Notes on GVAR data reception

Notes by Quorum

Subject: Re: GOES ground station antenna size
From: allan@qcom.com (Allan B. Bundens)
Date: Sat, 18 Nov 1995 17:01:25 -0600

NOTE: To fully disclose my position, I am not a casual observer.  I am an
owner of Quorum Communications, a manufacturer of GVAR equipment.


There are many factors that influence the quality of GVAR reception from the
GOES satellites, only one of which is the size of the dish.  The end result
of "specklies" or "dirty lines" can be a result of poor performance in any
of the system components.

First, antenna gain is very important and a 3 meter dish is capable of
providing better than 10E-8 BER with a good feed / downconverter and
reception system.  What is generally overlooked is that for any given
antenna to provide the best performance, the feed must be designed to
properly illuminate the dish for high efficiency.  Poorly matched antenna /
feed combinations will have low efficiency and exibit sidelobes that can
cause interference from other satellites.

Next in line, the downconverter or as is usually the case for GVAR systems,
integrated feed downconverter, must have a low noise figure.  Typical units
available today will have noise figures of about 0.8dB.  Better units with
noise figures of 0.5dB or less will allow a smaller antenna.  The
downconverter should also provide enough gain to overcome the signal
attenuation in the IF cable and still keep the system noise figure low.  It
is also important that the downconverter have 40 to 60 dB of image rejection.

Next, the receiver quality is very important.  GVAR data is transmitted
using BPSK and most receiver implementations use some form of costas-loop to
phaselock to the incoming carrier and decode the BPSK data.  Poor design
here can cause the detector to unlock generating bad data.  BPSK receivers
are in general easy to build but hard to make work reliably.  The receiver
should also contain an IF filter of the correct bandwidth.  The wefax signal
on GOES 8 is very strong and can interfere with the GVAR reception if the
receiver does not have a good filter at the GVAR frequency.  Also, the
receiver noise figure should be low enough that the system noise figure is low.

Next, the bit sync needs to lock up to the raw data stream and output
decoded clock and data.  While it is relatively easy to make a GVAR bitsync
that operates well under low noise conditions, it's a bit more difficult to
make one operate well under moderate to high noise conditions.  You should
look for a bitsync that provides performance within 1dB of theoretical.
Obviously, a poor bitsync design will output bad data.

Next, the frame formatter needs to lock up to the GVAR PN sequence and make
framed data available to the computer.  Again, it's easy to make one of
these that works well under good conditions, but it's much harder to get
good performance in the presence of noisy data.

Lastly, you need to pass the data to the computer without dropping any.
Again, there is an opportunity to drop data with a poor design here.

So, to conclude, you "could" get perfect data with a 3 meter dish if the
rest of your system was designed well and functioning correctly.  I can't
make any specific recommendations other than to suggest that you talk to
your system vendor for specific performance specs.

I am the president of Quorum Communications.  Our company manufactures
components that are used by a number of system suppliers in their GVAR
products, so my comments may be tainted with the perspective of any
manufacturer.  I can tell you that we use a Winguard 10' dish at our site
with a Quorum Integrated Feed / Downconverter (noise figure 0.8dB), Quorum
QC-5011 BPSK Receiver and Quorum Bitsync / Frame Formatter.  Our receiver /
bitsync has been designed and tested to provide performance within 1dB of
theoretical.  Our frame formatter uses a hardware correlator capable of
reliable operation with bit error rates as low as 3x10E-2 and we have a
built in bit error rate tester thats checks the 10000+ bit correlation
sequence against a known correct copy.

Our BER performance with this system varies from a low of 1x10E-9 to better
than 1x10E-11.  We suspect that this closely follows the BER of the uplink
system.  There are no sparklies, dropped lines or frame unlocks under any
conditions, even rapid scan mode.  We receive ALL of the data transmitted by
the satellite and transfer ALL of it across the bus to be written to hard
disk.  Our in house system uses a Pentium 90 running Windows NT.

While we would not recommend it, performance with a 6' dish is around 1x10E-6.

I hope this provides some help.

Notes by GTI

Subject:   Ground Station Equipment
From:      George T. Isleib gtielect@ptd.net http: //www.gtielectronics.com
Date:       June 27, 2000

NOTE:  George T. Isleib is the Vice President of GTI Electronics and director of Technical Operations. We
 manufacture GVAR and HRPT Ground stations.  The company is owned by Carol L. Isleib, Pres.

As with any complex system, there are many influencing factors that will govern the final results of
what can or cannot be expected from a GVAR ground station only one of which is the dish.   Any one of
several  items including dish size, noise figure, filtering, cable length, receiver, formatter card etc., can produce
unwanted results that include missed blocks, missing lines, sparklies etc., to name a few.

A typical dish size at this point in time is typically a 10 foot dish, however to clarify this a bit further, 
it is only true if the following is true as well.  The 10 foot dish must be fully illuminated and
the noise figure of the feed must be below 1 dB.  A patch feed does not actually fully illuminate the
dish regardless of its size and at high latitudes such as those above 40 degrees may not give the de-
sired results.  A dish using a feed specifically designed for the F/D of the dish and designed to fully
illuminate it with the proper noise figure will produce results that shows a 10 foot under these conditons
will outperform a 12 foot dish using a patch feed.

