Government Resource for Algorithm Verification, Independent Test, and Evaluation (GRAVITE) system is a National Oceanic and Atmospheric Administration (NOAA) system, developed and deployed by Joint Polar Satellite System (JPSS) Ground Project to support Calibration and Validation (Cal/Val), Data Quality Monitoring, and Algorithm Investigation, Tuning and Integration. GRAVITE enables novice and expert users to discover and obtain data easily by using standard protocols.

The Planner is a component of the GRAVITE version 3.0 (GV3.0) system. It determines if a Product Generation Executable (PGE) is ready to run. PGE is comprised of one or more scripts that can be run automatically. The Planner identifies whether or not all the necessary input files are available to execute a particular instance of PGE by interfacing with the GV3.0 database. Once input files are available, it stages them for a PGE execution. The Planner interacts with various GV3.0 components and facilitates standardized PGE executions. It consists of the interface to the GV3.0 database, archive, and Apache OODT (Object Oriented Data Technology) workflow.
