4.5 Enabling SBAS Positioning
All OEMV family receivers are capable of SBAS positioning. This positioning mode is enabled using
the SBASCONTROL command. EGNOS at one time used the IGNOREZERO test mode. At the time
of printing, ZEROTOTWO is the correct setting for all SBAS, including EGNOS, running in test
mode. On a simulator, you may want to leave this parameter off or specify NONE explicitly. As a
result, the following commands are typically used to enable WAAS and other SBAS modes, for
example EGNOS, respectively:
sbascontrol enable waas
sbascontrol enable egnos 0 zerototwo
See Section 5.2, Satellite-Based Augmentation System (SBAS) on Page 78 for more information.
4.6 Enabling L-Band (OEMV-1, OEMV-1G, OEMV-3, DL-V3 & ProPak-V3)
L-Band equipped receivers allow you to achieve sub-meter accuracy. In order to use this positioning
mode, you must enable L-band tracking to the Canada-Wide Differential Global Positioning System
(CDGPS) or OmniSTAR signal. A subscription to OmniSTAR is required to use the OmniSTAR
service. The CDGPS signal is free and available without subscription (a CDGPS coverage map is
shown in Figure 28 on Page 87).
To obtain an OmniSTAR subscription, contact OmniSTAR at 1-800-338-9178 or 713-785-5850. If
you contact OmniSTAR, you will be asked to provide the receiver’s OmniSTAR serial number (which
is different from the NovAtel serial number). To obtain the OmniSTAR serial number, enter the
following command in a terminal window or the Console window in CDU:
log lbandinfo
The log that is generated displays the L-Band serial number in the fifth field following the log header.
It is a six digit number in the range 700000 to 799999. This log also provides the status of your
subscription. Refer to the LBANDINFO command for more information.
In order to activate an OmniSTAR subscription, the receiver must be powered and tracking an L-Band
satellite. When advised by OmniSTAR of the appropriate satellite frequency and data link rate for
your location, use the ASSIGNLBAND command to configure your receiver. The CDGPS frequencies
are on Page 86 and these can also be used with the ASSIGNLBAND command. Below are examples
for using either CDGPS and OmniSTAR:
assignlband cdgps 1547547 4800
assignlband omnistar 1536782 1200
 1. In addition to a NovAtel receiver with L-Band capability, a subscription to the
OmniSTAR, or use of the free CDGPS, service is required. Contact NovAtel for details.
2. The frequency assignment can be made in Hz or kHz. For example:
Hz: assignlband omnistar 1536782000 1200
kHz: assignlband omnistar 1536782 1200
A value entered in Hz is rounded to the nearest 500 Hz.
