Description
What is MESSIR-SAT?
MESSIR-SAT is a system (hardware + software) able to acquire, process, store and display satellite imagery.
MESSIR-SAT can process METEOSAT, as well as MTSAT, GOES, INSAT satellites images.
MESSIR-SAT can be delivered as a standalone “all-in-one” workstation able to perform all functions of acquisition, processing and display.
MESSIR-SAT can also be delivered as a pre-processing MESSIR-SAT server, acquiring and dispatching the satellite data to MESSIR-SAT Workstations and/or MESSIR-VISION Forecaster Workstations.
MESSIR-SAT Main Functions
MESSIR-SAT offers a complete set of functions to take full advantage of the volume of satellite imagery now available:
- Imagery acquisition, either from a parabolic antenna or from a FTP server
- Acquisition of other data flow, as “MDD”
- Storage in database
- Display and animation of satellite imagery, integration with other data types
- Production of images for end-users
- Dissemination to Web servers, other workstations, servers….
