SATELLITE
WATCH
Compiled by GARRY CRATT*
Apstar 2R
Apstar 2R was successfully launched
aboard a Long March 3B rocket from
the Xiachang launch site in China on
October 17. The satellite has 28 C band
. 16 K band transponders, which
and
can operate at 60W and 110W respectively. The satellite was expected to be
in commercial service by the end of
November. Officials from APT advise
that over 50% of the satellite capacity
has already been leased. The satellite
will occupy 76.5°E longitude.
Asiasat 3
The launch date for Asiasat 3 has
now been scheduled for December
12. This satellite will be launched
to occupy 105.5°E, initially to be
co-located with Asiasat 1 which will
then be moved to 122°E longitude.
We expect Asiasat 3 to be operational
by mid-January, if the launch goes to
schedule. Asiasat 3 will be launched
from the Baikonur Cosmodrome in
the Central Asian state of Kazakhstan
using a Proton launcher.
Asiasat has a contingency plan
should the launch fail and has purchased a “small” 6 transponder satellite, which could be moved to 122°E
to occupy the allocated slot, ensuring
it is not stolen by another (non-ITU)
operator.
Palapa C1

facility in Jakarta have realigned the
antenna on this satellite to provide
better performance in Australia and
New Zealand. Initial test signals
appeared on September 30, carrying
CNBC programming, disappearing
after a week or so. Palapa C1 is located
at 150.5°E longitude and will be worth
monitoring in future months.
Panamsat 2
Chinese broadcaster China Central
Television (CCTV) has begun uplinking from Beijing directly to Pas-2,
bypassing the double hop previously
used via Asiasat 1 and the Pas 2 uplink
facility in Hong Kong.
This means that CCTV can now uplink to both Pas 2 and Pas 4 from Beijing, considerably lowering operating
costs. The network has advised they
will be expanding to six channels. Pas2 viewers can presently see CCTV3,
4, 5 and 9, all broadcast in PowerVu
without conditional access.
loaded at rates up to 225Kb/s.
Optus B3
The Optus Aurora platform commenced testing in October. This platform will carry ABC and SBS (amongst
others) digital services, once the current
HACBSS BMAC service is terminated.
There is expected to be a gradual rollout
over the next 12 months.

Asiasat 2
New Guinea broadcaster EMTV,
which moved to Asiasat 2 late September on 3760MHz horizontal, will move
again as early as mid November. EMTV
intend to switch to non-conditional
access MPEG2, with SR 4333, FEC, on
4006/1144MHz vertical polarisation.
Most free to air digital receivers will
operate using these parameters.
Elsewhere on this satellite, Zaknet, a
Kuwait based group uplinking out of the
Subic Bay teleport in the Philippines,
has commenced their one way internet
service. Similar to Net On Air (which
has yet to commence service), the system uses a standard modem connection
for Internet requests and a special satellite receiver PC card connected to a
satellite dish forms the return path. The
combination allows data to be downDecember 1997 53
