                    PanAmSat Tops Record

     PanAmSat has beamed nearly 20,000 hours of special
events and   news coverage over its global satellite system
during the first three   months of 1997. Total special
events and part-time transmission traffic for the quarter
was the highest in PanAmSat's history.
     Among the events transmitted during the quarter over
PanAmSat's global   satellite system:

"    Continuing coverage of the Peruvian hostage crisis.
 Since the hostage situation began in mid-December 1996,
 PanAmSat has provided almost 13,000 hours of service over
 its PAS-1 and PAS-3 Atlantic Ocean Region satellites for
 more than 30 broadcasters, including ABC, CBS, CNN, Fuji,
 NHK, Nippon TV, TBS and TV Asahi.

"    Live, ongoing coverage of the Cricket Tour of the West
 Indies over PAS-3 for nearly 30 Caribbean Broadcasting Union
 member stations

Live coverage in March of Formula One races from
 Sydney, Australia, uplinking to the PAS-2 Pacific Ocean
 Region satellite and from Sao Paulo, Brazil, over PAS-3 to
 Germany for RTL and DSF.

"    Live transmissions of the Academy Awards broadcast from
 Los Angeles to Europe, Asia and Latin America for ABC, BBC
 and CBS. The awards ceremony on March 24 was broadcast to
 Latin America over PAS-3, to Europe over PAS-1 and to Asia
 over PAS-2.

"    Live satellite news reports of the Albanian political
 crisis over PAS-1 for Antenna TV of Greece.

"    Live coverage of the Senior Slam Golf Tournament at Los
 Cabos, Mexico, in late February for Turner Broadcasting
        PanAmSat-Hughes Communications Galaxy Merger

     The proposed merger of PanAmSat and the Galaxy
satellite services business of Hughes Communications, Inc.
has moved another step closer to completion when the FCC
formally approved the transfer of orbital slot licenses this
week from both PanAmSat and Galaxy to the new, combined
PanAmSat Corporation.
     The FCC action is the second affirmative decision by a
U.S.  federal agency reviewing the merger.  In December 1996
the United States Department of Justice (DOJ) permitted a 30-
day review period to pass without taking action to halt the
merger or imposing an additional review period.  PanAmSat
and Galaxy had previously filed with the DOJ and the Federal
Trade Commission under the Hart-Scott-Rodino Antitrust
Improvements Act.  At that time, the DOJ claimed
jurisdiction over the antitrust review.
     The final federal clearance necessary for the merger to
conclude is expected shortly from the United States
Securities and Exchange Commission.  The final step will be
approval by PanAmSat shareholders.
                General Instrument at the NAB
         General Instrument demonstrated the company's video
compression technology, introduced six new satellite and
terrestrial receivers, demonstrated a new broadcast receiver
design, displayed DTH solutions world-wide, and highlighted
three new subtitle vendors during the annual convention of
the National Association of Broadcasters in Las Vegas.
               Under the name "Digital Density", GI
demonstrated it's 16-to-1 digital video compression
technology by setting up 16 TV monitors to receive 16
separate compressed feeds, equivalent to the capacity of a
single 24 MHz satellite transponder.  Three of the 16
digital feeds featured multilingual subtitles prepared by
Cavena Image Products AB; Screen Subtitling Systems, Ltd.,
and SOFTNI Corp.  The subtitles display was processed in
real time by GI's commercial satellite receivers.
               Another demonstration of 10:1 broadcast
quality compression with the Magnitude MPEG-2/ DVB System,
featured real time compression of 10 video channels in a 27
MHz transponder, including one channel of digital local
insertion.  For this demonstration nine video channels were
compressed at variable rates using the StatMuxPlus software
     Also demonstrated in the DVB arena were a family of new
satellite receivers.  These are Magnitude consumer receivers
for DTH applications and commercial models for cable head-
end delivery, broadcast distribution, distance learning and
private network applications.  Both units are MPEG-2/DVB
compliant and offer high speed data options.
              Another demonstration featured private network
downlinks from Nebraska Educational TV Network, Fordstar
Dealer Communications Network and Georgia Public Television,
showing such private network applications as distance
learning and business television.

