DSN Monitor Data Reader is a computer program that, as its name suggests, reads file of monitor data from the Deep Space Network (DSN). The monitor data constitute information on the status and performance of tracking, telemetry, command, and pointing equipment at the DSN antennas. The DSN has recently introduced a new, more advanced monitor data format, denoted 0158-Mon, that is based on the standard formatted data unit (SFDU) and compressed header data objects (CHDO) of the Consultative Committee for Space Data Systems (CCSDS). The 0158-Mon data format is a very flexible generic format that provides for specific variable-length formats and for self-identifying parameters that obviate the proprietary NASA Communications (NASCOM) bit-packed formats of the past. The monitor data SFDUs are also encapsulated in Standard DSN Blocks and routed to DSN customers for processing at their local mission control centers. This program helps a DSN customer to read and parse the monitor data to assess the statuses of the DSN stations in support of spacecraft flight operations.

Overview
The document outlines the DSN Monitor Data Reader, a software program developed by Katherine Levister and May Tran at NASA's Jet Propulsion Laboratory (JPL). This program is designed to read and interpret monitor data from the Deep Space Network (DSN), which provides critical information regarding the status and performance of tracking, telemetry, command, and pointing equipment at DSN antennas.
A key feature of this software is its ability to handle the new 0158-Mon monitor data format, which is based on the Consultative Committee for Space Data Systems (CCSDS) Standard Formatted Data Unit (SFDU) and Compressed Header Data Objects (CHDO). This format is notable for its flexibility, allowing for variable-length data and self-identifying parameters, which eliminate the need for the older proprietary NASCOM bit-packed formats. The monitor data SFDUs are encapsulated in Standard DSN Blocks and routed to customers for processing at their respective mission control centers.
The DSN Monitor Data Reader is essential for users who need to process this more complex data format, enabling them to assess the status of DSN stations effectively in support of spacecraft flight operations. The software is unique in its capability to process this new type of monitor data, making it a vital tool for mission control teams.
