Celestrak TLE files no longer working for creating satellite scenario

satelliteSimulationDuration = 10; % minutes
startTime = datetime('now','TimeZone','UTC');
stopTime = startTime + minutes(satelliteSimulationDuration);
sampleTime = 1; % seconds
satscene = satelliteScenario(startTime,stopTime,sampleTime);
websave('starlink.tle','https://celestrak.org/NORAD/elements/supplemental/sup-gp.php?FILE=starlink&FORMAT=tle');
tleFile = 'starlink.tle';
constellation = satellite(satscene, tleFile);

Error using satelliteScenario/satellite>throwExceptions
Unable to add satellite to the satelliteScenario.

Error in satelliteScenario/satellite

Caused by:
Error using matlabshared.orbit.internal.generalperturbations.propagate
Unable to calculate position and velocity using SGP4/SDP4 orbit propagator. The mean orbital eccentricity must be either less than 1, greater than or equal to -0.001, or the semimajor axis must be at least 95 percent of the Earth's radius.

This code use to work just fine a couple of weeks ago and now it doesn't. Maybe it has something to do with MATLAB converting Mean Motion from rev/day to rev/sec?

Hey lan,

I reproduced the code from my end in 2024b MATLAB i dont face the isssue and code is working fine.

The below debuging steps may help you:

• Can you clear the workspace and run it.
• Add print statements in between the code.
• Ensure that any required environment variables are set correctly.
• Add breakpoints and check for the root cause.

Refer to the documentation link below for 'satelliteScenario'.

• https://www.mathworks.com/help/aerotbx/ug/satellitescenario.html

Hope it helps!
