The Geostationary Lightning Mapper (GLM) Instrument Engineering Telemetry Data file contains data used to monitor and evaluate the health and performance of the GLM. This data is transmitted to the ground in raw digital counts, and subsequently converted into physical units by the ground system. Some of the data pertains to the temperature of components of the GLM. This includes temperatures for the CCD pedestal, focal plane array, and filtering temperatures. Other telemetry includes the number of events rejected by instrument on-board processing filters and background image count statistics.
The GLM Background Image Data file contains the average background value in digital counts for pixels in the instrument’s CCD. The averaging is performed by the instrument prior to downlink. This data is used to support the generation of GLM Level 1b products.

Processing Steps
  • Geostationary Lightning Mapper (GLM) front-end processing starts on the spacecraft where space packets are multiplexed placing multiple packets in each transfer frame. Forward error correction (FEC) coding (Low-Density Parity Check - LDPC) occurs and the packets are downlinked. The data is received, forward error correction decode is performed. In the event of an uncorrectable error the transfer frame is discarded. Error-free space packets are then extracted from the transfer frames. GLM science data arrives at the ground system from the spacecraft in a compressed format. The data is decompressed then packaged for delivery to external interfaces.
