Eutelsat Hot Bird 13F & 13G

[Europesat]

For sure something serious happened , i observed that it didn't complete the test rather than heading east it went west ...let's wait for Eutelsat statement soon

 

[mianabid]

It's back now

Moving east

What a load af tosh!

Well adjusted 45/60cm dishes are absolutely fine for Sky UK/Freesat here in the UK. Yes you might lose reception in an extreme downpour but seeing as thats only going to happen once or twice a year for a few minutes. And wet snow in the winter sitting on the lnb arm might take signals out but thats only going to happen every couple of years, and a larger dish isnt going to helpb as the attenuation is extreme in wet snow..

Yes you need bigger dishes in tropical areas where there is heavy rainfall every day to compensate for the attenuation but thats part of living in such areas...

Can definitely vouch for this. The UK & Ireland spot beams on the Astra 2E/F/G satellites are ridiculously strong. Maybe a touch less stronger than the old DBS birds of the early 90's , but within the planned service area of the beam they are by far the most powerful Ku-Band signals in the Clarke Belt in my experience. Eutelsat have published the footprints of the 2E & 2F satellites that show more detail than Astra's own published footptint, and they show a 58 dbW contour essentially covering the whole of the UK & Ireland except for the Shetland Isles & maybe the extreme SW corners of Co. Kerry - I'd guess that the centre of the beam (in around the Isle of Man) is hitting >60 dbW. Even the European beams on these satellites are pretty powerful, albeit less than the spot beams, even the wide European beam on Astra 2G. I've no issues with reception on a 45cm dish here in Co. Tyrone for all services from 28E, even those on the 2G European beam. At worst, you might lose reception of the weakest signals no more than a handful of times per year due to heavy rain, and the strongest once or twice a year. There are exceptional circumstances that can happen, a few years back I had my motorised 120cm dish trained on 28E during a thunderous rainstorm and everything was lost, even that size of a dish couldn't win in that battle. Nonetheless, a properly installed 45cm dish or a Sky Zone 1 dish (the mk4 version is roughly equivalent to a 50cm standard offset dish in my calculations) will easily give service from 28E in the UK & Ireland in over 99% of locations for >99.9% of the time.

However, this can take into account the general climate of the areas being served. The temperate climate of the British & Irish Isles sees plenty of rain, but rarely sees vast amounts fall in a very short period of time, so rain fade conditions should be calculated to take this into account. In my experience, if your SNR reception of a transponder is at least 3db higher than the minimum needed in dry conditions, you should be fine in all but the most torrential rain in this part of the world for Ku-Band reception in most cases.

What about strong winds? That is a factor too.

In windy conditions, smaller dishes actually have two advantages over larger dishes - (1) they have a lower wind load, meaning that they are less likely to temporarily deform from their parabolic shape when facing strong winds, as well as putting less stress on any mounts they are on - particularly so when the dish is mounted on a pole above a bracket usually affixed to a wall and thus subject to some wobble. (2) Smaller dishes have a wider 3db beamwidth compared to larger dishes. This not only makes them a little easier to initially align (assuming a lack of interference from nearby birds), but also allows a little more "give" to be had if such a dish is temporarily put out of alignment being on a shaky pole. A similar principle applies to dishes on ships that are designed to receive from geostationary satellites - these dishes are affixed to a stabilisation system that continiously adjusts from the movement of the ship as it travels to ensure that the dish remains pointed to a particular spot in the sky. However, they are not absolutely perfect and a little amount of legroom is desirable to ensure that during certain periods of heavy seas where the pitch & roll of the ship can vary a lot, reaction times from the stabiliser are good enough so that reception from the wanted satellite(s) is not lost. In this sense it is best to use the smallest dish practical, usually at a similar size to domestic installations on dry land assuming an equal dbW value..

Eutelsat HotBird 13F in orbital test mode

March 28, 2023

By Chris Forrester

Eutelsat’s important HotBird 13F satellite, launched back in October 2022, is now in orbit. It has taken the past few months since its SpaceX launch to steadily raise its orbital height using its on-board electrical propulsion. Prime contractor for the satellite was Airbus and Eutelsat is using the Airbus/ESA Eurostar Neo platform.

Currently HotBird 13F is being tested and is expected to come into service during Q2 of this year.

But 13F is not alone. It has a sister satellite, HotBird 13G, which was launched on November 3rd 2022 and will eventually be collocated with 13F at the HotBird orbital position of 13 degrees East. These two satellites will replace three existing Eutelsat craft (13B, 13C and 13E, which will then be free to be moved to other locations).

The pair will also extend Eutelsat’s overall footprint and their on-board – and much improved technology – will mean the new satellites are much more resilient as far as signal jamming is concerned.

The two have improved footprints which will extend over the whole of Europe and the Middle East, and parts of Africa and Asia.

The satellite actually is at 0.45°E orbital posital and is in test phase

 

[Europesat]

Kindly someone update Tle for this bird it's should be close 13e ???

 

[solly]

i think 13f waiting the position after hotbird 13g final test

 

[Europesat]

Hotbird 13f info

 

[mianabid]

Any tests going on or the testing activity completed

It's around.50 East as per tracking website

 

[solly]

It look mid May start move

 

[solly]

eutelsat 10b it look same location like hotbird 13f
any check curect position

 

[Mustafaiq1998x]

Anything new about the position or when it will move to 13 E° ?

ESTIMATED ENTRY INTO SERVICE: Q2/Q3 2023

Future Eutelsat Satellite Launches | Eutelsat ​

Eutelsat is launching five new satellites in the next three years: KONNECT VHTS, HOTBIRD 13F & 13G, EUTELSAT 10B and EUTELSAT 36D

Eutelsat's Hot Bird 13F and Hot Bird 13G satellites will begin commercial service at 13° East in two phases. The first will take place at the end of May 2023 , and the second is expected at the end of July 2023 . During this period, services will be transferred gradually, in close cooperation with our customers.

Today the ITU released the ific-2999. Where it is reported that Hotbird 13F has renewed the license for the future satellite Heinrich Hertz (H2Sat).

I suspected this was the reason it was placed at 0,5°E.

Around 5 April it had reached 0,5°E, considering that by ITU regulation, the satellite must stay at least 90 days to be able to renew the license... at the beginning of July it should start moving towards the definitive position of 13°E.

Satellite not move yet

 

[Marcus_21]

There are two test carriers at 0,5°E. Frequencies 11194,35 H and 11575,01 H.


11194,35 H.
