− | ''"While we don't know the orbit, we're aiming for a circular low altitude LEO - around 300 km. altitude. That would mean a roughly 90 minute orbit with several daylight passes per day (usually 3 or 4 over any given location). Each pass would be somewhere around 5 minutes long."'' | + | ''"While we don't know the orbit, we're aiming for a circular low altitude LEO - around 300 km. altitude.
