In view from you
Nobody watches GPS IIA-8 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 IIA-8, 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 Pacific Ocean LIVE
Where is GPS IIA-8?
At 6:21:37 PM UTC GPS IIA-8 was over the Pacific Ocean (3.6° S, 157.5° E), 21,315 km up, moving at 3.8 km/s and in sunlight.
What is GPS IIA-8?
A navigation satellite in medium Earth orbit, in space since Dec 18, 1992.
Can I see GPS IIA-8?
No, not with the naked eye: no brightness has been published for GPS IIA-8, 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 IIA-8, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to GPS IIA-8 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.
Launched with
GPS IIA-8 shares its launch, 1992-089, with one other body the catalogue lists in orbit.
| Body | What it is |
|---|---|
| DELTA 2 R/B(1) | Rocket body |
Read from the international designators of the US catalogue: the year and the launch number every piece of one launch shares. A body that has come down is no longer listed.
