Why LABSAT 4 IS DIFFERENT
Real sky signal. Not a mathematical model.
Most GPS and GNSS simulators generate synthetic signals from mathematical models. LabSat 4 takes a different approach.
Synthetic simulators
Mathematically modelled signals
Signals computed from orbital models — they approximate reality, not reproduce it
Multipath, atmospheric effects, and interference must be manually configured
Edge cases that only occur in real environments are difficult to reproduce synthetically
High complexity and cost to set up scenarios with realistic signal environments
VS
LabSat 4
Captured real-world RF — replayed with 12-bit fidelity
Actual RF signals from live sky, exactly as your device will encounter them in the field
Real multipath, real atmospheric conditions, real interference — nothing is approximated
Edge cases and fault scenarios are captured once, replayed identically — indefinitely
For device validation, regression testing, and production test: a more representative signal environment than any synthetic model can produce
When LabSat 4 replays a scenario, your device responds to the same RF it would see in that exact location, at that exact time – not a simulation of it. For regression testing and production validation, that distinction matters.
THE CHALLENGE
Field testing is costly, slow, and impossible to repeat exactly
Every time you need to validate a GNSS device against a specific signal scenario (weak urban signals, multipath, SBAS corrections), you face the same problem: go back to the field, or accept a test gap.
Repetitive field trips
L2, L5 and SBAS coverage gaps
Inconsistent test conditions
CAPABILITIES
Built for engineers who need precise, repeatable results
3 independently configurable RF channels
Each channel has its own centre frequency, bandwidth (10 to 60 MHz), and quantisation (up to 12-bit I&Q). Record any combination of GNSS signals simultaneously.
API and Ethernet automation
Automate test sequences, run continuous overnight programmes without supervision, and control multiple units from a central office, including global production sites.
Synchronised additional signal logging
Log dual-CAN, CAN-FD, RS232, digital inputs, and RTK correction data in sync with GNSS RF. Essential for automotive and autonomous vehicle testing.
Multi-unit synchronisation for dual-antenna testing
Connect two LabSat 4 units via the Dual Sync Cable for precisely synchronised record and replay. Critical for heading and attitude applications.
Real-time simulation with SatGen
Generate custom GNSS RF scenarios, static or dynamic, and stream them live with current UTC time. No pre-recorded file needed for SatGen-powered tests.
Conducted or radiated testing
Direct RF output to devices with external antenna ports, or use radiated testing with the LabSat Test Enclosure for devices with internal antennas, including wearables.
