Breaking changes

  • Regarding nmts.ek.v1alpha.physical.Modulator
    • the code has been moved from ek/physical/modulation.proto to ek/physical/modem.proto
    • field adaptive_coding_and_modulation_to_channels has been removed
    • field adaptive_coding_and_modulation_for_channel_bandwidths has been added with a different structure:
      • Previously, the AdaptiveCodingAndModulation message stored a list of ModcodToDataRates, where each ModcodToDataRate stored a oneof of thresholds of received signal quality. This structure allowed the definition of thresholds through multiple metrics within the same AdaptiveCodingAndModulation message (i.e. as both power at receiver output and C/(N+I)), and this should not be allowed.
      • Now, the AdaptiveCodingAndModulationForChannelBandwidth message stores a oneof of lists of thresholds of received signal quality, so all elements must use the same metric. 
      • Previously, AdaptiveCodingAndModulationToChannels defined an adaptive_coding_and_modulation and all of the channels to which this ACM configuration applied. All channels had to be of the same bandwidth because the data rates in the AdaptiveCodingAndModulation message depend on the channel bandwidth, but this was not clear from the structure of the proto.
      • Now, this message has been renamed to AdaptiveCodingAndModulationForChannelBandwidth, and it stores a single field for the channel bandwidth and a separate list of center frequencies.
    • Removed min_received_signal_power_dbw as an option for defining MODCOD thresholds. Carrier to noise-plus-interference should be used instead.
  • Regarding nmts.ek.v1alpha.physical.Demodulator
    • the code has been moved from ek/physical/modulation.proto to ek/physical/modem.proto
    • field adaptive_coding_and_modulation_to_channels has been removed
    • field adaptive_coding_and_modulation_for_channel_bandwidths has been added with a different structure (see Modulator)
  • Regarding nmts.v1alpha.ek.service.Uni
    • has been renamed nmts.v1alpha.ek.logical.Uni (logical instead of service)
  • In nmts.v1alpha.ek.logical.LogicalPacketLink
    • field properties has been removed
    • field max_data_rate_bps has been added (before was nested inside properties)
  • In nmts.v1alpha.types.geophys.CcsdsOrbitEphemerisMessage
    • field file has been renamed to file_contents
