limit elevation angles for a phased array on a platform/aircraft to satellite
I am able to run and modify this example: Aircraft-to-Satellite Communication for ADS-B Out – MATLAB & Simulink (mathworks.com)
except I do not know how to limit the elevation angles to the satellite such as can be done with a ground station very easily as in the ground station code below:
% Create a satellite scenario with AutoSimulate set to false
sc = satelliteScenario(‘AutoSimulate’, false);
% Define the satellite with a higher orbit
semiMajorAxis = 7000e3; % Semi-major axis in meters (higher orbit)
eccentricity = 0.001; % Eccentricity
inclination = 90; % Inclination in degrees (adjusted for closer pass)
rightAscension = 164.5; % 105 Right ascension of the ascending node in degrees (adjusted for longitude)
argumentOfPeriapsis = 0; % Argument of periapsis in degrees
trueAnomaly = 0; % True anomaly in degrees
sat = satellite(sc, semiMajorAxis, eccentricity, inclination, …
rightAscension, argumentOfPeriapsis, trueAnomaly);
% Set the elevation range
minElevation = 37; % Minimum elevation in degrees
maxElevation = 90; % Maximum elevation in degrees
% Define the ground station (representing the aircraft)
gs = groundStation(sc, ‘Name’, ‘MyAircraft’, ‘Latitude’, 40.0150,…
‘Longitude’, -105.2705, ‘Altitude’, 10000, ‘MinElevationAngle’,minElevation);
It is a built in property of the grounStation function. How can I use the above example, but limit the elevation angles like in the groundStation property?
This is some of the aircraft code:

minElevationAngle = 30; % degrees
aircraft = platform(sc,trajectory, Name="Aircraft", Visual3DModel="airplane.glb");
The limits I want to impose on the simulation and viewing are from elevation = 90 to 30.
