Spectracom GSG-51

Single-channel GPS/GNSS L1 RF Generator

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.

It provides a fast and cost-effective solution for production test of GNSS-receivers in e.g. mobile phones with integrated GNSS-receivers.

Thanks to the wide RF level range from –65 to –160 dBm, the sensitivity of all types of GNSS receivers can be verified with a minimum of delay.

The 60 dB of extra power from normal test scenarios allows for splitting the signal many times.


Spectracom GSG-5 Series

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

Incorporating all of the features of the popular 5 Series family, the 6 Series line expands your capability to simulate all the new, emerging GNSS signals.

With a base of 32 channels, upgradable to 48, 64, or more, it provides navigational fix and position testing, for engineering and development testing.

The 6 Series simulator protects your investment by being upgradeable in the future to more frequency bands and channels (plug-in hardware upgrade) and more signal formats (firmware upgrade).

Advanced Multi-Simulator Systems

GSG Series GPS simulators are exquisitly synchronized to accurately generate constellations of global navigation satellites, and other signals, through its single multi-channel output, which opens up more opportunity.

The benefit of accurately timed signals is the ability to synchronize several units to construct advanced test systems and pseudolite-like infrastructure.

  • Multiple RF outputs can be combined to create rich test environments with hundreds of signals.
  • Create tests for controlled radiation pattern arrays by generating direction-specific signals.
  • Test resiliency against spoofing scenarios where one unit is simulating live sky and another is attempting a take-over of GPS navigation.
  • Generate live sky GPS signals to act as an intelligent repeater system for a GPS-denied environment. 

 

Capabilities for Synchronisation

For Advanced Test Systems

  • Each simulator's high quality crystal oscillator can be synchronized to a common precise 10 MHz reference clock via an external input.
  • A common trigger pulse synchronizes the start of the test scenarios across multiple units.

For Synchronization to Live Sky

  • A "Simulate Now" feature synchronizes to the exact date and time by an NTP server, and...
  • Downloads and uses the same satellite ephemeris data as being broadcast in the GPS message.

GNSS Vulnerability Test System

Understanding the reaction of GPS-based navigation in various spoofing scenarios is the key to hardening the system against spoofing attacks.

The threats to GPS-based navigation systems are ever-increasing. The risk of intentional disruption of GPS signals is moving from simple jamming to a much higher-level of sophistication.

Spoofing— an attempt to deceive by broadcasting false GPS signals — can be devastating, leading to loss of assets or, worse, lives.

While testing the sensitivity to jamming is basic functionality of GPS simulators, measuring the effects of various spoofing scenarios requires a high degree of complexity.

Spectracom is at the forefront of testing the vulnerabilities of GPS-based navigation and now offers its capability as a GNSS Vulnerability Test System.
