About this file
This Statement of Work (SOW) details NASA Goddard Space Flight Center's requirement for a Plymouth Marine Laboratory (PML) Solar-Tracking Radiometry (So-Rad) control system. The system must provide autonomous collection of full-spectrum light intensity measurements using TriOS RAMSES radiometers, enabling continuous measurements of light intensity from water, sky, and sun on a moving ship or fixed platform. The control system specification includes comprehensive hardware requirements such as a Raspberry Pi 3 Model B+, motor unit, RTK GPS, Ethernet port, power supply, and sensor interfaces, as well as firmware capabilities for data logging, data acquisition, HDF file generation, and system configuration.
The SOW outlines a 4-5 month performance period at the Ocean Ecology Laboratory in Goddard Space Flight Center, with a detailed procurement table indicating specific system components and firmware upgrade requirements. The system is intended to validate ocean color measurements for NASA's Plankton, Atmosphere, Cloud, ocean Ecosystem (PACE) and other satellite radiance measurements. The procurement includes construction, programming, and testing of the So-Rad control system, with specific firmware upgrades to improve system performance, and includes a one-year warranty. The commodity code for the primary item is 854900000, and the system involves day rate engineering and development work.

STATEMENT OF WORK
1. Objective/Requirements
Goddard Space Flight Center requires the purchase of Plymouth Marine Laboratory (PML) Solar-Tracking Radiometry (So-Rad) control system hardware and firmware. This integrated hardware and firmware system will enable autonomous collection of full-spectrum light intensity (radiometric measurements) using NASA-owned commercial off-the-shelf instruments (specifically, TriOS RAMSES radiometers). The So-Rad system with integrated TriOS RAMSES sensors will permit continuous and autonomous measurements of light intensity of the water, sky and sun from a moving ship or fixed platform/tower enabling computation of complete light spectrum ocean water-leaving radiances, which are the fundamental ocean color measurements required to validate ocean color measurements.
2. Characteristics, Scope, and Specs
The So-Rad control system must provide the following capabilities:
Autonomous control to rotate the system with installed TriOS Ramses to ensure proper views of the ocean, sun and sky by tracking ship heading, GPS, and sun components and country of origin):
Control (includes Raspberry Pi 3 Model B+) plus motor unit Bracket Shipping case 110-240 VAC power supply
RTK GPS
Ethernet port + connector 5 m cabling to motoer Plastic enclosure Sensor interfaces/connectors for each of the 3 sensors 3 TriOS G1 bulgin connectors Test lead cable with plug
Firmware Capability of data logging from the So-
GPS and sun location.
Capability of data acquisition from the TriOS RAMSES water, sky and sun-viewing radiometers.
Upgrades from current firmware
Configurable relative azimuth target and testing Export from local format to HDF format Automate scheduling of HDF file generation Additional system log for configuration changes and accessibility to operator Min/Max sensor elative azimuth condition Control upgrades via web interface
Improve system speed by moving non-sampling firmware processes to the background
Labor to construct, program and test the So-Rad control system Shipping One-year warranty
3. Place of Performance
Ocean Ecology Laboratory NASA Goddard Space Flight Center Bldg 22, Rm C135 8800 Greenbelt Rd Greenbelt, MD 20771
4. Period of Performance
