"Phase-4" amateur radio transponders with Es'HailSat-2



(C)Es'HailSat


Qatar's Es'hail 2 satellite will provide the first amateur radio geostationary
communications that could link amateurs from Brazil to India. The satellite is
expected to launch by the end of 2016 and will be positioned at 25.5 degrees East.

AMSAT-DL President, Peter Guelzow DB2OS, has provided the following information:

Es'HailSat-2 will carry two geostationary "Phase 4" amateur radio transponders !!

As a result of a concept proposed by the Qatar Amateur Radio Society, Es'Hailsat,
the Qatar Satellite Company, have announced that their new, geostationary,
Es'HailSat-2 communications spacecraft will provide transponders for use by radio
amateurs. The spacecraft is expected to be ready for launch by the end of 2016.

Es'HailSat-2 will provide a 250 kHz linear transponder intended for conventional
analogue operations in addition to another transponder which will have an 8 MHz
bandwidth. The latter transponder is intended for experimental digital modulation
schemes and DVB amateur television.

Precise uplink and downlink frequencies remain to be finalized but the uplinks will
be in the 2.400-2.450 GHz and the downlinks in the 10.450-10.500 GHz amateur
satellite service allocations.

Both transponders will have broad beam antennas to provide full coverage over about
1/3rd of the earth's surface. Precise operational plans will be finalised over the
coming months but it is anticipated that only quite simple ground equipment will be
required to use this satellite.

A team of amateurs, led by Peter Guelzow DB2OS (President of AMSAT-DL) are providing
technical support to this ground breaking project which is expected to provide an
exciting new phase of activity for radio amateurs for the 21st century.


Linear transponder
2400.050-2400.300   MHz Uplink
10489.550-10489.800 MHz Downlink

Wideband digital transponder
2401.500-2409.500   MHz Uplink
10491.000-10499.000 MHz Downlink

[amsat-bb] The meaning of "Es'hail"

Recently we see many postings about the new satellite called "Es'hail 2".
Maybe you also wondered what the meaning is of "Es'hail".
I asked two 'friendly Arabic speaking colleagues' to fill me in.

It appears the satellite is named after a star, that we know as Canopus.
http://en.wikipedia.org/wiki/Canopus
In Arabic, Canopus is Sohail. But in the section 'Middle East' on
the Wiki page you see that there are many variants for this name,
including Sohayl, Soheil, Suhayl, Suheyl, etc.

Actually the name of our satellite is 'The Canopus', or in Arabic
'El Sohail'. In Arabic they tend to merge the two words, so it would
become 'ElSohail'. Since Arabs find it hard to pronounce the combination
of l and s, they drop the l. So it becomes 'ESohail'. An apostrophe is
added to emphasize the S: 'ES'ohail'. And since the o (or u) will be
pronounced anyway, almost 'automatically', it may be dropped.
So that is how we get 'ES'hail', or even 'Es'hail'.

As for the pronunciation of this satellite's name, probably 'eSohayl'
is best, with a short and soft e at the beginning.

So now at least we know what we are talking about   :-)

Thanks Nico for the nice explanation,  well done! 
Yes,  the company Es'hailSat and there satellite fleet are named
after Canopus. Es'hail 2 will be launched in first quarter 2017.
