SDI-104 MTSAT HRIT Software Changes

This page lists the software changes included with each SDI-104 MTSAT HRIT version available on the McIDAS Website. Each version contains all changes in the previous versions.

Changes in Version 20100520

  • updated MTSAT server for support of MTSAT-2

Changes in Version 20080919

  • added Java-only JPEG decoding software, resulting in more stable software and reduced memory usage
  • corrected problem where subsequent event notifications (defined in the notify.list file) were skipped if the event triggered the execution of a non-existent target (e.g., a local script that does not exist)
  • added logging of event notifications in the file /data/opt/etc/notify.log (must exist and be writeable)

Changes in Version 20071219

  • improved performance with less memory usage and improved stability under heavy loads
  • made card reads more efficient by using FileInputStream with fixed-size buffer instead of more CPU intensive BufferedInputStream
  • modified ingestor stop procedure to properly stop the intermediate memory buffer
  • modified to avoid need for synchronization during JPEG decoder thread creation, and to attempt garbage collection after each image segment completes
  • added sanity-check on packet header length fields

Changes in Version 20071127

  • improved error handling
  • modified ADDE servers to support multiple bands
  • changed to write ingestor restart events to the system console
  • increased size of raw data buffer
  • added performance tuning configuration changes
  • serialized image segment processing threads, so only one is active at a time
  • changed to log processing statistics at the end of each image, instead of once per hour
  • changed to give image segment files a temporary prefix during ingest, to avoid race condition with client data access
  • changed to store satellite name in image segment files as an ancillary header if system property tag_sat_name is set to true in the ingestor configuration file

Changes in Version 20070802

  • added MANAM processing
  • added console messages for image start/end and MANAM events
  • updated ADDE server navigation handling
  • reduced CPU load
  • improved error-correction code
  • changed NH and SH filemasks in RESOLV.SRV to include FD
  • updated rc.ADDE to modify hosts.allow to allow connections by default

Changes in Version 20070123

  • initial release of SDI-104 MTSAT ingestor for use with MTSAT-1R data in the HRIT format
