 Galaxy
3C was successfully launched by Sea Launche's Zenit 3SL at 22:39
UTC on June 15. The spacecraft will be positioned at 95°W. The
spacecraft is expected to become operational by Fall 2002. Galaxy
3C will replace Galaxy 3R, where it will complement the  Galaxy
8i satellite, which will also soon be replaced.
The 4850 kg
(10,690 lbm) Boeing built Galaxy 3C carries 24 C-band and 52
Ku-band transponders. The spacecraft uses the BSS 702  satellite
bus. The satellite is planned to have 15.000 kW power at the end
of its 15 year design life.
A
design flaw detected in concentrator devices on the solar panels
of the first six BSS 702 spacecraft that were launched has been
corrected with this spacecraft. The concentrator design was
expected to increase power production, but on-orbit their optical
qualities have been found to be slowly degrading, gradually
reducing the power being produced by the solar arrays. Boeing
removed the concentrators from the 702 design, and has added a
sixth panel to the solar arrays to correct the problem.
