MICRO PULSE LIDAR NETWORK

NASA/GSFC has a requirement to upgrade an existing Micro Pulse Lidar (MPL) instrument used by the NASA Micro Pulse Lidar Network (MPLNET). NASA/GSFC intends to purchase the item from Sigma Space Corporation. Sigma Space Corporation is the sole manufacturer and seller of the MPL that can meet NASA requirements. To our knowledge, there are no other commercially available MPL products that meet current MPLNET specifications. NASA requires delivery by December 2016 to avoid project delays.
