More with LabSat 4

LabSat 4 not only offers exceptional performance but also stands out for its ease of use, compact design, and remarkable cost efficiency. With free lifetime support and firmware upgrades, it provides unmatched value and reliability.

Features

Performance

Simultaneously record up to 3 GNSS channels, each with a 10-60 MHz variable bandwidth and up to 12-bit quantization.

Multi-Constellation & Multi-frequency

Record & Replay all GNSS signals in the Upper and Lower L-Band, including SBAS and Commercial differential services.

High Speed Data Transfer

Efficient file management is delivered via high-speed data transfer to and from the 7.6 TB internal storage via Gigabit Ethernet and USB 3.

Multi-System Synchronisation

Tightly synchronise the Record & Replay of two LabSat 4 systems, ideal for dual antenna testing.

API Available

Use API and Ethernet connectivity to automate test programmes, deliver global testing from a centralised point, and seamlessly integrate with wider test set-ups.

Additional Signals

Record a range of additional signals synchronised to the GNSS input, such as dual-CAN, CAN-FD, RS232, and digital signals.

Conducted or Radiated Testing

Test a device with an internal antenna via radiated testing or a device with an external RF connection using conducted testing.

Expand Testing with SatGen Software

Add simulation to your LabSat with SatGen - create bespoke, high-dynamic scenarios at the time, date, and location of your choosing.

Why LabSat?

Performance

Key to LabSat 4 are its three RF channels, each configurable with up to 12-bit I&Q quantization and a bandwidth of up to 60 MHz. This flexibility enables engineers to precisely control recording parameters and optimize file sizes for specific testing requirements.

The 12-bit recording capability allows LabSat 4 to capture realistic, high-resolution scenarios, even under challenging conditions such as low signal strength, multipath effects, interference, and spoofing attacks.

Additionally, synchronized record and replay of external data sources - such as CAN, CAN-FD, RS232, and digital event capture - further enhance its ability to simulate complex test scenarios with accuracy and reliability.

Ease of Use Anywhere

Using a LabSat requires no special training, thanks to its intuitive design and straightforward operation. Simple navigation on the unit and a user-friendly web interface make configuring tests effortless.

The one-touch Record & Replay feature allows users to start and stop recordings with a single button press, ensuring convenience and efficiency.

LabSat 4 comes with a selection of preloaded scenario recordings, enabling testing straight out of the box.

Compact, portable, and battery-powered, LabSat simulators are perfect for live-sky recording in any conditions. Their small size also makes them ideal for integration into standard rack mounts as part of a broader testing setup.

Budget-friendly

Using recorded GNSS data for testing reduces the need for repetitive field-testing and saves both time and costs. LabSat was born out of a need for an easy to use and cost-effective GNSS simulator and over 25 years later, it maintains not only its ease of use, but also its highly competitive pricing.

Lifetime Support

All LabSat owners benefit from exceptional customer support that is provided free of charge with no support contracts. All future firmware and software updates are also provided for free so that owners continue to have access to all the latest features and upgrades.
