====Telemetry processing====

Control centers use telemetry to determine the status of a spacecraft and its systems.<ref name=ley/>{{rp|485}} Housekeeping, diagnostic, science, and other types of telemetry may be carried on separate [[virtual circuit|virtual channel]]s. Flight control software performs the initial processing of received telemetry, including:

# Separation and distribution of [[virtual circuit|virtual channel]]schannels<ref name=ley/>{{rp|393}}

# [[Connection-oriented communication|Time-ordering and gap-checking]] of received [[Frame (networking)|frame]]s (gaps may be filled by commanding a retransmission)

# [[Commutation (telemetry)|Decommutation]] of parameter values,<ref name=JPL_10/> and association of these values with parameter names called [[mnemonic]]s
