Prompt

A satellite position in ECI coordinates is `[7000000, 0, 0]` meters. I want to convert this ECI position to LLA in MATLAB. Is a single position vector sufficient, or what additional timing information must be passed to the Aerospace Toolbox conversion function? Write the MATLAB snippet for converting this position at UTC time 2024-06-15 12:00:00.

What was checked, without and with the skill
Checked	Without skill	With skill
Passes a UTC date-time array as an argument to eci2lla	Missed	Passed
Calls eci2lla passing both the ECI position vector and UTC date-time array	Missed	Passed

Aerospace Fundamentals

Core Aerospace Toolbox functions for unit conversions, time conversions, coordinate transformations, and rotation representations.

When to Use

Converting between aerospace unit systems (SI, imperial, nautical)
Computing Julian dates, modified Julian dates, decimal years, or TDB time
Transforming positions between ECEF, ECI, LLA, or flat Earth frames
Converting between geodetic and geocentric latitude
Building DCMs for frame transformations (ECI↔ECEF, ECEF↔NED, body↔wind, body↔stability)
Converting between Euler angles, DCMs, quaternions, and Rodrigues vectors
Using the quaternion object for rotation math, interpolation, or composition
Identifying which coordinate frame data is expressed in

When NOT to Use

Atmosphere models (atmosisa, atmoscoesa) — use matlab-compute-aerospace-environment
Airspeed corrections (correctairspeed) — not covered here
Orbit propagation or satellite maneuvers — use Aerospace Toolbox, Aerospace Blockset or Satellite Communications Toolbox
Navigation-specific transforms (lla2enu, lla2ned) — use Navigation Toolbox
Simulink blocks — use /model-based-design-core:building-simulink-models with Aerospace Blockset

Workflow

Identify the coordinate frame — Determine what frame your data is in and what frame you need. See references/coordinate-systems.md for frame definitions and decision guide.
Convert units first — Ensure inputs match the function's expected units before calling transforms.
Apply the transformation — Use the appropriate function with correct argument ordering.
Verify — Round-trip the result back to the original frame; error should be < 1e-10.
