Model satellites in orbit, analyze access between the satellites and the ground stations, and visualize the fields of view and ground tracks of the satellites. Orbit Propagation Methods Analyze the motion and dynamics of aerospace vehicles with short-period requirements, boundary line, and altitude co...
Add a platform to the satellite scenario based on the trajectory. pltf = platform(sc,trajectory) pltf = Platform with properties: Name: Platform 1 ID: 1 ConicalSensors: [1x0 matlabshared.satellitescenario.ConicalSensor] Gimbals: [1x0 matlabshared.satellitescenario.Gimbal] Transmitters: [1x0...
This MATLAB function adds Satellite objects from file to the satellite scenario specified by scenario.
Add the Satellite From the Loaded Trajectory Add the observation satellite to the scenario. Get sat = satellite(scenario, mission.Data.PositionTimeTableGCRF, ... "CoordinateFrame", "inertial", "Name", "ObservationSat"); Add a conical sensor to the satellite, with a 35 deg half angle to...
trajectory = geoTrajectory([40.6413,-73.7781,10600;32.3634,-64.7053,10600],[0,2*3600],AutoPitch=true,AutoBank=true); pltf = platform(sc,trajectory); Determine the azimuth angle, elevation angle, and range of the platform with respect to the satellite at April 25, 2023, 1:26 AM UTC. ...
Furthermore, we simulated the system with Matlab program under different bandwidth. The results demonstrate that the proposed position control system achieves a good control performance. The simulation indicates that PUD controller performed well on the satellite relative-trajectory simulation.Jianfeng Sun...

Firstly, two cascaded Tracking Differentiators are used to arrange the transition process of the attitude command, which not only reduces overshoot and oscillation of the tracking process, but also obtains the angular acceleration information of attitude trajectory for feed-forward compensation. Secondly,...
Next, we might like to plot the orbit path. This can be done via thePoint Trajectoriesplot type, which lets us enter trajectory data and the position of the spacecraft over time, and plot a line along its path. In addition, theAnnotationplot type lets us evaluate and plot expressions tha...
Flight path B would have been used for spacecraft intended to go into orbit with an inclination of 45 to 65 degrees, with a trajectory going over a very deserted area of the Australian mainland. A third trajectory, Flight path C, was intended for sun-synchronous orbit injections as well ...
