Every spacecraft operation has a specific communication protocol that defines the rules, procedures, and formats for exchanging information. You should familiarize yourself with the protocol before the operation and follow it strictly during the communication. The protocol may include the use of standard phrases, acronyms, codes, and formats to ensure clarity, consistency, and brevity. For example, you may use the phonetic alphabet to spell out words, or the 24-hour clock to indicate time. You should also know the call signs, frequencies, and channels for your spacecraft and the ground control team.
Understanding and adhering to the communication protocol is critical for spacecraft operations. Familiarize yourself with standard phrases, acronyms, codes, and formats for clear and concise information exchange. Use the phonetic alphabet for spelling, and the 24-hour clock for time. Ensure you know the call signs, frequencies, and channels for both your spacecraft and ground control. Strictly following these protocols enhances clarity, reduces errors, and ensures smooth and effective communication during missions, ultimately contributing to mission success and safety.
When you communicate with the ground control team and other spacecraft operators, you should aim to be clear and concise. Avoid using jargon, slang, or ambiguous terms that may confuse or mislead your listeners. Use simple and direct language that conveys your message effectively. State your purpose, intention, or request clearly and briefly. Repeat or confirm important information to ensure accuracy and understanding. For example, you may say "Requesting permission to execute maneuver X. Over." or "Confirming telemetry data received. Over."
Communication is a two-way process that requires listening and acknowledging. You should pay attention to the messages you receive from the ground control team and other spacecraft operators, and acknowledge them promptly and appropriately. You should also ask questions or clarify doubts if you are unsure or unclear about something. Listening and acknowledging can help you avoid misunderstandings, errors, or conflicts that may jeopardize your operation. For example, you may say "Roger that." or "Copy that." to acknowledge a message, or "Please repeat." or "Can you clarify?" to request more information.
One of the challenges of communicating in space is dealing with delays and disruptions. Depending on the distance and the medium of communication, there may be a significant time lag between sending and receiving a message. There may also be noise, interference, or signal loss that can affect the quality and reliability of the communication. You should be aware of these factors and manage them accordingly. You should plan ahead and anticipate possible delays and disruptions. You should also use techniques such as buffering, redundancy, or encryption to enhance your communication. For example, you may add a pause or a filler word before or after a message to account for the delay, or repeat or rephrase a message to overcome the noise.
Communicate early, and communicate often. Assume worst-case scenarios, and you won't be caught off-guard, should they arise. You will never always have ideal circumstances.
Communication is not a static or fixed process, but a dynamic and flexible one. You should be able to adapt to different situations and feedback during your spacecraft operation. You should monitor the status and progress of your operation and adjust your communication accordingly. You should also respond to the feedback and requests from the ground control team and other spacecraft operators. You should be prepared to change your plans, actions, or messages if needed. For example, you may increase or decrease the frequency or length of your communication depending on the situation, or follow or modify a command or instruction based on the feedback.
Communication is not only about exchanging information, but also about building and maintaining relationships. You should communicate with the ground control team and other spacecraft operators with professionalism and courtesy. You should respect their roles, responsibilities, and opinions. You should also express your appreciation, gratitude, or support when appropriate. You should avoid using rude, offensive, or inappropriate language or tone that may damage your rapport or reputation. For example, you may say "Thank you for your assistance." or "Good job." to show your respect or recognition, or "I apologize for the inconvenience." or "I appreciate your patience." to show your humility or empathy.
Shouting. Full-on Gordon Ramsey. Maximum SnR for your voice. Saturate the receivers. Close the link budget between your vocal chords and the team's ears, then add on a safety margin of 80dB more. This may or may not actually be terrible advice.
Cross-training enhances the understanding & communication between ground control & spacecraft operators. In an Earth observation mission, we organised cross-training sessions where spacecraft operators spent time in the ground control centre and vice versa. This exposure helped both teams understand each other’s challenges & workflows. Documenting the training sessions & the insights gained fostered a better collaborative environment & improved overall communication. Ensuring the security of communication channels is crucial to prevent unauthorised access & data breaches. In a military satellite project, we employed encrypted communication channels using AES-256 encryption for data transmission between the spacecraft and ground control.
