Global Ecosystem Dynamics Investigation (GEDI) System
High resolution laser ranging of Earth’s topography from the International Space Station (ISS).
A "GEDI System Level Optical Model" refers to a computer simulation that replicates the entire optical system of the Global Ecosystem Dynamics Investigation (GEDI) instrument, a lidar sensor mounted on the International Space Station, allowing scientists to precisely model how laser pulses are transmitted, reflected off the Earth's surface, and collected by the telescope, providing detailed information about the 3D structure of vegetation and topography across the globe.
GEDI has the highest resolution and densest sampling of any lidar ever put in orbit. This has required a number of innovative technologies to be developed at NASA Goddard Space Flight Center.

Optical Networking Technology
The Elastic Optical Network (EON) is a network architecture designed to accommodate the increasing demand for flexibility in optical network resource distribution. It enables flexible bandwidth allocation to support different transmission systems, such as coding rates, transponder types, modulation styles, and orthogonal frequency division multiplexing. However, this flexibility poses challenges in the distribution of resources, including difficulties in network re-optimization, spectrum fragmentation, and amplifier power settings. Hence, it is crucial to closely integrate the control elements (controllers and orchestrators) and optical monitors at the hardware level to ensure efficient and effective operation.
