Oh wow, that would pretty limiting. Thank you for that heads up!

I see that from the 400 miles altitude they filed with the FCC, you'd expect them to be able to provide maybe an extra 2 hours before + after sunrise/sunset near the equator. However, that appears to improve to almost 4 hours at 50 degrees latitude - assuming 30 degrees of elevation is sufficient for the light to not get too scattered through the atmosphere. If you assume a much more conservative 60 degree elevation requirement then it would be 3 hours before+after sunrise/sunset at 50 degrees latitude.

It also depends on the season, but this has a much smaller effect than latitude.

Shortening the night by a combined 6-8 hours might be quite useful for operations in Ukraine which occur near 50 degrees latitude.

That's really not correct, simply based on where their satellites will be and the orbits they must follow. Do you work there or something? The whole thing is an obvious scam. None of what you say is realistically possible in practice.
