Anyone running a PtP 450 900mhz backhaul on the same tower as 450i or FSK
900mhz equipment? Since the PTP unit does not have GPS I am wondering if
there are issues?
Thanks,
Brandon

It's not quite like shooting a bullet. There is a window that
they can maneuver within. It may have to do with the amount of
propellant carried in the "garage" attached to the back of the
crew dragon. There also has to be enough left in that to de-orbit.
If this was widely deployed, it would impact PMP450 CBRS users, since you would
be competing for the same GAA channels (or they could buy PAL’s I guess).
So in my area, I have the following concerns with CBRS now:
1. Ship based radar
2. Cellular LTE users
3. CBRS based radio sy
If I remember correctly, the ptp450 does support sync over power, but I
think it's somewhat complicated to make ptp and pmp sync with each other. I
imagine you would have problems with two of anything 900mhz on the same
tower if they aren't synced.

Nobody had thought it through.
More throttle == faster == higher orbit == slower orbital period.

Yes on the up and down. But if you want to catch up to another airplane you do
give it more throttle.

Right. But in an airplane throttle also makes you go up.
In fact:
Up/down is basically controlled by throttle
While
Speed is controlled by elevators.
Slow down? Pull up
Speed up? Push down
Go up? Throttle up
Go down? Throttle down

Sn5&6 are already built and ready to incorporate the changes that come out of

Interesting read. Apparently it was a bigger and more complicated screwup than
I remembered. BTW, I don’t think my roommate was involved in developing that
product, more like a legendary example, as you described.
737 Max fiasco seems to belong in somewhat the same category. Design reuse,
I thought docking was fully automated, the humans are essentially cargo.
