主要特性與技術指標
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.
