What does C&DH mean in NASA
Command and Data Handling (C&DH) is an important operational component of many government agencies and departments. C&DH systems play a key role in the operation of satellite, space and aviation systems, as well as other airborne, land-based and subsea operations. C&DH systems provide the essential control capabilities necessary to support complex missions. In addition to providing command control services, C&DH systems also incorporate data management functions to ensure that data is stored securely and efficiently while being available for critical decisions.

Definition
Command and Data Handling (C&DH) refers to the common set of processes used for performing multiple tasks across multiple platforms for a wide variety of operational requirements. These processes include commands (i.e., sending instructions from one system/platform to another), data processing (e.g., data compression, analysis), storage (e.g., databases), retrieval, monitoring, communication (e.g., transfer protocols) and decision making (i.e., using collected data to inform decisions). Through these processes, C&DH allows multiple platforms/systems working together simultaneously in order to monitor live activities or perform complex tasks autonomously without direct intervention by human operators.
Benefits
The use of C&DH systems provides numerous benefits to government operations including; increased mission assurance through automation; improved efficiency by reducing human error; reduced downtime due to mechanical failure; increased security through secure communications networks; improved coordination between multiple agencies; optimized resource utilization through predictive analytics; better decision making capabilities due to real-time data collection and analysis; as well as greater operational oversight through situational awareness tools which allow government personnel access to real time information about their environment and assets nearby in order to make informed decisions quickly.
Essential Questions and Answers on Command and Data Handling in "GOVERNMENTAL»NASA"
What is Command and Data Handling?
Command and Data Handling (C&DH) is the control system that directs a spacecraft's operations. It receives commands from Earth, interprets them, carries out appropriate actions and returns data to the ground.
What does the C&DH system do?
The C&DH system performs a wide variety of tasks including controlling and monitoring attitude, velocity, onboard systems status, power management, mission timeline management, navigation and communication.
How does C&DH handle commands?
Commands sent from Earth are received via radio frequency or optical connection. The C&DH system interprets these commands and executes them as appropriate for the current mission objectives.
How does C&DH handle data?
Data collected by the spacecraft's instruments or elsewhere is routed through the C&DH system for processing before being returned to Earth. Additionally, telemetry data such as onboard health information may be relayed in near-real-time to ensure smooth operation of the mission.
How reliable is C&DH?
C&DH systems must be extremely reliable as they are responsible for managing critical components of space missions. Redundant hardware and software features provide backup systems in case of failure while rigorous testing ensures their performance under a variety of conditions.
What type of strategies can be employed to improve reliability of C&DH system?
Strategies such as fault-tolerance mechanisms along with error detection algorithms can be employed to detect errors quickly and ensure continued reliable operation even when there are faults in the system or communications links are unreliable. Additionally, redundancy measures such as redundant hardware components can mitigate loss due to component failure over time.
Who designs and builds Command & Data Handling systems?
Specialized engineers collaborate together closely throughout all stages of a mission’s lifecycle - from conception through design, manufacture, assembly integration & testing (AI/T), launch and operational phases - to build functioning Command & Data Handling systems for various space missions across the world.
Is it cost effective to use a commercial off-the-shelf (COTS) platform for developing C& DH subsystems?
Yes! A Commercial off-the-shelf (COTS) platform offers flexibility over proprietary solutions since any updates or changes can be made easily without having to re-write code or rework existing hardware configurations. Thus using this solution reduces costs significantly compared to building customised solutions from scratch for each mission needs.
Final Words:
Government agencies rely on C&DH systems not only because they enable streamlined operations but also because they are cost effective over traditional approaches which require manual labor or significant capital investments in infrastructure or personnel training. By automating manual processes such as collecting data in remote locations or coordinating complex operations between departments across geographical boundaries, governments can reduce overhead costs while increasing accuracy and effectiveness of their operations overall. Thus Command & Data Handling is a critical technology for many government agencies ensuring effective mission performance with minimum effort and maximum results.
