As some of the systems are mutually exclusive due to space and weight limitations, certain combinations may not be feasible. System reconfigurations after a program has started is discouraged. If changes are essential, the user is expected to bear all costs, including labor and materials. Field installations and reconfigurations are normally not permitted due to engineering and safety considerations. Users are encouraged to become familiar with the many possible configurations of the MARS system prior to the commencement of the project.
Data processing is the responsibility of the user.
Area limited to NOAA GOES satellite coverage. The equipment must, however, conform to various engineering and airworthiness standards. Early definition of the system is strongly encouraged to ensure a timely installation. Systems and instrumentation will not be considered for installations without proper documentation. User is expected to bear all costs associated with any special installation efforts.
