OMS Data Receipt (ODR) Pipeline Project
Contents
ODR Pipeline Overview
The OMS system at STScI utilizes Engineering Telemetry Subsets to produce its
output products. These Subsets are currently generated by the AEDP system at
GSFC and transferred to STScI. With the impending termination of AEDP in the
Fall of 1998, the OMS system itself will assume responsibility for Subset
generation. Upon AEDP termination, a new system, i.e., the CCS system at GSFC
will provide OMS with merged, all-points Engineering Telemetry in CCS Front-End
Processor Output Format (FOF format). It is from this FOF format data that the
OMS system will generate Engineering Telemetry Subsets.
To obtain FOF format data from CCS and to generate Subsets from the data, a new
OMS pipeline will be used; i.e., The OMS Data Receipt (ODR) Pipeline. This
new pipeline is composed of five processes. Short descriptions of the
processes are provided below. Details of each process can be examined in the
ODR Pipeline Requirements Document and in the Design Document for each of the
respective processes.
- PNMFOF - determines what CCS FOF format Engineering Telemetry is ready to
be copied from the CCS system to the OMS system and generates FTP
scripts used to transfer the data
- FTPFOF - uses FTP scripts generated by the PNMFOF process to transfer
compressed FOF data from the CCS system to the OMS system
- ZIPFOF - decompress (GZIP) FOF data that was transferred from the CCS
system to the OMS system
- CVTFOF - converts FOF data transferred from the CCS system to the OMS
system into Engineering Telemetry Subsets
- CLNFOF - deletes PNM Files, PNM Scripts, FOF Files, and FOF scripts after
Engineering Telemetry Subsets have been successfully producedby
the CVTFOF process
In conjunction with the new OMS Data Receipt Pipeline, a new OMS pipeline
process (SUBPOL) will be added to serve as the interface between the two
pipelines. A short description of SUBPOL follows:
- SUBPOL - polls the OMS input data directory for pairs of Engineering
Telemetry Subset/Error Files produced by the Data Receipt Pipeline
CVTFOF process and creates Subset File OSFs which trigger execution
of the OMS Pipeline OMSTLM process
For more information on the the SUBPOL process, reference the
ODR Pipeline Requirements Document.
