Hello,

I am having problems closing the link between the sat's transmitter and the groundstation's receiver. This is what I have in this part:

gimbalSatTx = gimbal(sat, ...
    "MountingLocation",[0;1;2]);  % meters
satTx = transmitter(gimbalSatTx,...
    "MountingLocation",[0;0;1], ... %meters
    "Frequency", 7900e6, ... %hertz
    "Power",-3.01,...%debibel-watts
    "BitRate",150); %mbps
gaussianAntenna(satTx, ... %default antenna
    "DishDiameter",0.5); % meters
gimbalSvalbard = gimbal(gs(1), ...
    "MountingAngles",[0;180;0], ... % degrees
    "MountingLocation",[0;0;-5]);   % meters
gs_1Rx = receiver(gimbalSvalbard,...
    "Name","GS 1 Receiver", ... 
    "MountingLocation",[0;0;1], ...      % meters
    "GainToNoiseTemperatureRatio",3, ... % decibels/Kelvin
    "RequiredEbNo",1);                   % decibels);
gaussianAntenna(gs_1Rx, ...
    "DishDiameter",3.7); % meters
pointAt(gimbalSatTx,gs(1)); 
               
lnk = link(satTx,gs_1Rx);
linkIntervals(lnk)
