• Optimizing Bandwidth Utilization in Packet Based Telemetry Systems

      Kalibjian, Jeffrey R.; Lawrence Livermore National Laboratory (International Foundation for Telemetering, 1995-11)
      A consistent theme in spacecraft telemetry system design is the desire to obtain maximum bandwidth utilization given a fixed transmission capability (usually due to cost/weight criteria). Extensions to basic packetization telemetry architectures are discussed which can facilitate a reduction in the amount of actual data telemetered, without loss of data quality. Central to the extensions are the establishment of an "intelligent" telemetry process, which can evaluate pending data to be telemetered, and act to compress, discard, or re-formulate data before actual transmission to ground stations.
