Payloads refer to instruments, equipment, or systems that are onboard satellites designed to perform specialized functions, such as communication relays or scientific observations. By simulating various impairments and operational scenarios, hardware-in-the-loop testing comprehensively evaluates the performance and reliability of satellite payload components (e.g., transponders and antennas) under realistic conditions. Hardware-induced distortions that can be emulated with the ACE9600 include signal compression, intermodulation distortion, AM/PM distortion, phase noise, group delay slope, amplitude slope, and passband notching to simulate different countries regulatory spectrum requirements.
Real-world hardware impairments, simulated in the lab
Hardware-influenced impairments from your ground station or satellite payload can significantly impact performance. With hardware-in-the-loop testing, you can uncover potential system faults and verify performance in post-deployment conditions long before launch.
Maury channel emulators bring realistic conditions to payload and ground station testing, replicating various, real-time hardware impairments in a controlled laboratory environment.
Maury solutions support:
- Accurate, advanced emulation of hardware-generated impairments to assess system readiness.
- Early detection of system vulnerabilities under realistic operating conditions.
- Optimize system development with comprehensive performance evaluation.
Maury empowers leading satellite system innovators to strengthen reliability, mitigate risks, and accelerate development timelines with advanced hardware-in-the-loop channel emulation solutions.
Payload testing to ensure mission readiness
Optimize ground station systems for post-deployment challenges
Ground stations facilitate the exchange of data between in-orbit satellites and terrestrial networks, track and monitor satellite operations, and provide mission-support services, among other critical tasks for satellite communications systems. Ground station hardware-in-the-loop testing emulates various hardware-induced impairments to assess the system’s response to challenging post-deployment conditions. Simulated impairments available with the ACE9600 include signal compression, intermodulation distortion, AM/PM distortion, phase noise, group delay slope, and amplitude slope.
