Enabling L-Band
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
www.novatel.com/products/gnss-antennas
for information on NovAtel
L-Band-capable antennas).
For more information on L-Band positioning, refer to:

NovAtel CORRECT™ with TerraStar
A subscription is required to use the TerraStar service. To obtain a subscription, contact your local
NovAtel sales representative or visit
http://www.novatel.com/products/terrastar-gnss-corrections/
. The
receiver’s TerraStar Product Activation Code (PAC) or the NovAtel product serial number (PSN) is
needed to obtain a subscription. To obtain the receiver-specific PAC, enter the following command:
log terrastarinfo
This log displays the PAC in the first field following the log header and also displays the status of your
subscription.
To activate a subscription, the receiver must be powered and tracking an L-Band TerraStar satellite prior
to the planned activation time. Use the
ASSIGNLBANDBEAM
command to configure the receiver to track
the TerraStar satellite.
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 Transition.
C
The solution accuracy exceeds the warning limit. The position type changes to
OUT_OF_BOUNDS.
Steadyline is disabled.
