'SPOT,' 'LANDSAT' COMPATIBILITY SEEN BENEFITING FRANCE -
Paris AIR & COSMOS in French 21 Mar 81 pp 53-54
~Article by Pierre Langereux~
~ ~Text~ The future looks favorable for the putting in place of an operational
"SPOT" ~Earth Observation Probe System~ system, considering the inherent features _
of the French satellite (high resolution, stereoscopyj and its operating charac-
teristics (Band X transmission), which make SPOT receiving stations compatible `
with "Landsat D" receiving stations. Ttiis compatibility between the French and
American systems was indeed planned beginning as far back as 1978 by the CNES
~National Center for 5pace Studies~ and NASA. The cansequences are significant. _
They will make the SPOT and Landsat D systems the two major space teledetection �
- systems worldwide.
_ Currently, there are 12 Landsat stations in service throughout the world; five _
others are being built, and eight new ones are being projected between now and
1985, bringing the to~al of Landsat receiving stations to 25, of which some 15
will be compatible with the SPOT system when it goes into service. Eventually,
all Landsat stations will be compatible with SPOT, since the new Landsat D genera- _
tion of I;merican satellites will all operate only in Band X.
These stations will be the access key to future Landsat D and SPOT teledetec- -
~ tion satellite operational networks to be placed in service in the coming years.
France will thus occupy the place of one of the world's principal suppliers of -
future teledetection data, alongside the United States! -
Landsat Shortcomings
The American Landsat system, the world's first space teledetection network, has
operated 9 years now without interruption. Three experimental satellites have
been launched successively. The first, Landsat 1, launched in July 1972, ogerated
_ until February 1978, that is, 5 years (ins tead of the expected 1 year). The
second satellite, Landsat 2, launched in January 1975, was restored to service in
June 1980 after an interruption of several months. The third satellite, Landsat
_ 3, launched in March 1978, broke down operationally in early 1981.

Overall, Landsat satellites have photographed more than 800,000 "scenes" (a series
~ of images of the same zone taken on different wavelengths) in standard format (185
km on a side) covering all emergent land masses almost entirely in several spec-
'tral bands (visual and infrared) with an earth-level resolution of 80 m. More
- than 60 p~rcent of these images were acquired by non-American station~, and 36
~ percent of the sales of Landsat data were made to foreign users.
- This result obtained by the first generation of American teledetection satellites
is impressive. It does not completely satisfy users, however, for several
reasons:
--the space resolution (80 m) and the geometric accuracy arp considered inadequate
for most mapping work;
--the repetitional rate of observations (18 days, then 9 days) of the same site is
not adequate, especially for the surveillance of vegetation and pollution;
--the choice of spectral bandwidths (0.5-1.1 microns in the visual and 10.5-12.4
microns in the infrared ranges) is not optimum for the surveillance of vegetation;
_ --and the data supply delivery time (6 weeks) is much too long for certain users
who need a fast restoration (48 hours).
The New Landsats
The United States has therefore prepared a new generation of improved teledetec-
tion satellites: Landsat D1 and D2--the fourth and fifth of the series--which are
- to be launched by year-end 1982 and year-end 1983 respectively. The Landsat D2
satellite is to be equipped with a new instrument (Thematic Mapper) for shots
. with a resolution of 30 m and spectral bandwidths more suited to thematic mis-
sions. However, Thematic Mapper data wi11 not be distributed operationally (50
scenes/day) before 1985, according to NASA.
In 1979, the American government ~lso deci8ed the creation of an operational
- teledetection satellite system under the NOAA ~National Oceanic and Atmospheric
Administration~, which was already responsible for the American system of civilian
meteorological satellites.
On 20 June 1980, the NOAA submitted to Congress a three-phase plan--extending to
the year 2000--for the creation, beginni~g in 1982 and using Landsat D satellites,
of a system that would not be fully operational with a new generation of satel-
lites until 1989. The cost of this future operational system--variable between
$1 billion and $10 billion over a total period of 10 years depending upon various
assumptions~--is to be self-financed by revenues from the sale of images, esti-
mated at $100 million-$400 million annually and based upon a general and
substantial (3 to 5 times current price) increase in image marketing rates.

