Record real-world signals in even greater detail

RF record & playback systems enable you to repeat a real-world GNSS/GPS test run over and over in the lab. And with up to 16 bit quantisation, the Spirent GSS6450 lets you capture the most complex RF signal environments and interference in more detail than ever.

At just 216 x 200 x 76mm and 2.2kg, it’s easily the most portable system of its kind.

Features & Benefits

Built for the most demanding tests
The GSS6450 can record up to 4 RF signals in the 75MHz-6,000MHz frequency range - including any current GNSS signal, 2.4GHz and 5GHz WiFi, and Cellular. With the capability to record at up to 16 bits ‘I’ & 16 bits ‘Q’ and the flexibility to select up to 80MHz band within the frequency range, the GSS6450 can be configured to meet your testing requirements - even as they evolve.
Record – anytime, anywhere.
At 2.2kg the GSS6450 is easily the world’s smallest 16-bit RF record & playback system. It’s compact and light enough to be worn in a bag or over the shoulder – making it perfect for the advanced testing of wearable technology.
Upgrade as your needs change
The GSS6450 is designed to grow with your test needs. If you start with the base system, it’s easy to upgrade as your test requirements change.
More than just RF Recording
The GSS6450 can record up to 8 channels of synchronous data along with the GNSS. This can be either IMU, RTCM or CAN data. The data can then be replayed in synch with the GNSS.


Comprehensive RF record & playback

The GSS6450 supports a truly comprehensive range of GNSS constellations and signals: GPS L1, L2 and L5; Galileo E1, E5a\b and E6; GLONASS L1, L2 and L3; BeiDou B1, B2 and B3; QZSS L1, L2, L5 and L6; IRNSS L5 and S-Band. In addition, it supports 2.4GHz and 5GHz WiFi and LTE/Cellular.

Extended field sessions

Great for extended field sessions

With up to 2TB of internal storage – and up to 7.5TB more via removable SSD – you can record without interruption for longer.


Extreme flexibility

The GSS6450 can record up to 4 GNSS signals simultaneously, on a variety of bandwidths (10, 30, 50, 60 and 80 MHz) and bit depths (2, 4, 8, 16 ‘I’ and ‘Q’).

Easy to use

Supreme ease of use

We’ve built the GSS6450 to be simple to use, with a touch screen for easy setup, and an integrated GNSS receiver. If you want to automate the system, or simply control it remotely, you can do that too.

What bit depth do I need?

The bit depth required for effective record & playback testing is an important consideration, and can vary depending on the nature of your project. For more information have a read of our white paper.