The integrated feed/downconverter should be constructed that both combline and bandpass filters
are located at the input stage of the pre-amp.  The downconverted GVAR signal should be amplified so
that the gain will allow the end user to locate the dish hundreds of feet from the receiver but the noise
figure of the pre-amp must be below 1 dB if you are to use a 10 foot dish with the properly designed
electronics that can fully illuminate the dish.  It should also have a bandpass filter at the downconverted
frequency to further eliminate extraneous interference.  The downconverter should have more than 60 dB of
image rejection as well.

The receiver decoding is extremely important to decode the BPSK data stream.  The favorite,
the Costas Loop configuration,  is a superb circuit for phaselocking to the GVAR data stream and decoding
the BPSK data.  Currently BPSK Costal Loop systems are very simple to construct and are one of the
most reliable to date.  By utilizing the proper filtering, bandpassing, and properly designed loop
circuitry, it can reliable produce data that approaches the theoretical maximum under the most severe
weather conditions.

GTI Electronics is located at 40 degrees N latitude.  We use an integrated feed/downconverter with
a true noise figure of .78 dB with a conversion gain of 68 dB and a 10 foot dish.  Our receiver/bitsync has given 
us 1 missing block in a 24 hour period consistently.  To put this in perspective, the GVAR data stream produces 
about 20 Gbytes of data in 24 hours!  The data shows no sparklies, missing lines, frame unlocking, etc., using
a typical 10 foot dish and our Feed/downconverter and bit sync card.  We use a Pentium III, 500 Mhz
computer and all data is displayed at 16 Million colors with a 256 Greyscale.  We ingest the data at the
full resolution of the satellite displaying it live as received along with the Sounder data as well.  All software 
runs under the WindowsNT platform and is multi-tasking and multi-threaded.  We have used our system on a 
7 foot dish with perfectly  usable data at our 40 degree N location with all ingesting and processing done on
a single desktop machine.

WEFAX systems

Many of the vendors listed above also supply low-cost WEFAX receivers. Other vendors (below) specialize in WEFAX and in exchanging information about it.

NOAA now posts the WEFAX schedules on the Web.

NOAA will change WEFAX image format beginning July, 1997.

NOAA will convert from analog WEFAX to digital LRIT broadcast format begiining with GOES-N in 2002. The rest of the geosynchronous satellite will do likewise.

Receiver notes

Subject: The Need for Selectivity (Was: Re: Pager Interference)
From: rbarth@noaa.gov (Richard Barth)
Date: Fri, 25 Jul 1997 12:57:54 -0400

Peter,

The answer you received from the Radiocommunications Agency is perhaps the
first thing spectrum regulators think of, and being on the fringes of that
business myself I undertand why.  In fact, given your use of what you
describe as an "ultra-broadband receiver", they may well be right.

There are primarily three things that create interference in situations such
as the one you describe, in which the interferer (here, above 138 MHz) and
the desired signal (here, 137. something) are significantly different in
frequency.  

(1) One is the possibility of an over-broad interfering signal.  A pager
probably requires no more than, say, 25 KHz of bandwidth, and any energy
outside that bandwidth should be reduced to an acceptable level (as defined
by the Agency.)  Given that you see pager energy down to 137.7 MHz or so,
they may be putting out excessive spurious energy, in which case they may be
responsible for curing the problem.  But, see (2).

(2) If the receiver (and this includes spectrum analyzers) are over-broad,
they may receive a clean out-of-band signal and, because of their own
non-linearity, generate hash IN THE RECEIVER which disrupts the desired
signal.  The receiver, to avoid this problem, must have sufficient dynamic
range to avoid non-linearity or must filter out the interferer.

(3) A strong (though clean) interferer may cause the receiver AGC to
attenuate the desired signal to the point of unreadability.

The kinds of satellite you're looking for aren't rock-crushers.
Particularly during certain parts of the pass they're probably pretty weak
in comparison to interference. Therefore, they're vulnerable to all of the
above problems.  A filter is one way to extend the useful life of an overly
broad receiver, if its lack of selectivity is in fact the problem.  I expect
there are others in this group who know more than I about filters, so I'll
leave it to them to provide recommendations on availability and sources.

One point I would like to add is that this problem is likely to get worse as
time goes on.  There is more and more pressure from industry to use what up
to now have been considered "meteorology bands."  The Mobile Satellite
Service (MSS, a.k.a. "Little LEOs") is already using 137-138 MHz and the
current lack of problems is due primarily to the fact that they haven't
gotten around to doing it in a big way.  Only 8 or so MSS satellites are
currently flying here.  There will eventually be dozens and may approach 100
depending on the decisions made by licensing authorities (of which I'm not
one, so please don't preach to the choir.) Similar commercial use is
currently authorized (by ITU spectrum allocation) in 400.15-401 MHz planned
for use by U.S. metsats in a few years, and in 1675-1710 MHz now used by
Japanese S-VISSR, by U.S. GVAR, WEFAX, EMWIN, HRPT etc., and by radiosondes
around the world.  Unless national regulatory bodies recognize the need for,
and protect existing meteorological activities the problem will only get worse. 

