Repeatable testing with the latest real-world signals

Field testing is a crucial stage in the development of any location-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. Spirent’s GSS6425 solves this problem.

Features & Benefits

Wide range of constellations supported
The GSS6425 can record and replay multiple frequencies from all global navigation satellite systems. It can capture GPS L1/L2/L5, GLONASS L1/L2/L3, Beidou-2 B1/B2/B3, Galileo E1/E1a/E5a/E5b/E6, QZSS L1/L2/L5, SBAS signals and services (Terrastar, Omnistar, StarFire).
Recreate rich real world environment
inside the lab
With 2 bit I\Q quantization GSS6425 can easily record 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.
Test in variety of applications
By recording data from external sources (sensor, inertial, CAN bus, up to 4 streams of video) synchronously with GNSS signals, various application areas can be developed or tested with GSS6425.
Highly portable and easy to use
Self-contained and simple to use, with one-touch recording and no need for an external PC. Can also be controlled over Wi-Fi using laptop, PDA or smartphone. Battery life of 1.5 hours.

Record and playback external data

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.

Remote control and automation

It is also possible to control the GSS6425 directly via the front panel keypad, or remotely via a web browser. Testing can also be automated, either by using simple HTTP commands, batch processing mode, or by executing test scripts on the unit’s on-board Linux platform.

Ready for the most demanding 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.

With a built-in battery lasting over 1.5 hours the GSS6425 is ideal for in-vehicle tests or portable operation with no fear of losing the data. The in-built OCXO ensures the recorded signals are not subject to unwanted noise.

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.

Why live signals could damage your brand

Reducing the time and cost of drive testing

Live drive testing is regarded as a cornerstone of best practice in the automotive industry, and ensuring the GPS positioning system is working accurately is a key part of this. Using the GSS6425, Spirent worked alongside one of the world's biggest auto manufacturers to help them improve the testing process by capturing real signals from a live drive test, and replay them repeatedly in the lab.
