Data Transmission

The ISIS has a number of sensors positioned at strategic points throughout the vehicle.

They are located in the satellites that are connected to the SIM via the

byteflight

. All sen-

sors are scanned continuously and the data distributed to all satellites.

Diagnosis

Diagnosis of the

byteflight

is carried out using the Diagnosis Program. Since the

byteflight

is a star structure and not a continuous ring like the MOST there is a test module “Data

transmission to the satellites” that can check communication between each satellite and

the SIM module.

Any satellite that does not respond must then be checked individually using a separate Test

Module.

Repairs to the

byteflight

fiber-optic cable are not permitted. However, complete cables

between the SIM and the affected satellites may be replaced.
