2.
Run the recorded trajectory through the
Scenario Generator
in StudioView. Note
that your StudioView computer must be connected to the GSG unit, and that the
OPT-RP option must be enabled.
StudioView will automatically generate the scenario, event and trajectory files for
you.
3.
Upload
the generated scenario files to your GSG unit, and playback the scenario.
4.9.14.2 Installation of the OPT-RP Software
From the GSG Software CD, copy the file
setup_vx.x.exe
to your PC. Run the execut-
able to install the Record and Playback software.
4.9.14.3 Usage Notes
i.
The Record and Playback software is intended for use with a properly licensed GSG.
If your GSG needs a Record and Playback license, please contact Orolia (see
).
ii.
The Record and Playback program uses the GSG VISA address to check for a valid
license file. This address is also used to upload the results to the GSG if the
Auto
upload
feature is enabled. GSG supports communication via TCP/IP, USB, and GPIB.
For TCP/IP connections, this program will accept IPv4 addresses as well as VISA
resource strings. The following lines describe the resource name syntax.
iii.
VISA resource string format:
TCPIP[board]::host address[::LAN device name][::INSTR]
USB[board]::manufacturer ID::model code::serial number[::USB
interface number][::INSTR]
GPIB[board]::primary address[::GPIB secondary address]
[::INSTR]
For more information about the VISA address, please see:

address/

The signal
‐
to
‐
noise ratio (SNR) is used to compare the level of a desired signal to the
level of background noise. The SNR is expressed in decibels (dB) and is used to
describe the GNSS signal strength in NMEA
‐
0183 GSV sentences.
v.
On the GSG unit, signal strength is specified in dBm, i.e. the power ratio in decibels
of the measured power referenced to one milliwatt (mW). Since dB cannot be dir-
ectly converted into dBm, the Record and Playback program relies on a decibel off-
set value. This offset value maps the NMEA signal strength (in dB) to the GSG signal
