主要特性与技术指标
Spirent’s next-generation Record and
Playback system (RPS) simplifies,
accelerates and enhances the field testing
of Multi-GNSS receivers and devices, and
integrated, hybrid positioning systems.
The GSS6425 is a highly portable system
for recording live GPS L1/L2/L5, GLONASS
L1/L2/L3, Beidou-2 B1/B2/B3, Galileo E1/E5
, QZSS L1/L2/L5 and SBAS signals in the
field—for repeated replay in the lab.
Building on our success with GSS6400 RPS
system, GSS6425 with its new architecture
and design packs even more powerful
features—including more channels,
increased bandwidth and up to 2TB of data
storage.
Repeatable Testing with the Latest Real-
World Signals
Field testing is a crucial stage in the
development of any GNSS-enabled
technology. Testing with live signals is
slow, expensive and limited since the
ever-changing nature of the natural
radio-frequency (RF) environment makes it
impossible to run exactly the same test
twice.
The Spirent GSS6425 RPS quickly and simply
records complex real-world RF
environments, capturing both GNSS signals
and atmospheric/interference effects.
These environments can then be replayed
repeatedly to the hardware or software
under test:
Enabling rigorous, comparative testing
Reducing project, travel and engineering
costs
Improving performance, quality and time to
market
Record and Playback External Data
In addition to RF signals, the Spirent
GSS6425 RPS can record and replay serial
data from a wide range of external data
sources.
Inertial sensors, DR sensors, reference
receivers, 1pps and CAN bus data can all
be recorded coherently—for synchronous or
asynchronous playback—or logged for
analysis and post-processing. An optional
accessory can be purchased to enable
advanced CAN bus features such as CAN Bus
arbitration during playback, smart
decoding & filtering, condition based
logging and simulation of CAN traffic &
messages.
Video streams can also be recorded
synchronously with GNSS signals by simply
connecting up to four webcams, and
replayed for a visual record of the
location. This helps during post
processing and for optimizing receiver
performance in challenging conditions such
as multi-level roads, entry/exit points of
tunnels, and dense urban environments.
Remote Control and Automation
The GSS6425 RPS can easily be controlled
from a laptop, PDA or tablet over Wi-Fi by
connecting a USB Wi-Fi dongle.
It is also possible to control the GSS6425
directly via the front panel keypad, or
remoy via a web browser. Testing can
also be automated, either by using simple
HTTP commands, or by executing test
scripts on the unit’s on-board Linux
platform.
Ready for the Most Demanding Applications
The advanced capabilities of the GSS6425
RPS make it an ideal solution for testing
GNSS receivers and devices for automotive,
navigation, aerospace, defence and survey
applications.
The GSS6425 supports USB 3.0, enabling
longer recording times by recording
directly to an external hard drive, the
size of which being the only limiting
factor with respect to record times. Data
recording time can run for days, or even
weeks.
Live Sky Data Set
To further reduce testing costs and time
to market, GSS6425 RPS users can take
advantage of our live sky data sets, a
library of pre-recorded RF environments,
captured by our experts at a range of key
locations worldwide.
With the GSS6425 available in Record
\Replay or Replay only variants (L1 only
and L1\L2\L5), you can choose to process
all GNSS signals in L1, L2 and L5 bands
with its three record-and-playback
channels.
优势

of GNSS signals in optimum fidelity
Complete even lengthy field recordings
without interruption, with a 1TB internal
hard drive and 1TB removable hard drive
Record 3 RF frequencies at any one time
with 30MHz bandwidth—or reduce bandwidth
to 10MHz, for even longer recording
sessions
Increasing recording of frequencies to 6
by synchronizing two GSS6425 units in
master/slave configuration
Record and replay (synchronously or
asynchronously) up to six channels of data
from external sources (e.g., NMEA truth
data, INS, 1PPS etc.)
Record and replay synchronously up to 4
video streams by simply connecting webcams
on the USB ports
Apply attenuation on all or individual
channels
Control and monitor record and playback
remoy, using the unit’s built-in
webserver, even over Wi-Fi
Save time by automating testing with HTTP
commands, or by executing test scripts on
the unit’s on-board Linux platform
Fast connection to external devices using
two USB 3.0 ports
Simple, Powerful and Versatile
Self-contained and simple to use, with
one-touch recording and no need for an
external PC
Can also be controlled wirelessly using
laptop, PDA or smartphone (optional)
Built for easy integration with other test
systems
Accurate, efficient and cost-effective
Accuray record and playback RF
environments including real-world
impairments (such as atmospheric effects,
multipath, fades and interference)
Present exactly the same recorded real-
world signals to any number of devices
under test, whenever and wherever is
convenient—reducing field test costs and
increasing productivity
