In view from you
Nobody watches Insat 1B 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 Insat 1B, 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 too faint for the naked eye. What reaches you from it reaches a dish or an antenna, not an eye.

Summary
Over the Democratic Republic of the Congo LIVE
Where is Insat 1B?
At 5:39:34 PM UTC Insat 1B was over the Democratic Republic of the Congo (1.8° N, 22.7° E), 35,819 km up, moving at 3.07 km/s and in sunlight.
What is Insat 1B?
A communications satellite in an inclined geosynchronous orbit, in space since Aug 30, 1983.
Can I see Insat 1B?
No, not with the naked eye: no brightness has been published for Insat 1B, and nothing here estimates one; the dishes and receivers on the ground use its signals instead.

No operator publishes an ephemeris for Insat 1B, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to Insat 1B 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
Insat 1B shares its launch, 1983-089, with one other body the catalogue lists in orbit.
| Body | What it is |
|---|---|
| INSAT 1B R/B(PAM-D) | 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.
