About This Item

 

Full Description

This document defines adaptations and conversions of the Consultative Committee for Space Data Systems (CCSDS) standard Space Link Extension (SLE) Return All Frames (RAF) telemetry data transfer service. The CCSDS SLE transfer services do not support some legacy command and telemetry data flows that must be accommodated by US civil, military, and commercial space element tracking, telemetry, and control networks to allow interoperability in support of US Government space operations. Adaptations of RAF by the user and conversions of RAF by the provider provide standardized time-correlated telemetry and command echo services which are not otherwise provided by CCSDS SLE transfer services. Time-correlated telemetry service supports space elements which use unframed bit streams or bit streams without provider-side frame synchronization. Command echo service supports systems which require an independent check of provider RF equipment.
