upper stage. The satellite was active for two years.
A second satellite,
SERVIS-2, was launched in 2010.
Experiments
Nine experiments were being conducted by SERVIS-1.
Results from the mission
All the modules on the satellite worked as planned.
The mission tested a number of electronic components, and determined that the rate of
single-event upsets at its 1000 km orbit was substantially less than had been expected from tests using heavy ion bombardment on the ground.
