#Future Higher "Min elev" for satellite passes #future

Phil Somers
 

Currently 20 degrees is the highest minimum elevation that can be selected for recording passes. A higher minimum elevation would be useful in several situations:

1. Low gain antennas or low sensitivity receivers may require higher minimum elevations.

2. Maybe only "almost overhead" passes might be desired, for example for weather satellites.

3. Maybe only a short bit of telemetry is required occasionally and it could be best done during short, high elevation passes.

4. Maybe storage size is limited and only a small number of high elevation passes can be stored or are desired..

5. Probably a change of "Min elev" would be very easy to implement, and it would have no detrimental effect on users who don't want or need a higher value.

I suggest that the Min elev be increased from the current 20 degrees to 80 degrees. Thanks.

Also, I notice that, even now with 20 degrees set as the minimum elevation for the next pass, the map display shows the next AOS based on the default 10 degrees elevation. The map AOS etc. for the next pass should show the same info as the Automatic Scheduler, based on the same minimum elevation.

Urg,

 

Let me think about the logic here.

….Or maybe it could also check the minimum elevation angle against a user generated horizon table (1 deg intervals)

This could be  great help in ensuring compliance with the radiated power limitations

Que?

 

You’ll have to give me the dumbed-down version of this, I wasn’t aware we had any such limitations. Over-exposing neighbours to RF is all part of the fun here.
