Student path
- Choose a mission scenario (imaging, antenna contact, or solar charging).
- Set the target angle and drag the current angle slider to simulate pointing error.
- Read the verdict and the pointing tolerance for your scenario.
- Copy/export your evidence — local-only, teaching model, not real spacecraft ADCS.
Learning outcomes
Student can explain why attitude control is needed and what pointing error means.
- Explain what attitude control means for a satellite.
- Define pointing error as the difference between target and actual angle.
- State one consequence of large pointing error for a mission.
Concept primer
Understand why a satellite must point in the right direction and what happens if pointing fails.
Open the one-axis simulator; observe target angle vs actual angle before any control is applied.
Sketch a satellite pointing at a ground target; label target, actual, and error directions.

Pointing requirement lab
Why does this spacecraft need to point correctly?
15°
Pointing target: nadir (Earth centre)
Tolerance: ±1°
Outside tolerance — mission objective at risk
Consequence: Image blurred or off-target if pointing error exceeds tolerance.
Key concept
Orbit describes the spacecraft's path around Earth. Attitude describes which direction it is pointing. A perfectly good orbit with wrong attitude still fails the mission.

Assessment (practice only)
Use this as a self-check and discussion starter. It is local-only and not a grade.
Optional: attaches a local summary (completed / quick checks / checklist count).
Quick check
Multiple choice self-check
This is a local self-check to support discussion. It is not a grade.
Quick check: What is the main difference between attitude and orbit?
Quick check: If a CubeSat camera is pointed 30° away from its target, what most likely happens?
Discussion prompt
Short answer (local only)
Write notes for yourself or your group. Nothing is submitted.
Reflection: Name one mission function (imaging, comms, or power) and explain in one sentence why correct pointing is critical for it.

Pointing target: nadir (Earth centre). Tolerance: ±1°.

Evidence capture
Expected outputs learners should be able to show after the lab (Phase 9 evidence engine preview available).
- Live chart: target vs actual angle
- Student names mission harm from large pointing error (comms, power, science)
Reflection
Hold a torch and try to keep the beam on a target while moving — relate to satellite pointing.
Responses are not persisted in this preview unless a specific activity component adds storage later.
Assessment / quick check
Name two mission functions that fail or degrade if pointing error stays large for minutes.
Teacher notes
Tie beam-on-target demo to antenna gain, camera framing, and solar wing illumination.
Teacher use
Anchor on attitude ≠ altitude. A perfect orbit with wrong attitude still fails the mission. Use the three scenarios to show imaging (tight tolerance), antenna contact (moderate), and solar panel charging (relaxed) — each demands different pointing accuracy.
