ImageSat International (ISI) has decided to
shift the production of their A2 satellite to a block B series
model. EROS A2 had been scheduled for launch in the third quarter of
2001 on a Start-1 launch vehicle. Although production and
subcontracting work has already started on EROS A2, the decision is
not expected to disrupt production plans because of the high degree
of commonality between the two blocks. The upgraded satellite will
take about two years to ready for launch.
The EROS B series of satellites are initially
expected to cost more than the US$100 million it cost to produce,
insure and launch the EROS A1 satellite. However, after the first
few satellites are built, the price is expected to drop to about
US$70 million or so per satellite. EROS B1 has been scheduled for
launch in the second quarter of 2002.
The EROS A series satellite (A1) has a
resolution of 1.8 meters (6 feet), with a design life of about 6
years. The EROS B series models will have a resolution of 0.82
meters (2.7 feet) with a design life of 10 years.
ISI plans a constellation of eight high-resolution
imaging satellites. The company has contracted with Puscovie Uslugi,
Moscow, for the first three launches, on Start 1 rockets.
