BS ISO 20207:2015 proposes advanced modulation techniques (QPSK,
8PSK, 16APSK, and 32APSK) and a wide range of coding rates (from 1/4 to 9/10) with
near-Shannon coding schemes (LDPC codes). This high number of modulation and coding
schemes allows a wide range of possibilities to satisfy specific mission constraints.Moreover, to maximize the telemetry system throughput, it appears possible to adapt the
transmitted waveform (and the useful data rate) to the variable conditions of the link. The
DVB-S2 standard can actually implement Variable Coding and Modulation (VCM) mode,
which adapts the transmission scheme to the channel conditions following a predetermined
schedule (for example, following a dynamic link budget). When a channel is available to
provide feedback (e.g., via a telecommand link), the transmission scheme can be dynamically
adjusted using the Adaptive Coding and Modulation (ACM) mode.The use of the DVB-S2 standard for telemetry makes possible the use of generic Very High
Scale Integrated Circuits (VHSIC) Hardware Description Language (VHDL) Intellectual
Property (IP) modules for developments. The use of a widely implemented standard
simplifies finding transmitting or receiving equipment to check compatibility. Finally, for the
ground part, some telecom DVB-S2 receivers or Application Specific Integrated Circuits
(ASICs) developed for the telecom market could be reused.This Recommended Standard is an adaptation profile describing how to use the DVB-S2
standard to transmit CCSDS Transfer Frames for telemetry purpose. The interface between
CCSDS and DVB-S2 is based on the Attached Synchronization Marker (ASM) and Channel
Access Data Unit (CADU) already introduced in reference [2].Cross References:CCSDS 131.0-B-2CCSDS 132.0-B-1CCSDS 732.0-B-2ISO/IEC 7498-1:1994ISO/IEC 10731:1994All current amendments available at time of purchase are included with the purchase of this document.