                   Lotte Data Communications

     General Instrument  said that Lotte Data Communications
Company of Seoul, Korea will purchase 200,000 Magnitude DVB
consumer satellite receiver kits for the first Direct-To-
Home (DTH) use in Korea.
     The contract for the just-introduced Magnitude SR-3350
was signed by General Instrument's Magnitude Compression
Systems, Inc. subsidiary (MCS) and the Lotte Group of Lotte
Data Communications Company.  Financial details of the
transaction were not disclosed.
     The receivers will be used for Korea's first DTH
service, which is presently scheduled to be launched this

      Scientific-Atlanta Delivers First IRIDIUM terminals

     Scientific-Atlanta engineers have delivered three earth
terminals that comprise the first satellite communications
gateway for the IRIDIUM global communications system.  The
gateway, installed in Tempe, Arizona, will undergo further
integration and test activities before completion in June.
     Scientific-Atlanta's Communications and Tracking
Systems Division is under contract to build 57 earth
terminals.  Forty-three earth terminals will be used in
communications gateways; 14 earth terminals will be used in
the system control segment that regulates the orbit of the
IRIDIUM satellites.  System control segment earth terminals
have been installed at ground sites in Iceland, Canada, and
Hawaii, as well as at a testing site in Chandler, Arizona.
     The communications gateway terminals comprise a 3-meter
(10-foot) dish inside a 5-meter (17-foot) radome and provide
the communications link via Ka-band (19.4-19.6 GHz for
downlinks, 29.1-29.3 GHz for uplinks) between the IRIDIUM
constellation of low earth orbit communications satellites
and public-switched telephone networks.  This network
function makes communications possible between IRIDIUM
telephones and other telephones around the world.
     The company also has a contract to provide maintenance
and support to the ground stations.  Gateways will be owned
and operated by Iridium, LLC.  investors.  Additional
installations are scheduled for Europe and South America
later this year.
         Vyvx Advertising Distribution Services Upgrade

     Vyvx Advertising Distribution Services will have
converted its satellite network to the digital format by
April 21.  Nearly 600 broadcast stations and cable systems
across the nation which currently receive commercials from
Vyvx are in the process of upgrading to the new digital
receiver decoder.
     The digital conversion package includes a General
Instrument DSR4500 digital satellite receiver, Vyvx Station
Interface Unit and associated cables and documentation.
Since the new units are "plug and play" compatible with
stations' existing satellite, audio, video, printer and VTR
interfaces, the conversion to digital will be immediate and
     The package has been shipped to each television station
on the network previously serviced by Cycle Sat, Inc., which
was acquired by Vyvx, Inc. in November 1996.  The digital
service will use GE-1, transponder 20.
     Vyvx also announced beta network test plans for a new
compressed dedicated fibre video transmission.
     This service, using MPEG II compression technology from
Nortel, will be carried over Vyvx's 11,000-mile coast-to-
coast fibre-optic network, enabling multiple video signals
to exist within the same DS-3 transmission path.

     The MPEG II compressed dedicated video service will
occupy a bandwidth of 6.312 M/bs or DS-2, which can be
naturally multiplexed into a DS-3 or 45 M/bs stream.  This
allows for cost-effective and simple drop, add, and pass
capabilities of MPEG II video signals within the DS-3
     The service initially will be available in specific
test markets where demand is highest.  The seven cities
involved in the test include New York, Chicago, Denver, Los
Angeles, Nashville, San Diego and Washington.  Vyvx will
test the technology and service infrastructure for 60 days,
beginning April 30.
     The purpose of the beta analysis is to test the
capability of the MPEG II equipment to be remotely
monitored, alarmed, switched and restored, if needed.  The
success of the test will be measured by the acceptable
quality of video received by customers and the ability of
the service to be fully controlled and restored by Vyvx.
     And in the analogue word, Vyvx will launch a full-
analogue, occasional-use video satellite service on April
17, with high power, simultaneous Ku-band coverage of North
America, South America and Europe.
     The hub of the new service is Vyvx International's new,
fully-meshed transponder on the INTELSAT K.  Making use of a
special "broadcast mode" configuration in the satellite,
this transponder receives from either of the INTELSAT K
uplink beams and projects to all of the downlink beams
simultaneously.  Despite covering North and South America
and Europe, the downlink beams maintain the normal power of
INTELSAT K transponders.
     Because all satellite beams remain switched on at all
times, operations for intercontinental broadcasting become
as simple as a local feed.  Whether a broadcaster is
transmitting from a mobile or fixed earth station, the
uplinker can see a return signal from the satellite_even
when the uplink is in Europe and the destination downlink is
in South America, or the uplink is in the USA and the
downlink in Europe.
                Groupe AB and Radio Nostalgie

        Groupe AB has signed an agreement with Radio
Nostalgie, one of the top five FM radio stations in France,
to launch a thematic music television channel under the
Nostalgie brand name.
     The Nostalgie Channel, which is 100% owned by Groupe
AB, will be broadcast on AB Sat's digital TV service and
will replace the Melody channel in AB Sat's basic
programming package.  Under the agreement, Groupe AB will
pay Radio Nostalgie for use of the Nostalgie brand name on a
per subscriber basis.  In addition, the sale of advertising
space on the new channel will be subcontracted to Radio
     Under a separate agreement, Groupe AB has agreed to
provide the Nostalgie Channel to Canalsatellite Numerique,
Canal Plus' digital satellite service, which will also
broadcast the channel in its basic package of digital TV
