Overview

Our GPS/GNSS satellite simulators are easy to use, scenario-based instruments that combine a powerful, feature-rich platform with industry-leading value and affordability for any requirement for GPS testing.

Pendulum Instruments GSG series simulators generate the same RF signals that are broadcast by navigation satellites to test any device or system with a GPS receiver. Several different configurations are available but all are upgradeable to add capability as your needs for GPS testing grows.

Easy scenario-based testing

Test any condition with built-in or user-defined scenarios
Define trajectories:
- via a Google Maps interface
- in real-time from a data stream
- from recorded data
- and more
GSG StudioView Windows software makes creating, editing and managing scenarios simple
Test various impairments to the GPS signal including multi-path, interference, jamming, spoofing, atmospheric effects and more

Unprecedented convenience

Easy to set-up and operate
Compact and lightweight (~ 3 Kg / 6 lbs)
Standalone (front panel) operation or remote control via USB, Ethernet, GPIB
Just connect the RF cable to your receiver or set-up an over-the-air test with a radiating antenna in an RF shielded environment

Lowest cost-of-ownership

The standard for performance/price
Modular hardware/software platform protects your investment
Purchase only the features you need, upgrade when necessary; future GNSS signals fully supported

Key specifications

GSG-51 Single Channel GNSS Tester

The GSG-51 is a GNSS signal generator that emulates a single satellite signal. The main application is a simple but very fast manufacturing test, to assure that the assembly is correct, that the antenna is properly connected, and that the receiver can receive and identify a satellite signal.

GSG-5 Series Multi-channel Advanced GNSS Simulator

The GSG-5 series is a GPS, GLONASS, Galileo, BeiDou, and QZSS constellation simulator that generates all commercial signals in the standard L1 band.

GSG-6 Multi-Channel, Multi-Frequency Advanced GNSS Simulator

The GSG-6 Series family offers multiple frequency band operation, multiple GNSS constellation simulation, and expansion to many more channels.

GSG StudioView Software

GSG StudioView™ offers an easy way to create, edit and back-up complex scenarios for a Pendulum Instruments GSG series multi-channel GPS/GNSS simulator.
