The Role of Helium in Commercial Space

Helium plays multiple critical roles in the space sector, largely due to its unique properties such as chemical inertness, extremely low boiling point, and high diffusivity.

Satellite OBC Selection Guide (XII): Conclusion – Core Logic and Summary of OBC Selection

The On-Board Computer (OBC) is the "brain" of a satellite, and its selection directly determines the satellite’s reliability, mission execution capability, and cost.

Satellite OBC Selection Guide (XI): Sensor Requirements – Matching Mission and System Monitoring Needs

Sensors onboard satellites (e.g., cameras, gyroscopes, temperature sensors) are the core of "mission data collection" and "system health monitoring."

Satellite OBC Selection Guide (X): Space Heritage – Ensuring Reliability and Maturity

"Space Heritage" refers to an OBC’s number of completed on-orbit missions, fault-free operation time, and practical application cases.

Satellite OBC Selection Guide (IX): Compliance Testing – Verifying Space Environment Adaptabilit

Before delivery, the OBC must pass "compliance testing" — simulating the full-cycle environmental stress of the satellite from launch to on-orbit operation, verifying its resistance to the space environment, and ensuring compliance with aerospace standards (e.g., ECSS, MIL-STD).

Satellite OBC Selection Guide (VIII): Static and Dynamic Memory Sizes – Matching Software and Data Storage Requirements

OBC memory is divided into "dynamic memory (RAM, temporary storage)" and "static memory (e.g., ROM, flash memory, permanent storage)".

Satellite OBC Selection Guide (VII): Fault Tolerance – Addressing Failures Caused by Space Radiation

Radiation in the space environment (e.g., cosmic rays, solar protons) can trigger "Single Event Effects (SEE)" in OBC electronic components — including faults such as Single Event Upset (SEU, memory data errors), Single Event Latchup (SEL, component burnout), and Single Event Functional Interruption (SEFI, logic errors).

Satellite OBC Selection Guide (VI): Interface Requirements – Ensuring Compatibility with Subsystems

As the "data hub" of a satellite, the OBC needs to interact with multiple subsystems such as attitude control systems, sensors, communication modules, and power supply systems.

Satellite OBC Selection Guide (V): Computing Power – Matching Data Processing and Transmission Efficiency

The communication window between a satellite and a ground station is extremely short (usually only 3-10 minutes).
