Remote Diagnostics refers to ability to diagnose a subject (system, craft or person) from a distance. Instead of the subject being colocated with the person or system doing the diagnose, both can be far apart (earth-moon distance for instance), connected by wire or wireless.

When limiting to systems, a general accepted definition is: 'To Improve reliability of vital or capital-intensive installations and reduce the maintenance costs by avoiding unplanned maintenance, by monitoring the condition of the system remotely. '

Process elements for remote diagnostics:

Remotely monitor selected vital system parameters
Analysis of data to detect trends
Comparison with known behavior database data
After detected performance degradation predict the failure moment by extrapolation
Order parts and plan maintenance, to be executed when really necessary, but in time to prevent a failure or stop

Typical uses:

medical use (see Remote guidance)
Formula 1 racecars
space (Apollo project and others)
Telephone systems like a PABX
aeroplanes, like 747, Fokker, Airbus and many others.

The reasons for RD can be one of more of these aspects:

limit local personnel to a minimum (Gemini, Apollo capsules: too tight to fit all technicians)
limit workload of local personnel
limit risks (exposure to dangerous environments)
central expertise (locally solve small problems, remotely/centralized solve complex problems by experts)
efficiency: reduce travel time to get expert & system or subject together

Remote Diagnostic & Maintenance

Remote Diagnostic & Maintenance refers to both diagnoses of the fault or faults and taking corrective (maintenance) actions, like changing settings to improve performance or prevent problems like breakdown, wear & tear. RDM can replace manpower at location by experts on a central location, in order to save manpower or prevent hazardous situations (space for instance).
