DCART
5:17. Main functions of DCART software are:
• Support of Science Operations
o Program design
o Schedule design
o Daily operations design (scheduling rules)
o Campaign events design
• Real-time Data Processing and Visualization
o Science data
o Housekeeping data
• Manual Commanding
o Start and stop
o Switching operating states
5:18. Figure 5-4 shows the block diagram of DCART software. DCART handles two distinct data streams,
telemetry (incoming data from CONTROL Platform) and commanding (outgoing data to Control Platform).
Correspondingly, the telemetry part of interface has the Parser thread responsible for syntactic analysis of in-
coming packets from the Network Driver, extracting their payload section, and referring it to the queue of the
Payload Dispatcher. The commanding part of interface has the Framer thread responsible for proper packaging
of the command payloads from its queue and delivering them to Control Platform via the Network Driver.
