In view from you
Nobody watches GPS IIR-7 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 IIR-7, 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 the Indian Ocean LIVE
Where is GPS IIR-7?
At 4:55:38 PM UTC GPS IIR-7 was over the Indian Ocean (11.6° S, 77.5° E), 21,004 km up, moving at 3.82 km/s and in sunlight.
What is GPS IIR-7?
A navigation satellite in medium Earth orbit, in space since Jan 30, 2001.
Can I see GPS IIR-7?
No, not with the naked eye: no brightness has been published for GPS IIR-7, 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 IIR-7, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to GPS IIR-7 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.
