How do you communicate and visualize spaceflight trajectory optimization results to different stakeholders?

由人工智能和领英社区提供技术支持

Spaceflight trajectory optimization is the process of finding the best path and control inputs for a spacecraft to achieve a desired mission objective, such as orbit insertion, rendezvous, or landing. It is a complex and challenging task that involves mathematical models, numerical methods, and computational tools. However, optimizing a trajectory is not enough; you also need to communicate and visualize the results to different stakeholders, such as engineers, managers, customers, or regulators. How do you do that effectively? Here are some tips and best practices.

1 Know your audience

The first step is to identify who are the stakeholders and what are their needs and expectations. Different audiences may have different levels of technical background, interest, and involvement in the project. For example, engineers may want to see the detailed parameters, constraints, and trade-offs of the optimization, while managers may want to see the cost, risk, and performance indicators. Customers may want to see the mission outcomes, benefits, and features, while regulators may want to see the compliance, safety, and environmental impacts. Therefore, you need to tailor your communication and visualization to suit each audience and highlight the relevant information.

This is very much inline with the concepts in DARPA‘s Hallmark program (https://www.darpa.mil/news-events/2020-03-27). In this context, a Common ‘Operational’ Picture is a red herring; it is the underlying information flow that needs to be common, consistent and accurate, getting to the right place/people, at the right time, and also get displayed to different stakeholders at the appropriate abstraction levels.

2 Choose the right format

The second step is to choose the appropriate format and medium for your communication and visualization. Depending on the purpose, scope, and audience of your message, you may use different formats, such as reports, presentations, dashboards, or videos. For example, reports may be suitable for documenting the optimization process, methods, and results in detail, while presentations may be suitable for summarizing the main findings, insights, and recommendations in a concise and engaging way. Dashboards may be suitable for displaying real-time or interactive data, charts, and maps, while videos may be suitable for demonstrating the trajectory dynamics, scenarios, and outcomes in a realistic and immersive way.

3 Use clear and consistent language

The third step is to use clear and consistent language to communicate and visualize your optimization results. You should avoid jargon, acronyms, and technical terms that may confuse or alienate your audience, unless you define them or provide context. You should also use consistent terminology, units, and symbols throughout your communication and visualization to avoid ambiguity or inconsistency. You should also use plain and simple language that conveys your message effectively and accurately, without exaggerating or oversimplaining.

'oversimplaining'? A clear indication of the quality of this article, telling us how to suck eggs, so that we can tell grandma how to suck eggs. Other than a complete rewrite, no chance to improve this. It's pretty worthless, spewing AD (artificial dumbness) scraped from irrelevant sources.

4 Use appropriate and appealing visuals

The fourth step is to use appropriate and appealing visuals to communicate and visualize your optimization results. Visuals can help you illustrate complex concepts, show trends and patterns, compare alternatives, and highlight key points. However, you should also be careful not to use visuals that are misleading, cluttered, or irrelevant. You should choose the right type of visual, such as graphs, tables, maps, or animations, that matches your data and message. You should also use colors, shapes, labels, and legends that are easy to see and understand. You should also use visuals that are aesthetically pleasing and consistent with your branding and style.

5 Provide context and interpretation

The fifth step is to provide context and interpretation for your communication and visualization. You should not assume that your audience will automatically understand or appreciate your optimization results. You should provide background information, assumptions, limitations, and references that support your optimization process and methods. You should also provide analysis, explanation, and commentary that highlight the meaning, significance, and implications of your optimization results. You should also provide recommendations, actions, or next steps that follow from your optimization results.

6 Solicit feedback and improvement

The final step is to solicit feedback and improvement for your communication and visualization. You should not consider your communication and visualization as a one-way or final process. You should invite your stakeholders to ask questions, share opinions, or suggest improvements. You should also evaluate the effectiveness and impact of your communication and visualization, using metrics, surveys, or interviews. You should also update and revise your communication and visualization as needed, based on new data, changes, or feedback.
