Express

Nine months after Gals 1 was launched, Express 1 was inserted into a nearly GEO orbit. The Express series spacecraft closely resemble the Gals spacecraft which share a similar spacecraft bus (Figure 4.42). Express will replace the widely used Gorizont spacecraft, and current plans call for deployments at 13 locations (40 degrees, 53 degrees, 80 degrees, 90 degrees, 96.5 degrees, 99 degrees, 103 degrees, 140 degrees, 145 degrees, 205 degrees, 322.5 degrees, 346 degrees, and 349 degrees, all East longitude) just for domestic needs and to support the Intersputnik Telecommunications Association. Additional Express spacecraft may be sold to foreign companies, e.g., Rimsat, Ltd. While the Express solar arrays are identical to those on Gals, the spacecraft bus has slightly smaller dimensions of 3.6 m by 6.1 m. A typical Express payload will include 10 C-band and two Ku-band transponders. Express 1 reached its checkout location of 70 degrees E at the end of October and was scheduled to be moved to 14 degrees W shortly after the start of 1995

Russia’s Federal Space agency expects to launch three Express-AM Communications Satellites during 2007. The Express-AM33 is scheduled for launch during September 2007 while the Express-AM44 as well as the Express-MD1 is scheduled for December 2007. The Federal Space Agency further expects to launch two more communications satellites Express-AM4 and Express-MD2 during 2008.
