INTRODUCTION
The OBC1 onboard computer is designed with redundancy in mind, capable of operating in a configuration with another OBC1 board to ensure continuous and reliable performance. To enhance this redundancy, we introduce the OBC1-Supervisor. This essential component monitors and manages the active OBC1 boards, ensuring seamless operation and automatic recovery in case of malfunctions. The OBC1-Supervisor employs high-reliability logic circuits, making it a critical addition to mission-critical applications where uninterrupted operation is paramount.
KEY FEATURES
- High-Reliability Logic Circuits: Utilizes Flash-based Actel FPGA without any processors, ensuring minimal failure points and robust performance.
- Redundancy Management: Capable of configuring two OBC1 boards in a redundant topology, automatically switching between active boards in case of a malfunction.
- Automatic Recovery Procedures: Efficient automatic recovery protocols to bring the faulty OBC1 board back online.
- Current and I/O Monitoring: Monitors current and I/O control signals to detect and address issues promptly.
- Pure Logic Monitoring Sequence: Runs monitoring sequences on pure logic, eliminating the need for software and enhancing reliability.
- Enhanced Mission Reliability: Significantly increases the reliability of the OBC1 system, making it suitable for critical space missions.
TECHNICAL ADVANTAGES
The OBC1-Supervisor offers several technical advantages, making it a superior choice for enhancing the reliability of OBC1 systems:
