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 24: 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
APN-051 Positioning Modes of Operation
(additional Application Notes
available at
).
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 information on NovAtel L-Band-capable antennas).
