Chris or others

How does the Gonets satellite fit in the Glonass system. They operate in different orbits and perform different functions. At least thats what I understood from Gunters page on Strela and Gonets?

How are these two projects intertwined?

They aren't!

The report mixed Gonets-M with GLONASS-M, but these systems are completly different. Gonets-M is a low earth orbit store-dump communication system, while GLONASS is a intermediate orbit navigation system.

So Gonets-M has no relation to GLONASS, despite all the Russian reports saying it is, and none of our Russian friends on here correcting it? :o

What the heck, even Rosmoskos has "the Gonets-M satellite is intended to provide digital user terminal GLONASS positioning data, as well as electronic mail services"

Changing the article, but that's absolutely unbelievable and very unprofessional of them when you can't even trust the Russian Space Agency's own site. Thanks Gunter!

The Roskosmos page is just a "here's what other news services are saying about us" page, although they don't make that very clear.
The only official statement I can see is
http://www.roscosmos.ru/main.php?id=2&nid=10288
from Khrunichev PAO, which doesn't say anything about the payload.

I did wonder if Gonets might have some kind of Glonass *receiver* on board that could be used as an augmentation system of some kind... but we certainly haven't heard of this before. Gunter's assumption that Novosti has just stuffed it up completely is also plausible.

OK, now I see http://www.khrunichev.ru/main.php?id=1&nid=1797  - a press release from the launch service provider Khrunichev which makes the statement about the user terminals getting GLONASS data. Now Khrunichev don't make the payload, but I would not expect them to get this wrong (I would actually trust them more than Roskosmos in fact). I think this is the source of the other (Novosti-RIAN news agency) story. So I'm back to leaning on the idea that Gonets-M has some kind of payload that augments Glonass in some way. Russian friends? Hello?

Thanks for looking into that. As soon as I saw Gunter's comment, I wiped all reference to GLONASS out of the article. Best action considering!

The other possibility is that it's like Orbcomm. You can imagine that if you have a Glonass receiver on your lorry, which sends an encoded message to a dedicated transponder on Gonets, Gonets then relays that Glonass data (saying where your lorry is) back to headquarters, at the cost of very very few bytes (so cheap).

Or, with a Glonass receiver on each Gonets, the *Gonets* satellites can know where *they* are and (with degraded accuracy) send out a Glonass-compatible signal, this is the 'augmentation'  idea.

If the Russian's have not in fact done either of these things with Gonets, they should, and I'd like 5 percent of the gross please.

Any idea of serial numbers of launcher and upper stage ?

Do you know the official designation of Gonets-M satellites ?

There is apparently some kind of relationship between Gonets-D1 and GLONASS. My Russian isn't good enough - so here only a machine translation from http://www.gonets.ru/?page=4

Determination of coordinates
Subscribers are offered a way to define your own geographic coordinates for the signals of the GPS / «Glonass». When incorporated into a subscriber terminal board GPS-receiver provides accuracy up to 100 meters.

According to http://www.rosles-re.ru/files/file/100910_Gonets_Launch.pdf, two Kosmos satellites are Strela-3 and Rodnik satellites.

Well done anik !
Last enigma : which one is Strela-3, and which one is Rodnik ?
