STATEMENT OF NEED

Requiring Office Name: National Severe Storms Laboratory

PR#: NRMAG0002300201

1. Background and Purpose To build additional balloon borne microphysics instruments (known as the PASIV) for use by NSSL during the Lake Effect Electrification (LEE) project this winter. The PASIV’s require a specific 4k resolution camera in order to achieve greater detection sensitivity and finer resolution for detected particles. A specific camera that meets the needs of the PASIV has previously been identified and is currently in use. Additionally, the 4k camera requires an onboard computer with PCIe connections to connect to and run the data acquisition. This computer must be lower power and lightweight as well as a small form factor given the weight requirements of the unmanned balloon. A suitable computer system is available from the camera manufacturer directly designed to work with this camera and is the best option available to meet all requirements. As the current PASIV’s must be able to interface with existing equipment and software, identical hardware is required.

2. Scope and Objectives A total of 5 complete systems (e.g., 5 cameras, 5 carrier boards, and 5 ribbon cables) are required for purchase, along with associated accessories needed to connect the camera system to the carrier board and power each unit.

3. Product Specifications Camera system 4k (minimum 4000 x 3000 pixels) resolution CMOS Global shutter Minimum 24 fps at 4k resolution Weight < 50 grams Power < 5 watts Small form factor camera (dimensions < 50mm on a side) Power cable

Computer/Carrier board system Jetson TX2 embedded controller carrier board with PCIe, USB, and HDMI connectors M.2 interface for onboard storage Power supply for unit, <60W Heatsink with fan for the carrier board

Additional needed Accessories 0.1m flat ribbon PCIe, Gen 2 x2 cable.

4. Price Consideration:

Price by line item. Shipping must be listed separately, if applicable.

New items only, no refurbishments accepted.

5. Requested Delivery:

2-3 weeks after receipt of award, preferred by March 6, 2023.
