In view from you
Nobody watches GPS II-9 go over, but a receiver still asks whether it is above the horizon. Say where you are and this card answers.
Your position is rounded to about a kilometre and sent only to the Orbinauts API, to find the pass.
No brightness has been published for GPS II-9, so it is not a naked-eye satellite and no city page carries pass times for it. Nothing here estimates one.
Seeing it
There is nothing to go outside for: it is far too high and too faint for the naked eye. What you notice of it is a position fix, and the card above says whether it is above your horizon to give you one.

Summary
Over Tanzania LIVE
Where is GPS II-9?
At 6:20:47 PM UTC GPS II-9 was over Tanzania (9.4° S, 35.6° E), 21,344 km up, moving at 3.79 km/s and in sunlight.
What is GPS II-9?
A navigation satellite in medium Earth orbit, in space since Oct 1, 1990.
Can I see GPS II-9?
No, not with the naked eye: no brightness has been published for GPS II-9, and nothing here estimates one; receivers on the ground use its signals instead, whenever it is above their horizon.

No operator publishes an ephemeris for GPS II-9, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to GPS II-9 has been reported publicly in the past thirty days.
From Space-Track’s public conjunction messages; the latest report was issued Nov 8, 2026, 1:11 PM, 3 hours old. Only approaches serious enough to be reported publicly are listed: within three days and, for two bodies near the Earth, closer than a kilometre with a chance of a collision above 1 in 10,000, the level at which NASA moves the ISS.
