In view from you

Nobody watches GPS II-4 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-4, 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 II-4?

At 6:21:03 PM UTC GPS II-4 was over the Indian Ocean (45.8° S, 83.5° E), 21,258 km up, moving at 3.8 km/s and in sunlight.

What is GPS II-4?

A navigation satellite in medium Earth orbit, in space since Oct 21, 1989.

Can I see GPS II-4?

No, not with the naked eye: no brightness has been published for GPS II-4, 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-4, so every position here comes from its orbital elements.

In orbit

Close approaches
No close approach to GPS II-4 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.
