How to Choose the Right Command & Data Handling (C&DH) System for SmallSats

Choosing the right Command & Data Handling (C&DH) system for your SmallSat mission is critical to ensuring smooth mission operations. The C&DH system is responsible for managing data flows, executing commands, and overseeing the health of the satellite. 

Here’s how to approach selecting the best solution:

1. Assess Mission Requirements

Your mission’s goals will dictate the C&DH system you need. Consider factors such as data throughput, power consumption, real-time command processing, and memory capacity. For more complex missions involving higher data volumes (such as Earth observation), opt for systems with larger storage and faster processing capabilities.

2. Reliability & Redundancy

In space, reliability is non-negotiable. Look for a C&DH system with built-in redundancy, meaning it has backup components that kick in if the primary systems fail. This ensures mission continuity, especially for long-duration missions.

3. Scalability & Flexibility

Select a C&DH system that can scale with your mission’s needs. Whether you're starting with a simple test flight or planning a more advanced multi-sensor mission, the system should be flexible enough to adapt to changes or upgrades.

4. Data Handling Capabilities

Different missions require varying levels of data handling. For example, scientific missions collecting large amounts of sensor data may need robust data storage and compression capabilities. Understanding your data needs will guide you toward the right C&DH configuration.

5. Environmental Considerations

Your spacecraft will face harsh conditions, including radiation and temperature extremes. Ensure your C&DH system is rated to withstand these challenges without degradation in performance.

By carefully evaluating these factors, you can choose a Command & Data Handling system that ensures the success of your mission, from launch to completion. Explore a range of vetted C&DH systems in our SmallSat Catalog, where reliability meets innovation.
