About Yamcs: SLE PluginΒΆ

This plugin extends Yamcs with links to connect via the CCSDS SLE (Space Link Extension) protocol to SLE-enabled ground stations. These are typically the ground stations of national space agencies.

The supported services are:

The services are supported by the SLE Internet Protocol for transfer services (ISP1) specified in CCSDS 913.1-B-2.

The RAF and RCF services are further divided into:

  • online timely: used for retrieval of frames with a guaranteed timeliness of data - if the receiver of the data cannot process the data fast enough (or the network link towards the receiver is too slow), the provider will drop data.

  • online complete: used for retrieval of frames when the receiver wants to receive complete data at the expense of timeliness. The provider will buffer the data if the receiver is too slow.

  • offline: used for retrieval of frames stored at the provider (ground station).
