MODAPS PCR 06-003

PCR Number 06-003
Date 2006-02-16
Initiator James Kuyper
Abstract Several minor updates to PGE01.
Problem Statement Portability, validate orbit #, wait for eph/att files, EV start time fill values, frame counts, leap second.
Description of Change This PCR documents many miscellaneous changes which were implemented in collection 5 under the mistaken assumption that they were too minor to need a PCR. The changes include
- Changed code changes for Linux portability and compliance with C standard.
- Changed production rules to allow either 5-min or 2-hour L0 datasets to be used as inputs.
- Changed to validate ephemeris file OrbitNumber value, by checking whether it is consistent with OrbitDescendTime.
- Corrected LoaderModule to wait for second ancillary file of each type, unless forced by operators to go ahead without it.
- Corrected to check whether Earth View start time is a fill value, and if so, set all affected output fields in Geolocation product to documented fill values.
- Corrected upper limit on valid frame counts from 1400 to 1354.
- Changed to define a granule length as 5 minutes, rather than 300 seconds, allowing the creation of 5-minute granules containing 301 seconds of data, when one of those seconds is a leap-second.
