MBSAT will
provide 2.400 kW RF power over 25 MHz of S-band spectrum to run
more than 50 channels of audio and video from 16 S-band
transmitters operating at 120 W. In addition, the satellite will
provide a 25 MHz Ku-band service link to transmit the broadcast
signal to terrestrial repeaters. The satellite will generate more
than 7.400 kW of DC power continuously throughout its 12 year
life. The satellite will deploy a 12-meter antenna reflector to
transmit the MBC programming. MBSAT's S-band payload, using MPEG-4
and AAC compression, will deliver CD-quality audio and TV-quality
video, in addition to various types of data. The system will use
code division multiplexing (CDM) MPEG-4 for video, and advanced
audio coding (AAC) for audio. The system will be able to broadcast
more than 50 programs simultaneously. The new spacecraft will be a
version of Loral’s space-proven three-axis, body-stabilized 1300
bus.
On-orbit delivery
of the spacecraft is scheduled for fourth quarter 2003 with
service expected to begin in early 2004. No launch vehicle or
financial details were released.
Mobile
Broadcasting Corporation was established to provide cars and
mobile terminals with digital satellite broadcasting for audio,
video and data services throughout Japan. MBC's new broadcasting
system was authorized by the Japanese Government and registered
with the ITU. The system capabilities and high performance quality
have been successfully verified in dense urban locations by
various field demonstrations in the Shinbashi and Ginza area of
Tokyo. Dedicated first generation receiver LSI chips have been
evaluated through extensive tests. The second-generation receivers
with high density LSI technology will be available by mid-2002.