Earlier, "Dr. Peter N.H. Davies" (P.N.H.Davies@sussex.ac.uk) said:
*
*I was reminded, by a recent wxsat-l mail query (Richard.Whitcombe, "A
*few beginners questions", 11/7/97), that quite a large proportion of the
*UK 137 MHz amateur satellite band is apparently permanently masked by
*100W pager interference at 138+MHz.  
*
*Last week I had a brief opportunity to talk to some members of the UK
*Radio Communications Agency (RCA), who police our airwaves, about this
*problem.
*
*Problem!  What problem!  Apparently amateurs are using inferior equipment!
*
*Now, as a newcomer myself to radio (and in particular, satellite)
*reception, I can quite believe I am, but didn't fully appreciate it. 
*I use an ultra-broadband receiver, which gives me enormous receiving
*flexibility, but I think I have probably been lulled by the apparently
*high frequency discrimination into somehow expecting a better intrinsic
*performance (a 'spike' at 137.50, 137.62... would be nice). In practice,
*using a spectrum analyser, I can see an enormous, variable 50dB pager
*'curtain' spreading down as far as 137.7 MHz.
*
*If this is entirely an artifact of my equipment, then I'll have to learn
*how to filter it - or live with it.  If you know otherwise, then the RCA
*(New King's Beam House, 22 Upper Ground, London, SE1 9SA), although
*under-manned and under-funded, would like to know; they have enormous
*powers (above police and customs, apparently) to enforce frequency
*spectrum conformance.
*
*Any useful filtering suggestion, anyone?
*All the best,           Peter.

Anita Perryman wrote re- GMS-4 reception in Indonesia
Anita,
The dish is certainly the least of their problems.  There are plenty of dishes 
about in Indonesia, most of them between 1.5 - 2m.  They are used for TVRO 
reception and are more than adequate.  In comparison to Meteosat an GOES
imaging, the fundamental problem with GMS is that the receiver requires a
bandwidth of 260 KHz and a commercially available receiver generally does not
cover this.  If your colleagues have experience with electronics, especially
radio, a very elegant solution is to take a commercial FM broadcast receiver
and remove a few turns from the oscillator coil to adjust the coverage to 137.5
MHz.  Common practice is to use a "coffeecan" type feedhorn, which is easy
to home brew, followed by a 1.7 GHz LNA, which probably will have to be a
commercial unit, unless your friends are very well versed in matters SHF and
have the necesary test gear.  The pre-amp is followed by a down converter to
137.5 MHz and then into the receiver.  Again one could build a downconverter
ones self given the required skills.  Alternatively the downconverters
available in the UK would be suitable for GMS-4 keeping in mind that the
operating frequency of GMS-4 is 1691.00 MHz.  Once you have a signal, it will
need to be decoded.  Not surprisingly the Australians porbably would be the
best source for hardware and software.  A fellow in Brisbane produces an
excellent decoder board for about AU $ 100.00 (I think) and in the same
City you will find Michael Delahunty, who has produced software for decoding
the GMS series in addition to the usual APT at a more than reasonable price.
If other software and decoder boards are already available, such as the 
Timestep kit, these are fine. Again if you require a ready made down converter 
and 260 KHz bandwidth receiver another chap again in Brisbane by the name of 
Peter Williamson produces these.
BTW GMS-4 is to be replaced sometime in February this year by GMS-5, which 
will carry a further 2 spectral ranges for images.  Note that the above set
up refers to the low resolution GMS-4 images which are transmitted on the 
hour evry hour.  The high resolution images which you sometimes get in Europe
re-transmitted from GOES or Meteosat require much more sophisticated gear,
running into megabucks.
If you need any more information re the guys in Oz, sent me a message and I
might be able to give you an E-mail address of at least one of them

S-band Transmitters

Date: Tue, 11 May 1999 07:25:10 -0400
From: "Warren F. Dorsey" <wdorsey@nesdis.noaa.gov>
Subject: Re: GOES Satellite Transmitters

Are you asking for the S-bnd XMTR's.  There are only two of recent date and one of these is presently building our new ones.  Our S-band manufacturer's are:

	1.	COMTECH Microwave Corp.
		105 Baylis Road
		Melville, New York  11747
		They also make the solid 
		state command XMTR for the 
		new 13M POES antennas

	2.	NEXCOM, Inc. and RSI (formerely PTI)
		4343 Fortune Pl.  Unit C
		Melbourne, FL  32904

		RSI/PTI Model 2100KS
		709 Anchors Street, N.W. 
		Fort Walton Beach, FL  32548

We also have some old Enterprise Electronic corp. S band XMTR's that will be phased out when the new NEXCOM/RSI units are installed.
The older units by EEC and Comtech XMTRs used a Varian Tube Model number 7795A-D.  The new XMTR units will use a Thompson 2451D.
