accessPercentage

Percentage of time when access exists between first and last node defining the access analysis

    Description

    example

    acpercent = accessPercentage(ac) returns the percentages of time from start time to stop time of the satellite scenario when access exists between the first and last node of each access object in the input vector.

    Examples

    collapse all

    Create a satellite scenario object.

    startTime = datetime(2020,5,1,11,36,0);
    stopTime = startTime + days(1);
    sampleTime = 60;
    sc = satelliteScenario(startTime,stopTime,sampleTime);

    Add a ground station to the scenario.

    gs = groundStation(sc);

    Add satellites to the scenario.

    semiMajorAxis = [10000000 10000000];                  % meters
    eccentricity = [0 0];
    inclination = [0 30];                                 % degrees
    rightAscensionOfAscendingNode = [0 0];                % degrees
    argumentOfPeriapsis = [0 0];                          % degrees
    trueAnomaly = [0 10];                                 % degrees
    sat = satellite(sc,semiMajorAxis,eccentricity, ...
          inclination,rightAscensionOfAscendingNode, ...
          argumentOfPeriapsis,trueAnomaly);

    Add access analysis between the ground station and each satellite.

    access(gs,sat(1));
    access(gs,sat(2));

    Obtain the access percentage between the ground station and each satellite.

    ac = gs.Accesses;
    acPercent = accessPercentage(ac)
    acPercent = 2×1
    
       15.0000
       14.9306
    
    

    Input Arguments

    collapse all

    Access analysis, specified as a row vector of a Access objects.

    Outputs Arguments

    collapse all

    Access percentage, returned as a row vector of nonnegative numbers.

    Note

    When AutoSimulate of the satellite scenario is true, the percentage corresponds to the duration between StartTime and StopTime. When it is false, the percentage corresponds to the duration between StartTime and SimulationTime.
