CAVU Aerospace UK addresses these needs with a well-rounded product ecosystem that includes Onboard Computers (OBCs), Command and Data Handling (C&DH) systems, Thermal Control Units (TCUs), Solar Cells, and Panels. Each of these components plays a critical role in ensuring that space missions operate efficiently, safely, and with the resilience needed to withstand the challenges of the space environment. Here, we take a closer look at CAVU Aerospace UK’s product ecosystem and explore how these offerings are redefining the standards for space mission equipment.
Onboard Computers (OBCs)
Onboard Computers are the heart of any spacecraft, handling vital operations that range from navigation and control to communication and data processing. The demands placed on an OBC are immense, as it must operate reliably in harsh conditions, with minimal power, and under significant constraints. CAVU Aerospace UK has developed OBCs that emphasize redundancy, fault tolerance, and real-time processing capabilities, all of which are essential for the long-term success of space missions.
CAVU Aerospace UK‘s OBCs are meticulously designed to endure high radiation levels, extreme temperatures, and the intense vibrations of launch and space travel. These cutting-edge computers leverage a predominantly Flash-based FPGA SoC architecture, combining the parallel processing power of FPGAs with seamless software integration, enabling the use of straightforward C implementations without modification.
Equipped with advanced microprocessors integrated within the SoC, CAVU’s OBCs deliver fast processing speeds and adapt to diverse mission requirements. The inherent immunity of Flash-based FPGAs to Single Event Upsets (SEU) ensures robust reliability in radiation-prone environments, while their exceptionally low power consumption makes them ideal for space missions. Engineered for easy integration with spacecraft systems, these OBCs provide seamless functionality for communication, navigation, and control, enabling autonomous spacecraft responses to unexpected events and supporting mission-critical operations with unparalleled efficiency.
Command and Data Handling (C&DH)
CDH-1 – Satellite On-Board Command & Data Handling Subsystem with Redundancy
The Command and Data Handling (C&DH) system is critical for spacecraft operations, enabling seamless communication and control. It processes and distributes commands and data across subsystems while handling high data volumes with minimal latency and robust security. Built on a Flash-based FPGA SoC platform, it leverages MRAM, which, while radiation-prone, offers high-speed and non-volatile storage, and supports multiple boot options with TMR protection, ensuring fault tolerance and operational resilience.
The system’s modular and scalable design, powered by FPGA Fabric Logic, supports a wide range of interfaces, making it adaptable for various missions, from LEO to deep space. Additional features, such as onboard image and video encoding and compression, provide enhanced functionality for modern mission requirements. With redundant pathways and backup components, the C&DH system ensures uninterrupted operation even in challenging environments. CAVU’s C&DH systems deliver consistent data flow, secure communication with Earth, and robust performance, meeting the demands of advanced space exploration.
CDH-FS: Satellite On-Board Command & Data Handling Subsystem with Built-In Redundancy
The Command and Data Handling (C&DH) system is crucial for mission control and overall spacecraft operation. It is responsible for receiving, processing, and distributing commands and data among the various subsystems within the spacecraft. CAVU Aerospace UK’s C&DH system is designed to handle high volumes of data while ensuring minimal latency and robust security. This system forms the backbone of communication and control, enabling the spacecraft to respond to instructions from mission control on Earth.
CAVU’s C&DH systems are particularly noteworthy for their high degree of modularity and scalability. These features allow them to be tailored to different types of missions, from low Earth orbit (LEO) operations to deep space exploration. The C&DH units are also designed with a high degree of fault tolerance, employing redundant pathways and backup components to ensure that the system remains operational even in the event of hardware failures. The reliability of CAVU’s C&DH systems enables consistent data flow, maintaining clear communication with Earth and ensuring that all systems within the spacecraft function as intended.
Thermal Control Units (TCUs)
Space missions encounter extreme temperatures, with spacecraft moving from the scorching heat of direct sunlight to the intense cold of shadowed regions. CAVU Aerospace UK’s Thermal Control Units are designed to manage these temperature fluctuations, keeping sensitive equipment within safe operational limits. TCUs play a vital role in protecting electronic and mechanical components from damage caused by temperature extremes, which can severely impact the longevity and performance of the mission.
CAVU’s TCUs employ a combination of passive and active thermal control mechanisms. Passive control includes thermal coatings and insulation materials that help to reflect or absorb heat as needed. Active control mechanisms might involve heat pipes, radiators, and even heaters that distribute heat across the spacecraft to ensure consistent temperature regulation. By maintaining an optimal thermal environment, CAVU’s TCUs significantly enhance the reliability and durability of other onboard systems, ultimately supporting mission success even in the most extreme thermal conditions.
Solar Cells and Panels
One of the key challenges for any space mission is to generate sufficient power to operate all onboard systems. Solar power is the preferred solution, especially for missions closer to the Sun, where sunlight is readily available. CAVU Aerospace UK has developed high-efficiency solar cells and panels that convert sunlight into electrical energy to meet the spacecraft’s power needs.
The solar cells developed by CAVU are designed to be lightweight and flexible, allowing them to be deployed in compact and challenging spaces while still providing ample power. They are highly efficient in converting sunlight into electricity, even in lower light conditions, and are resistant to radiation damage, which is crucial for long-term missions. Additionally, CAVU’s solar panels are designed with modularity in mind, making it possible to expand or modify the panels according to the specific power requirements of the mission. These advanced solar technologies provide a reliable and sustainable power source, crucial for supporting a variety of mission functions.
