@BlueCoder's nice answer to Syncom-3 was the first geostationary satellite. Anyone know of a description of the onboard electronics? mentions that the the master oscillator was doubled eight times to ...

I am interested in any description of the electronics on Syncom-3, the first geostationary satellite. I've been able to find quite a bit of general information. There was a pair of 2 Watt TWTs and ...

The positions of satellites in geostationary orbits can be characterized by their longitude, the longitude of a point on Earth's equator that is nadir to the spacecraft. Satellites in GEO will ...

If I had the material that had the tensile strength, would it be possible to have it dangle from the lowest most practically possible geostationary object down into the atmosphere? Would it not ...

I envision a conductive wire that is extruded out of a satellite as it completes it orbit, and then goes past it's start point a bit before stopping the extrusion. Then the satellite is sent to grab ...

Sun outages occur when a satellite, usually one in a geostationary orbit, passes between a ground station and the sun. Seen from the point of view of the ground station, the sun looks like it passes ...

I am currently looking into the possibility of very tiny automated drone transportation. I hope to prove viability by testing using orbital mechanics experiments. Achieving geostationary orbit and ...

edit: It's been seven months now, have any of the 'gift' transponders been used or at least tested yet by the gift recipient nation? The BBC news item India launches 'invaluable' South Asia satellite ...

I understand that all satellites must have burn corrections to keep their orbits where they are needed. However my question is specifically about what those changes are in magnitude from the desired ...

As we know, something released from around 36000 km height from a space elevator will remain in geostationary orbit around the Earth. Things released from lower will go into an elliptical orbit ...

Building off of this previous question, is there a more detailed summary anywhere of the process that a commercial satellite would have to go through to obtain a GEO slot? The documentation I have ...

I was wondering if, and how, one can tell from the values in a TLE whether an orbit is LEO, MEO, HEO, or GEO. I'd like to do this in code eventually, so any formulas or threshold values would be much ...

Now that the protests at Kourou Space Center in French Guiana are over, Arianne has launched both EutelSat 172B and ViaSat-2 as 2017-029A. While EutelSat 172B has a ...

This question is a bit of a mix between satellite knowledge and math. Suppose I have the "look angles" (elevation and azimuth) for an otherwise unidentified geostationary satellite, and I would like ...

There is one mission by GSFC/NASA - Shields-1 to be launched into GTO. Apart from that I couldn't find any other mission to GTO/GEO. It would be of great help if there is any information on this.

A launcher upper stage may not stay in orbit for long, as it does not need to go as high as the payload and thus travel at an altitude at which although it is thin, the atmosphere is still dense ...

Earth's geostationary orbit has many human-made satellites which have helped vastly with communications and research. Aside from this artificial collection, are there any other objects orbiting a ...

The previous question How much time does it take to circularize a GTO orbit using ion propulsion? has a good, quantitative answer based on a known delta-v. But I'm wondering how would you actually ...

My assumption is that any body in the solar system would have it's own specific geo-synchronous orbit height. But when I took a look at Phobos and calculated the GEO height based on the simple formula ...

This post got me thinking about something I've never quite been able to picture about geostationary orbit. In a perfect model of a spherical earth, there is an infinitesimal circle in the plane of the ...

That seems a bit counter-intuitive, because in an orbit above the belt, the satellite would eventually lose gain velocity, so its orbit would intersect the orbital plane of the geostationary ...

When a satellite is in geostationary orbit, it is supposed to stay above one spot of the earth and rotate around the earth at the same rate the earth spins. But how exact does that equality need to be?...

I am wondering to know if it's possible to stand still (no movement at all with respect to the Sun) in space. Can it be possible? I am thinking that when we move upwards from Earth's surface an ...

I've read this already and some Wikipedia articles, but found no real estimates on how much does a satellite deviate from its standard location. Say that the standard sub-satellite point (SSP) is <...

Imagine I'm sitting on a geostationary satellite. I can see the Earth in front of me. It's about the size of a soccer ball at arm's length. To the left and right, I can see similar satellites in the ...

I was speculating that geostationary satellites could be around possibly for billions of years (i.e. much beyond the point where plate tectonics would have erased all traces of human civilization on ...

Im building a rocket simulation engine and I would like to try and calculate the components of acceleration required to get the rocket into geostationary orbit. For example, the yellow and green lines ...

This answer introduced me to the word Areostationary Orbit - (hint, comes from Ares), an orbit that would remain stationary above a point on the equator of Mars. The article mentions that ...

How is inclination change performed for satellites inserted into GEO? With most launches performed from spaceports at various high latitudes, it's impossible to launch directly into equatorial ...

I've been reading a few things about NOAA's GOES-R satellite, and I noticed this on the GOES-R site: ...will be placed in the 89.5° checkout orbit where it will undergo an extended checkout and ...

This article, this article, and this earlier question indicate that, given enough satellites in LEO, it's possible to substitute between GEO and LEO. The first article and the question have some ...

It is very easy to spot LEO satellites during dusk or dawn. I am wondering if satellites further out in a geosynchronous orbit are also visible. Of course, if even possible, these would appear more ...

How can I know the remaining life of a satellite? I have been using satbeam, and try to calculate it based on launch date + expected life, but it seems to have some problems. For example, for this ...

It's possible/likely that one day we'll be able to post/mail/deliver stuff to a non-terrestrial vehicle, such as an orbiting vehicle or an extraterrestrialLy landed vehicle, without involving the ...

I thought only launches to rendezvous (resupply, repair, space station expansion etc) and direct launches into interplanetary trajectory require precisely timed launch window. Then I read: Geosync ...

A tiny model rocket can't get up very high. Massive rockets can make it to GEO. There must be some theoretical mass threshold where the rocket is "big enough" to make it to GEO - what is that mass? ...

What launch vehicle, spacecraft and target orbit parameters decide the time of launch to GTO for satellites destined for GEO? The target orbital slot is always in the same relative position to the ...

How rapid do the attractive properties of GEO and lagrange points deteriorate with the distance from optimum? How "large" are such locations? At what distance would station keeping require, say, twice ...

One of the biggest issues that I've heard of in building a space elevator is the high tensile strength of the cord used to tether the the elevator to the ground. If there's a structure that's at ...

From what I understand, an object has to keep moving in an orbit to not come crashing down to Earth. (The ISS is the first thing I think of for this.) How then, do satellites which are purpose built ...

After reaching a peak altitude of 222 km the Ariane 5 launcher with Intelsat 29e starts to lose altitude. What is the reason for this trajectory? Youtube video Paper on Ariane 5

I am familiar with all different orbits but I struggle with the new launch injection method in GTO. What are the differences between sub-synchronous and super-synchronous transfer orbits compared to ...

DARPA has proposed orbital maintenance and salvage robots. I had gathered a list of links that was lost when DARPA rearranged their website. But I was able to find this page: Phoenix Makes Strides in ...
