GE-4

 1999-060A


GE-4 replaced Spacenet 4 at 101W. GE 4 used an A2100AX bus for video and data services for GE American Comms. Inc. Launch by Ariane Nov 13 1999. Cover both Canada and USA with C and Ku-band wide beams, plus a Ku-band beam for S America. Mass 3903 kg launch, 1755 kg dry. Size 6.23h 26.8m span.

GE 4 was renamed AMC 4. In 2008, a partial solar array power loss led to C-band users being transferred to AMC 2.

In 2010 AMC-4 was moved to 67W to reserve an Andean-nations orbital Simon Bolivar 2 slot.

Landsat 7

 1999-020A


Landsat 7 was built by Lockheed Martin's LMMS/Valley Forge plant. It used the Tiros-N class bus and was similar to Landsat 6. Landsat 7 carried a single instrument, the Enhanced Thematic Mapper Plus (ETM+). built by Raytheon/Santa Barbara. Launch of L7 was delayed in 1998 due to problems with the ETM+ power supply. 4.3m long, 2.8m dia. Launch mass 1969 kg. Launched by Delta into 10am SSO with 16-day repeat cycle. Primary archive is USGS/Eros, Sioux Falls, SD. Flight ops from GSFC until 2001 Jan. In Jan 2001, USGS assumed responsibility for the Landsat 7 FOC at GSFC and took over some functions at Sioux Falls.

The satellite makes stationkeeping burns every 40 days to keep the ground track stable.

In 2003, the ETM camera suffered a component failure causing data gaps in images, but the data was still usable.

MBSat

 2004-007A


Mobile Broadcasting Corp. (MBCO) of Tokyo and SK Telecom of Seoul launched MBSAT for digital audio and multimedia at S-band to mobile users. SS/L 1300 bus with 12-m S-band TRW mesh reflector similar in style to the Thuraya dishes. Payload control centers in Tokyo and Seoul. Satellite control centers Space Port East, Ibaraki area (prime) Japan and Space Port West, Yamaguchi (backup), Japan, operated by Space Comms. Corp (SCC).

The satellite was not registered with the UN by either Japan or South Korea but by the US.

Launch mass 4143 kg, 1760 kg dry. Launch by Atlas 3 AC-202 with single engine Centaur and 14' fairing.

MBSAT was known as Hanbyol (

\uni{ 한별,Big }{ }
Star) in Korea. (or, Araeahanbyu).

MBCO went out of business in 2009, but TU Media, the SK Telecom subsidiary using MBSAT, remained to operate the satellite for Korean users. In 2013 the satellite was bought by ABS and renamed ABS-2i.
