Create a Satellite Scenario

Create a satellite scenario with the start time of 02-June-2020 8:23:00 AM UTC and a stop time of five hours later. Set the simulation sample time to60seconds.

startTime = datetime(2020,6,02,8,23,0); stopTime = startTime + hours(5); sampleTime = 60; sc = satelliteScenario(startTime,stopTime,sampleTime);

Add Satellites to the Scenario

Add satellites to the scenario from thethreeSatelliteConstellationTLE file.

sat = satellite(sc,"threeSatelliteConstellation.tle");

Show the satellites in orbit and plot their ground tracks over 20 minutes.

show(sat) groundTrack(sat,"LeadTime",1200);

Return Orbital Elements and Position of the Satellites

Display the orbital elements of each satellite in the scenario.

ele1 = orbitalElements(sat(1))

ele1 =struct with fields:MeanMotion: 9.1649e-04 Eccentricity: 1.0000e-03 Inclination: 55 RightAscensionOfAscendingNode: 175.0000 ArgumentOfPeriapsis: 100 MeanAnomaly: 174.9900 Period: 6.8557e+03 Epoch: 02-Jun-2020 18:43:16 BStar: 1.0000e-04

ele2 = orbitalElements(sat(2))

ele2 =struct with fields:MeanMotion: 8.5025e-04 Eccentricity: 1.0000e-03 Inclination: 55 RightAscensionOfAscendingNode: 350.0000 ArgumentOfPeriapsis: 90 MeanAnomaly: 310.0877 Period: 7.3898e+03 Epoch: 02-Jun-2020 18:33:26 BStar: 1.0000e-04

ele3 = orbitalElements(sat(3))

ele3 =struct with fields:MeanMotion: 8.6605e-04 Eccentricity: 1.0000e-03 Inclination: 55 RightAscensionOfAscendingNode: 270 ArgumentOfPeriapsis: 95 MeanAnomaly: 119.9007 Period: 7.2550e+03 Epoch: 02-Jun-2020 18:37:40 BStar: 1.0000e-04

Return the latitude, longitude, and altitude of the first satellite at time 02-June-2020 12:30:00 PM UTC.

time = datetime(2020,6,02,12,30,0); pos = states(sat(1),time,"CoordinateFrame","geographic")

pos =3×1106×0.0000 -0.0001 1.4212

Add Ground Stations

Add the Madrid and Canberra Deep Space Communications Complexes as the ground stations of interest, and specify their latitudes and longitudes.

name = ["Madrid Deep Space Communications Complex",..."Canberra Deep Space Communications Complex"]; lat = [40.43139, -35.40139]; lon = [-4.24806, 148.98167]; gs = groundStation(sc,"Name",name,"Latitude"拉t,..."Longitude", lon);

Return Azimuth Angle, Elevation Angle, and Range at a Specified Time

Return the azimuth angle, elevation angle and range of the first satellite with respect to the Madrid Deep Space Communications Complex at time 02-June-2020 12:30:00 PM UTC.

time = datetime(2020,6,02,12,30,0); [az,elev,r] = aer(gs(1),sat(1),time)

az = 264.2457

elev = -34.0669

r = 9.3088e+06
