Chapter 2: HISCALE Data File Descritions and Overview


Chapter 2.2: Experiment Data Record (continued)


2.2.2 EDR Data Block Format Specifications


Data Overview.  EDRGEN accepts frame synchronized telemetry data in the Science Data Format.  EDRGEN extracts the appropriate words from the telemetry minor frame and places them into the defined locations in the data blocks of each individual science record.  Filler and spare bits in the EDR formats are binary zeroes unless otherwise noted.


Each experiment record contains standard SFDU primary and secondary headers, an ISPM unique tertiary header, and an instrument unique science data block reflecting the instrument record structure.  Each record will also contain a complete set of engineering and housekeeping for the time period covered by that record.  Figure 2.1 defines an EDR record format.  EDR tapes contain collections of these records separated by inter-record gaps.


Figure 2.1 ISPM EDR record format





The Radio Science and Gravitational Wave experimenters occasionally request engineering EDRs which contain only engineering and ground monitor records.


The following subsections define EDR processing, record build-up, and the EDR data block formats for each instrument.  The "DS#" designations are generic and represent digital science words for the particular instrument.  These designations are the same as those shown in the telemetry format diagram found in the Experiment Appendices of the ESA Functional Requirements for ISPM Data Processing ("green blocks").
