Current orbit

Where OPS 0757 is on the world map, with the orbit it is flying
View on live map

One orbit takes a day, as long as the Earth takes to turn, so OPS 0757 keeps above 78.2° E of the equator and never crosses the sky.

Past trackNext orbits

It never rises or sets

OPS 0757 turns with the Earth, standing over one longitude of the equator. From anywhere it can be seen at all it is up day and night, in the same direction, so there is no pass to wait for.

No brightness has been published for OPS 0757, 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 wait for: it never crosses the sky. From the half of the Earth it stands over it keeps the same point day and night, and from the other half it never rises at all.

Summary

Over the Indian Ocean LIVE

Where is OPS 0757?

At 5:39:20 PM UTC OPS 0757 was over the Indian Ocean (2.1° S, 78.2° E), 35,811 km up, standing over one longitude of the equator and in sunlight.

What is OPS 0757?

A communications satellite in geostationary orbit, in space since Feb 9, 1969.

Can I see OPS 0757?

No, not with the naked eye, and it never crosses the sky: OPS 0757 stands over 78.2° E of the equator; the dishes and receivers on the ground use its signals instead.

No operator publishes an ephemeris for OPS 0757, so every position here comes from its orbital elements.

In orbit

Close approaches
No close approach to OPS 0757 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.
