Housekeeping Application

The Housekeeping (HK) Application is used for building and sending combined telemetry messages (from individual system applications) to the software bus for routing. Combining messages is performed in order to minimize downlink telemetry bandwidth. Combining certain data from multiple messages into one message eliminates the message headers that would be required if each message was sent individually. Combined messages are also useful for organizing certain types of data. This application may be used for data types other than housekeeping telemetry. HK provides the capability to generate multiple combined packets (a.k.a. output packets) so that data can be sent at different rates (e.g. a fast, medium and slow packet).
