Subscription Points

Mid CBF MCS subscribes to the following subscriptions points:

DelayModel

As per the TMC-CSP Mid ICD, CSP requires Geometric delay as a fifth-order polynomial per receptor per Frequency Slice per polarization every 10 seconds. Regular updates during the scan are required. Keeping these requirements in mind, Geometric delay calculation is implemented in the TMC CSP Subarray Leaf Node. It should be delivered via the publish-subscribe mechanism, published on the “DelayModel” attribute of the CSP Subarray leaf node.
