LOGGING DATA
An extensive collection of logs has been created to capture the
data your FlexPak receives and processes. These logs can be
directed to any of the FlexPak’s serial ports and can be
automatically generated when new or changed data becomes
available or at regular intervals. The available logs are listed in
the OEMV Family Quick Reference Guide.
To log data, use the LOG command. For example, to log the
pseudorange position to COM 2 every 30 seconds, enter the
following:
LOG COM2 PSRPOS ONTIME 30
Logs can be generated in one of three formats: ASCII,
Abbreviated ASCII, or Binary. Refer to the OEMV Family
Firmware Reference Manual (OM-20000094) for information on
the LOG command, specifying the output format, and the
detailed contents of each log.
If you prefer, CDU provides a graphical interface for configuring
data logging. Select Logging Control Window from the Tools
menu. In the Logging Control window, you can select which logs
to capture and choose to which ports to send the data. In
addition, you can specify a file in which to save the data.
ENABLING SBAS POSITIONING
FlexPak-V1/V1G/V2 models are also capable of SBAS
positioning. This positioning mode is enabled using the
SBASCONTROL command. The following commands are typically
used to enable WAAS (North America) and EGNOS (Europe)
respectively:
SBASCONTROL ENABLE WAAS
SBASCONTROL ENABLE EGNOS
Once enabled, the Position Type field shown in CDU’s Position
window should change from Single to WAAS and you may see
SBAS satellites in the Constellation window.
ENABLING L-BAND POSITIONING (FlexPak-V1 only)
L-Band equipped receivers allow you to achieve sub-meter
accuracy. To use this positioning mode, you must enable L-band
tracking to the Canada-Wide Differential GPS (CDGPS) or
OmniSTAR signal. A subscription to OmniSTAR is required to
use the OmniSTAR service (visit http://www.omnistar.com
and
have your receiver’s serial number ready). The CDGPS signal is
free and available without subscription over North America (visit
http://www.cdgps.com
).
The ASSIGNLBAND command allows you to set OmniSTAR or
CDGPS base station communication parameters. It should
include a relevant frequency and data rate. 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.
To confirm you are tracking an L-Band signal, log the L-Band
status information by entering:
log lbandstat
For example, if you are receiving CDGPS, the fifth field after the
header should be 00c2:
lbandstata com1 0 43.5 finesteering 1295
149951.671 00000000 976f 34461;
1547546977 46.18 4541.0 0.00 00c2 00f0 ...
To specify the correction source, use the PSRDIFFSOURCE
command as shown in the examples below:
PSRDIFFSOURCE OMNISSTAR or,
PSRDIFFSOURCE CDGPS
otherwise it is left at the default AUTOMATIC.
Refer to the OEMV Family Firmware Reference Manual for more
on individual L-Band (FlexPak-V1 only), GLONASS (FlexPak-V1G
or FlexPak-V2) or SBAS commands and logs.
