title GLAS/ICESat L1A Global Laser Pointing Data (HDF5)
comment Data granules contain approximately 190 minutes (2 orbits) of data and will include data from the laser reference system, the instrument star tracker, the gyro, the spacecraft star trackers, and the attitude control system.
summary GLAH04 data were used to compute the precise pointing for the GLAS laser beam. The data consist of the LPA (Laser Profiling Array) data, the PRAP (Position Rate and Attitude Packet) data, the LRS and IST data time aligned with laser shots and the BST (Ball Star Tracker) and the ACS (Attitude Control System) data that are not time aligned to the LPA. Each GLAH04 file was created from equivalent GLA04 binary formatted files. The provenance metadata shows the history that created the GLA04.

SuggestedUsage GLAH04 data were used to compute the precise pointing for the GLAS laser beam. The data consist of the LPA (Laser Profiling Array) data, the PRAP (Position Rate and Attitude Packet) data, the LRS and IST data time aligned with laser shots and the BST (Ball Star Tracker) and the ACS (Attitude Control System) data that are not time aligned to the LPA. Each GLAH04 file was created from equivalent GLA04 binary formatted files. The provenance metadata shows the history that created the GLA04.
