Validation of electrical power system using Electrical Test Bed of GEO satellite

The electrical test bed (ETB) integrates the test environment, which is required for acceptance tests of system level, prior to FM testing. This ETB is composed of engineering version units of spacecraft BUS, which are laid on the laboratory table. It uses for the validation of system level functions and interface between each subsystem. The ETB also supports early functional and limited performance checkout of electrical subsystems and provides the environment for the verification of the Flight Software including AOCS, EPS, and TC&R simulators.
