADYLINE UAL - Out of Bounds Example

A 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 Operational
limit.
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.

3.7 Enabling SBAS Positioning

OEM7 receivers are capable of SBAS positioning. This positioning mode is enabled using the
SBASCONTROL command:
sbascontrol enable auto
When the command is entered, the OEM7 receiver automatically tracks the SBAS that is oper-
ating in the region (e.g., WAAS or EGNOS) and applies the corrections from the service. On a
simulator, leave the test mode parameter off or specify NONE explicitly. For more on SBAS,
refer to application note
available at www.novatel.com/support/).

3.8 Enabling NovAtel CORRECT with PPP

L-Band equipped receivers can achieve sub-metre position accuracy using correction data
received from geostationary satellites. To use the L-Band corrections, an L-Band-capable
receiver model and antenna are required (refer to our web site
tel.com/products/gnss-antennas
For more information on L-Band positioning, refer to:
SMART7 Installation and Operation User Manual 0C
APN-051 Positioning Modes of Operation
for information on NovAtel L-Band-capable antennas).