SPOT Images at 1 Franc/Km`
France, for its part (see AIR & COSMOS no. 850), beginning with its first earth-
probe satellite, SPOT 1, to be launched in 1984, plans to create an operational
network of SPOT observation satellites calling for successive launchings of four
or five satellites to maintain the system in se r vice over a period of 10 years.
~ The operating cost of such a system is estimated to be around 1.5 billion francs
- (1980 prices), not including the system install a tion cast, which will come to
around 1 billion francs with the SPOT 1 satelli te and associated earth segment.
The launching of the second satellite, SPOT 2, planned for 2 years after the first
- one (1986), will cost an estimated round figure of 350 million francs; it could
even be financed by the CNES. Beginning with the tY~ird satellite, however, the
system must become self-financed by revenues from the sale of images, which are
estimated by the CNES to be around S40 million/year. -
The CNES market studies project possible annual sales of around 100,000 SPOT
scenes (3 images at 20-m resolution and 1 at 10 -m resolution) at a price of around
2,500 francs ($500) per scene, which would be substantially lower than the price
- of data from the future Landsat D operational s atellites. SPOT high-resolution
data--selling at a price equivalent to 1. franc/km2)--could thus compete directly
against high-altitude aerial photography (10-15 francs/km2).

NEW, SPECIALIZED SATELLITE SERVICES DISCUSSED
Paris AIR & COSMOS in French 28 Mar 81 pp 37-38
[Article by Pierre Langereux: "Space Telematies"]
[Text] Development of the New Specialized Services Using Satellites
The telecommunications satellites are, as is known, simple space relays whose best-
known uses are the retransmission of telephone communications and television pro-
grams, as well as transfer of data between computers. But other and more spe~ial-
ized information can also transit via s~atellites, whether moving (in low orbit) or
geostationary (at 36,000 km altitude). Jean-Claude Husson, director of the Toulouse _
Space Center of the CNES [National Center for Space Studies], has cited some 10 of
_ these new applications, either under way or proposed.
Direct TV
- To the present, no TV viewer in the world receives directly the television programs
- transmitted by satellites; L�he signals are first picked up by large national sta-
tions and then sent out over the conventional networks (radio waves, cables, etc) to -
the viewer, under the control of the television administrations or companies. The
imminent advent of the direct remote-broadcasting satellites is going to overturn
this situation. The programs transmitted by a central station to the satellite will
be broadcast directly to the TV vie~:~r via small individual or community antennas. -
It will thus be possible for a TV program to be broadcast directly to 100 million
households in Europe (the case with the Luxembourg satellite).
The progress achieved in satellites (power of 6 W for 5 channels, TOP of 200 W and
more, stabilization to better than 0.1�, large multisource antenr~as, high frequen-
cies, etc) makes it possible as of now to build such satellites, the mass of which
will reach 1 to 2.5 tons (in transfer). The new launchers (Ariane and Shuttle) will
be able to put these satellites into geostationary orbit. Practically all coun-
tries, if they have the means and the know-how, will be able to make use of direct
TV via satellite. Indeed, almost 1,000 possibilities of direct transmission over
a nearly 250 zones in the world have been planned for by the international telecommun-
ications organization (ITU [International Telecommunication Union]), on the basis of
35 orbital positions, to cover more than 150 countries individually.
Retransmission of Meteorological Images
The geostationary weather satellites, such as GOES in the United States and Meteosat
in Europe, the principal function of which is to take pictures of the earth and of -

