constant change on a map

I have a code that show a satellite around an earth. What I must do to see its move? The position of satellite is changing with time, so think that I need to write a code that (when the script is running) will update my time. I have no idea what I have to do. For time I use simple t=now.

Thanks.

I attach part of a code:

worldmap world;
load coastlines; 
plotm(coastlat, coastlon);
%to plot the map

.... parameters calculated from TLE date (all keplers parameters)

lla = ecef2lla([xk yk zk], 'WGS84');
geoshow(lla(1,1), lla(1,2), 'DisplayType', 'Point', 'Marker', '+', 'Color', 'red');  %show the satellite

From my understanding you want to display a satellite move around a planet overtime here are some reference functions that might help you.
