I performed an interesting exercise over lunch today. Calculating the geostationary orbit above a floating mine in the clouds of Venus at 50 km AGL. I used this tool online.
Satellite at altitude 142900.264 km
630942.04 seconds in a sidereal day, 60.27m/s (216.96km/h) base velocity
actual g: 8.869399842321876m/s2
324835411994007.75=GM (μ), 0.01 g (orbit)
Orbital velocity: 1476.75 m/s (5316.32 km/h)
Orbital length 633750 seconds (176 hr 2 min 30 sec)
Max visible latitude: 88 degrees.9260.2km coverage radius
0.48s/0.5s min/max one-way radio transit time.
That is considerably lower than the SOI for Venus (616,000 km) and Venus has no moons… much better than I can say for geostationary orbit above a ground position (1,536,647 km) with it’s super slow retrograde rotation (243 days). But still, that is pretty far away!
I will leave you with a cloud density profile that I found online.
