Spirent Communications
The world’s leading provider of GNSS test and simulation systems
Spirent is the world’s leading provider of GNSS test and simulation systems. Over the past few years Spirent has developed new systems for testing modernized GPS signals, all Galileo signals and services, augmentation systems, Assisted-GPS in mobile devices, in vehicle navigation systems (IVNS), aircraft landing systems, adaptive antennas, inertial navigation systems (INS), classified military navigation signals and multi-GNSS platforms.
What is a GPS/GNSS Simulator?
Global Navigation Satellite System (GNSS) is a general term for a system that provides navigation and other services to users worldwide. Each GNSS employs a constellation of satellites, which broadcasts signals processed by GNSS receivers to determine location, speed, and time for users anywhere in the world. Examples of GNSS include GPS, GLONASS, and Galileo.
A GPS/GNSS simulator provides an effective and efficient means of testing GNSS receivers and the systems that rely on them. A GPS/GNSS simulator provides control over the signals generated by GNSS constellations and over the global test environment all within a box, so that testing can be conducted in controlled laboratory conditions. GPS/GNSS simulators generate the same kinds of signals transmitted by GNSS satellites, thus GNSS receivers process the simulated signals in exactly the same way as signals from actual satellites.
Why are we talking about Multi GNSS?
Navigation and positioning technology is no longer just about GPS L1 C/A code. GPS is being modernized, the GLONASS constellation is nearly complete, new systems including QZSS, Galileo and Compass are on the way.
Spirent Multi-GNSS Test Systems
Spirent offers a wide range of test systems and capabilities to meet your Multi-GNSS test needs. Our Multi-GNSS systems are designed with future development in mind and are expandable to address tomorrow’s test requirements as well as today’s. Whether you are undertaking R&D performance testing, integrating devices into your product line, verifying performance or assessing manufacture of Multi-GNSS devices, Spirent has a Multi-GNSS test system available today to match your needs.
The GSS8000 Multi-GNSS Constellation Simulator; Up to three RF carriers, selected from a range of constellations and signals (GPS, Galileo, GLONASS and Quazi Zenith Satellite System), can be accommodated in a single signal generator chassis. This enables multiple signals from a single constellation or hybrid systems with signals from multiple constellations to be tested. The architecture supports future Compass signals.
The GSS6700 Multi-GNSS Simulation System offers up to 36 channels of combined GPS/SBAS, GLONASS and Galileo L1 signals from a single chassis, 12 channels for each constellation. The GSS6700 is available with one, two or three constellations enabled. Different software capabilities and flexibility are available to suit different test needs. For existing Spirent STR4500 or GSS6560 customers who today test GPS/SBAS L1 only, the GSS6700 offers the ability to simulate not only GPS/SBAS but also GLONASS and Galileo.
The GSS6300 Multi-GNSS Signal Generator is designed specifically for production test applications where a single channel is required for controlled GNSS testing. The GSS6300 can generate a single, combined GPS/SBAS, GLONASS and Galileo signal to enable testing of GPS only or Multi-GNSS devices in a production environment. In addition, the GSS6300 offers the benefit of on-site (even in-rack) upgradability to add GLONASS and Galileo generation capability concurrently with GPS/SBAS.