cl.ouds, also serve to rebroadcast the processed images to the community of users. -
Thus, the meteorological images received and processed in Darmstadt (FRG) are re-
broadcast by the Meteosat satellite in analog form ([JEFAX) over 2-meter stations
(uDUS [expansion unknown)) or in digital form to 4-meter stations, on the L band
(1.6 GHz) gigahertz]).
_ An experiment in distribution of weather data via satellite to AFrica is going to be _
conducted by the ESA [European Space Agency] with the Sirio 2 satellite, the launch- _
ing of which is.~lanned for 1982. This_experiment, which is aimed at supplementing the
conventional weather-data distribution network, will make it possible to transmit at
the rate of 100 to 2,400 bits per second on the L band to 1.5-~meter and 2.5-meter
stations. -
This system of broadcasting of weather data via satellites could later be provided
on a permanent basis with the future operational Meteosat satellites. -
Broadcasting of Images and Remote Detection
- The images of the future French remote-detection satellite Spot could be broadcast
far more rapidly in Europe with the aid of the 'French telematics satellite Telecom 1.
These images, which will be received in Europe by the French station of Aussaguel -
and the Swedish station of Kiruna, will necessarily have to be preprocessed by a
specialized center at Toulouse before being rebroadcast to the users, via the Spot-
Image company. But exploitation of these images will require of the users remote -
consultation of the Spot photolibrary, with transfer of a simplified image (quick- _
look) representing a flow of 256 Kbits/sec. In order for consultation to take no
longer than 10 seconds, a flow of 100 Kbits/sec will be required. But for retrans- -
mission of a"scene" (three Spot images in the different wavelengths) in less than -
1 minute, more than 3.6 Mbits/sec will be necessary, and to do so in less than 10
- seconds, nearly 34 Mbits/sec will be required. This would justify the use of a
specialized-telecommunications satellite such as Telecom 1.
Later, it would even be possible do the transfer of processed images automtically by
~ computer iii order to provide an orthophotomap directly to the user. '
Collection of Data and Localization
The CNES placed in service several years ago an Argos operational system for data- -
collection and localization of automatic beacons throughout the world. This system -
operates automatically and is used by several dozen French and foreign users _
who take measurements in the most diverse places: atmosphere, ocean, rivers, ice-
bergs, volcanoes, from balloons, ships, buoys, platforms, etc, and even by means of
- animals (bears, dolphins, sharks, turties, etc). -
_ The CNF.S' Argos system simply uses a special piece of interro~;ation equipment (EMD
[Marcel Dassault Electronics)J mounted on American weather satellites of the Tiros N
series which revolve in polar orbits. The data, processed by IRIS 80 computers at the
Argos center in Toulouse, are then sent to the user by simple telex call (No 530 255),
sometimes with the aid of telecommunications satellites of the INTELSAT network.

The Meteosat weathe r satellite can also be used for data-collection, but only in the
satellite's zone of visibility and with an output (at 400 P'IIiz) that req>>ires bigger
beacons.
Relay Satellites
The networics of ground stations fo~ control of satellites in orbit--doing the func- -
tions of telemetry, remote control and localization--are destined to disappear in
the future so as to permit better exploitation of the frequency spectrum. They will
_ be replaced by relay satellites which will provide for the service connections be-
tween a central sta tion on the ground and the satellites in low orbit (200 to 2,0~0
km) or geostatioiiary orbit (36,000 km).
NASA has already s tarted the setting-up of such a system with the future TDRSS relay
satellites to be launched in 1982-1983. Two TDRSS geostationary satellites separ-
ated by 130� longitude will thus be able to provide S-~and and K-band connections,
with single or multiple access and with flows that can reach 300 Mbits/sec. NASA's _
"Space Shuttle" will be one of the principal us~rs of the TDRSS network, as well as
the future Landsat D remote-detection satellites.
- The CNES has also p lanned for the placement in orbit of a STAR relay satellite for
control of the future French, and possibly European, satellites.
Teleconferences _
The use of several teleco~mnunications satellites makes it possible to organize re-
' mote conferences among several cauntries on different continents. Experiments or
demonstration projects of this kind have already been carried cut, since 1978, with
the French Symphonie, the America ATS 6, and the Canadian Hermes satellites.
Symphonie has msde possible international teleconferences between France, the United
States and Canada, while ATS 6 has provided for retransmission to 48 stations in the
United States; Hermes has done the same service between the United States a.Rd
Canada.
Other operations a re planned on the national level, notably with the French satel-
- lite Telecom 1, one channel of which is specifically devoted to videoconferences
(remote conference s with sound and image).
Time Transfer
- A very original us e of satellites is time transfer and synchronization of~atomic
- standard-chronomet ers at various points on the globe.
Until now, time wa s distributed with a precision of only 1/1,000 sec, using radio-
electric propagati on of time signals around the earth, by reflection from the iono-
sphere.
Satellites now mak e it possible to do much better. The American Transit militarv
navi~;ation satellites are already distributing time signals with a precision of 50
to 100 microsecond s. But experiments done in recent years ~1976-1980), notably with
the Franco-FRG Symphonie satellites, have made it possible to achieve precisions of _
10 to 100 nanoseconds. These experiments have taken place among France, the FRG,
Canada, India and China.

