QuaternionRelative attitude of the target in the camera frame, per frame.
Target translationTarget position in the camera frame. tz is the range on the left axis (m); tx/ty use the right axis.
Optical-axis angleAngle from the chaser body front axis to the Sun, the Earth centre and the target — the annotation’s SunToCameraAngle, EarthToCameraAngle and TargetToCameraAngle. A flat 0° target trace means the chaser is pointed at the target.
Scene / illuminationBands along the bottom: eclipse or daylight, plus when the Earth and the Sun are inside the field of view.
TrajectoryCorkscrew approach around a rigid body nadir-pointing target, sun-synchronous LEO. Helix radius 10 m · radial offset 20 m · initial along-track offset 30 m · angular rate 0.001 rad/s · along-track drift rate 0.0016 m/s · initial phase 2.0944 rad. Starts at 2025-09-29T00:00:00 UTC.
