How to simulate a inter satellite link in Iridium Constellation?

Hi.

I generate the Iridium Constellation as suggested here https://it.mathworks.com/help/satcom/ug/coverage-maps-for-satellite-constellation.html. Thanks to the access and acceIntervals functions, I can determine which satellites are in view of my gorund station, located in New York, in the given time interval.

I would also like to simulate the intersatellite links between the satellites that are in view and which are simultaneously also in view from my gorund station. How is it possible to do this?

Once I have the intersatellite links, I can use the aer function not only to get the distance from the ground station to each satellite, but also between the intersatellite links.

Thanks

Hi,

To simulate the intersatellite links between the satellites that are in view of your ground station and which are simultaneously also in view from your ground station, you can follow these steps:

1. Determine the satellites in view of the ground station: Use the "access" and "accessIntervals" functions to determine which satellites are in view of your ground station located in New York during the specified time interval.
2. Identify simultaneous satellite visibility: Filter the satellites that are visible simultaneously from your ground station.
3. Simulate intersatellite links: For each pair of satellites that are simultaneously visible, calculate the intersatellite link distances using the "aer" function.

Hope it helps.
