Device Now Has GPS L5 and GALILEO E5 Simulation Capabilities
Rohde & Schwarz has added GPS L5 and GALILEO E5 simulation capabilities to the SMW200A GNSS simulator, the company announced on 19 September.
Since its launch in 2017, the SMW200A has been the world’s first and only general-purpose vector signal generator that can be turned into a high-end GNSS simulator and is able to internally simulate complex interference environments in parallel with GNSS signals. This unique test solution has now been further enhanced by adding simulation capabilities for the L5/E5 frequency band.
An increasing number of GNSS receivers are capable of receiving signals on multiple frequencies, such as L1, L2 and L5. Although this multi-frequency capability, as well as having to process signals from diverse navigation systems such as GPS, GLONASS, GALILEO or BeiDou, make the receiver design more complex, they ensure a better quality of service for the end user. Multi-frequency and multi-constellation processing not only improve positioning accuracy, service availability and robustness, they also make the positioning process less vulnerable to interference, jamming or spoofing attacks.
The SMW200A GNSS simulator is the ideal tool for efficient test and characterisation of multi-constellation and multi-frequency GNSS receivers. With its recently added simulation capabilities for GPS L5 and Galileo E5, the device makes it easy to generate complex and highly realistic test scenarios with up to 144 channels in GNSS frequency bands L1, L2 and L5. In addition to GPS (L1/L2/L5), GLONASS (L1/L2), GALILEO (E1/E5) and BeiDou (L1/L2), the SMW200A also supports signal generation for QZSS and SBAS on L1. The available channels can be routed to up to four RF outputs, so that even multi-antenna systems can be tested.
Apart from its new GNSS simulation capabilities, the SMW200A remains the first and only vector signal generator that can generate complex coexistence and interference scenarios with multiple interferers: GNSS signals, noise and all interference signals are generated directly in the instrument. Additional sources for external generation of interference signals are not required, resulting in small, compact and simple test setups.
