Does satellite.js provide a way to determine if a satellite is above a ground station?

I'm trying to predict when a satellite will cross some coordinates, is there a way to know if it's visible from said coordinates?

Thanks,
Lachlan

Yes! See the readme, basically the ground station coordinates is the "observer". You'd be most interested in computing the "look angles" - azimuth is the compass direction of the satellite from the perspective of the ground station (observer) and elevation is degrees above the horizon (90 degrees is overhead). Note that elevation above 0 degrees doesn't guarantee that the ground station can connect to the satellite - e.g. mountains or trees on the horizon which obstruct.
