Summary of Release 15 GES Upgrade
  • Release 15 (R15) Most recent system software
    upgrade for ground earth stations interfacing
    with Inmarsat Classic Aero I-3 satellites
  • Purpose of upgrade
  • To improve GES data link delivery capability and
    aircraft log-on management subsystems
  • To enhance GES traffic handling and monitoring
    subsystems

Summary of Observed Performance Following R15
Upgrade
  • Eik GES
  • Improvement in the ACTP was not observed
    immediately following the R15 upgrade, but the
    most recent data does show a noticeable
    improvement in performance for CPDLC transactions
  • ADS-C downlink latency performance is observed to
    have degraded in the period immediately following
    the upgrade as well as in the most recent period

Summary of Observed Performance Following R15
Upgrade
  • Santa Paula GES
  • Improvement can be observed for both the ACTP for
    CPDLC transactions and ADS-C downlink latency
    performance for ADS-C downlink messages
  • Improvement shown to be stable between the period
    immediately following the upgrade and the most
    recent period of observation for both performance
    measures

Summary of Observed Performance Following R15
Upgrade
  • Aussaguel GES
  • Improvement can be observed for both the ACTP for
    CPDLC transactions and ADS-C downlink latency
    performance for ADS-C downlink messages
  • Continued improvement shown between the period
    immediately following the upgrade and the most
    recent period of observation for both performance
    measures

Summary of Observed Performance Following R15
Upgrade
  • Perth GES
  • Slight improvement can be observed for both the
    ACTP for CPDLC transactions and ADS-C downlink
    latency performance for ADS-C downlink messages
  • Continued improvement shown between the period
    immediately following the upgrade and the most
    recent period of observation for ACTP
  • Improvement shown to be stable between the period
    immediately following the upgrade and the most
    recent period of observation for the ADS-C
    downlink latency performance

28
Conclusions
  • Overall improvement in data link performance at
    GES level following R15 upgrade
  • Improvement most noticeable at the Santa Paula
    and Aussaguel GES
  • In general - upgrade appears to have had more of
    an impact on the ACTP than on the ADS-C downlink
    latency performance