- Precisions of 1 to 10 nanoseconds throu~hout the world could even be achieved by us-
ing the geostati~nary satellites, at 4-6 GHz for in~ercon~inental connnectiona and
11-14 GHz for national connections.
Furthermore, the ESA is preparing a nec? atomic-clock synchronization experiment cfn
an intercontinental scale with the Sirio 2 satellite.
Amateur-Radio Satellites
Ham radio operators throughout the world are also among the most assiduous--and most
misunderstood--users of the telecommunications satellites. It is estimated that a -
million ham radio operators are presently using the specialized satellites devoted
to them for their long-distsnce connections.
= In che last 20 years (since 1961), 9 Oscar amateur-radio satellites have been _
- launched by the American association AMSAT [expansion unknown]. Ttao American satel-
lites are still operational at present (on the frequencies of 145 and 435 MHz). The
launching of a new FRG amateur-radio satellite failed last year with the loss of the -
Ariane launcher.
But the CNES is preparing for 1985 thQ launching of a French amateur-radio satel- ~
lite, Arsene.
Search and Rescue
The satellites are also going to be used for search and rescue of airplanes and
ships in dxstress; they will make it possible to ensure security of reception of
distress calls as well as localization (with precision of a few kilometers) of the
site of distress, thus facilitating search-and-reacue operations.
An experimental system will be sPt up for the first time on a world scale in 1982,
within the framework of cooperation among France, Canada, the United States, the
USSR and Norway. This system will utilize in particular some specialized Sargos
(EMD [Marcel Dassault Electronics]) distress-signal reception and localization
_ equipment mounted on American Tiros N polar weather satellites, as well as analogous
equipmenton board specialized Soviet satellites of the Intercosmos 21 type. This
system will thus bring into association the Western SARSAT [expansion unknown] sys- ~
tem and the Soviet COSPAS [expansion unknown] system.

BRIEFS -
NEW DIGITAL EXCHANGE--Turin--Within the framework of the modernization of the Ital-
ian telephone network, the Higher Institute of Post and Telecommunications has ap-
proved the AFDTI [expansion unknown] electronic sutomatic switching aystem, using a
- digital recorded program, that has been entirely designed and developed by Telettra
at its establishment in Gorgonzola. There are already four specimena of this type -
of digital electronic exchange for public telephone transit--the firat approved in
Italy--installed in the SIP [Italian Telephone Company] network: at Turin, Milan,
- Rome and Naples. By vistue of this new electronic system, it will be possible to
start up the voice and data (computer-co~nection) network whereby the users request- _
- ing it will be able to use throughout the national territory advanced aervices such
- as the multifrequency keyboard with the possibility of abbreviated dialing, complete
documentation of charges, communication of data even with fixed deatination, and
finally--most important of all--through-dialing for international and intercontinen-
tal connectione from the entire country. After state-agency approval, which is ex- _
- pected to be granted very shortly, the Italian system will be capable of offering
services that will be among the most advanced in Europe. The voice and data network
