SKA-PST

This project implements the Pulsar Timing Signal Processor (PST) of the Square Kilometre Array (SKA). It provides the umbrella helm chart that integrates the CORE components of PST (SMRB, RECV, DSP, STAT, and SEND) with the Local Monitoring and Control (LMC) component. It also implements a number of system integration tests and provides documentation for integrating and using PST.

Current Capability

The current release of PST (ska-pst 0.6.3) implements the following capabilities:

• Data Acquisition – capture the tied-array voltages from the correlator beam former (CBF) and write them to a ring buffer in shared memory

• Voltage Recorder – record the tied-array voltages from the CBF to file

• Data Quality Statistics – compute various statistical summaries of the tied-array voltages recorded to file

• File Transfer – transfer recorded voltage files to a persistent volume shared with the Science Data Processor (SDP) and make them available in the Data Product Dashboard
