At NASA Goddard Space Flight Center (GSFC), we have been developing spaceborne lidar instruments for space sciences. We have successfully flown several missions in the past based on mature diode pumped solid-state laser transmitters. In recent years we have been developing advanced laser technologies for applications such as laser spectroscopy, laser communications, and interferometry. In this paper, we will discuss recent experimental progress on these systems and instrument prototypes for ongoing development efforts.

“…So far, two spaceborne lidar could provide scientific data, include Ice, Cloud, and Land Elevation Satellite (ICESat-1) launched by the NASA in 2003, , Hu, 2019and Lefsky, 2010, and Ice, Cloud, and Land Elevation Satellite (ICESat-2) (Neuenschwander, 2019) successfully launched in 2018, respectively. ICESat-2 is a continuation of the ICESat-1 scientific mission, planning to provide scientific and accurate photon data for global forest biomass (Sawruk, 2018 andMarkus, 2017). However, because the ICESat-2 system has the characteristic of photon-counting, the signal photons emitted and received are weak signal photons, which are greatly affected by background noise (solar background noise, system dark noise, et al).…”

Abstract. As a continuation of Ice, Cloud, and Land Elevation Satellite-1 (ICESat-1)/Geoscience Laser Altimeter System (GLAS), the Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) , which is equipped with the Advanced Topographic Laser Altimeter (ATLAS) system, was successfully launched in 2018. Since ICESat-1/GLAS has facilitated scientific results in the field of forest structure parameter estimation, how to use the ICESat-2/ATLAS photon cloud data to estimate forest structure parameters has become a hotspot in the field of spaceborne photon data application. However, due to the weak photon characteristics of the ICESat-2/ATLAS system, the system is extremely susceptible to noise, which poses a challenge for its subsequent accurate estimation of forest structural parameters. Aiming to filter out the noise photons, the paper introduces the advantages of the spaceborne lidar system ICESat-2/ATLAS than ICESat-1/GLAS. The paper summarizes the research of the simulated photon-counting lidar (PCL) noise filtering algorithm and noise filtering on spaceborne.
