In view from you
Nobody watches NNS 30100 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 NNS 30100, 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 Antarctica LIVE
Where is NNS 30100?
At 6:20:03 PM UTC NNS 30100 was over Antarctica (78.5° S, 80.3° E), 1,068 km up, moving at 7.33 km/s and in sunlight.
What is NNS 30100?
A navigation satellite in low Earth orbit, in space since Aug 18, 1966.
Can I see NNS 30100?
No, not with the naked eye: no brightness has been published for NNS 30100, 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 NNS 30100, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to NNS 30100 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
NNS 30100 shares its launch, 1966-076, with 3 other bodies the catalogue lists in orbit.
| Body | What it is |
|---|---|
| SCOUT A R/B | Rocket body |
| SCOUT A DEB | Debris |
| SCOUT A DEB | Debris |
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.
