Validate satellite performance with cross-domain automated simulation

Validating satellite system performance with efficient preorbital testing requires end-to-end characterization, improved satellite simulation, and hardware-in-the-loop development. By integrating these methodologies, engineers can ensure robust system reliability and optimize satellite functionality before deployment. The end-to-end digital network and analog RF satellite system simulator includes modeling and test automation software, a signal analyzer, and a signal generator that supports a cohesive ecosystem for all stages of satellite system development. Test automation software orchestrates all instruments and applications while automating the test setup and measurement execution.

Network modeling software duplicates communication satellite network objects, emulating network characteristics, network traffic, and the associated physical transport environment. The network emulator then enables a comprehensive simulation and examination of satellite traffic and digital data streams while undergoing impairments. After the satellite modem converts these signals into RF energy, the channel emulator replicates realistic, real-time, dynamic radio channel scenarios. The signal generator and signal analyzer then provide complex signal performance analysis.

Preorbital satellite performance testing solution

Validating satellite system performance requires end-to-end testing and automation that provides a cohesive ecosystem to enhance development efficiency and satellite performance. The Keysight end-to-end digital network and analog RF satellite system simulator uses Keysight Eggplant test automation software to coordinate the test execution, simplify complex coding, and automate repetitive tasks.

Keysight IxChariot software and the Keysight Network Emulator II work together to deliver real-world scenario simulation. This combination enables the introduction of network impairments to help ensure the network's robustness and reliability. The Keysight PROPSIM channel emulator models the radio channels between transmitters and receivers in real time, providing a realistic testing environment for RF communication signal optimization. To simulate and analyze interference, the Keysight MXG vector signal generator and Keysight UXA signal analyzer generate and examine fast-hopping, wideband, and transient signals.
