Information About GSG-51
The GSG-51 is part of the Spectracom GSG 5 Series and serves as a compact GNSS signal simulator supporting GPS L1C/A and SBAS signals. Operating on 100–240 V AC input power, it provides a wide output power range from –65 dBm to –160 dBm, making it suitable for both conducted and over-the-air testing. The device features a BNC or N-type RF output connector and supports communication via USB, GPIB, and Ethernet interfaces. It is user-configurable through a front-panel display without the need for external software, and offers continuous simulation up to 31 days. The GSG-51 is upgradeable post-purchase, allowing users to expand channel count or add features like multipath simulation and white noise generation.
Key Features:
- Single GNSS Channel: Simulates one GNSS satellite signal for production and verification tests.
- Wide Output Power Range: Adjustable from –65 to –160 dBm for all receiver sensitivity levels.
- Multi-System Support: Outputs GPS L1C/A, SBAS (WAAS, EGNOS, MSAS, GAGAN), and compatible frames.
- Front Panel Configuration: Modify satellite ID, time, and power without a PC or precompilation.
- Multiple Interfaces: Communicates over USB, GPIB, and Ethernet for flexible integration.
- Upgrade Capability: Channel count and advanced features can be added after purchase.
- Long-Term Simulation: Operates continuously for up to 31 days (or indefinitely with network).
- Affordable Entry-Level Unit: Provides an efficient solution for GNSS receiver manufacturers.
The GSG-51 delivers the accuracy, programmability, and flexibility required for fast and reliable GNSS production testing.
