Orbital Micro Systems (OMS) proposes to build SPECTral Radiative transfer Unified Model (SPECTRUM), a pan-spectral radiative transfer and algorithm development system. SPECTRUM fulfills a need by the Navy for a unified Radiative Transfer Model (RTM) framework from UV to radio frequencies to aid in instrument design and algorithm development. SPECTRUM will integrate existing RTM and retrieval algorithms to collectively span the desired range of frequencies. The Phase I objectives are 1) Design the SPECTRUM architecture to run multiple RTMs and algorithms. Build a rapid prototype with two RTMs. 2) Design a Spectra database of radiative spectra and other inputs required to run various RTM and algorithms. Use case to demonstrate how to use the database by changing the input spectra for one RTM to increase its frequency range. 3) Design an algorithm testbed to support the development of retrieval algorithms. Build a rapid prototype Testbed. Apply the testbed to two use cases: porting an algorithm and designing a new algorithm. OMS will write a report describing the SPECTRUM architecture and three Use Cases. OMS will produce a full Phase II development plan, a SPECTRUM prototype with two integrated RTM, a database design, and a prototype testbed.
Benefit: OMS launched its first CubeSat, Global Environmental Monitoring System (GEMS1), in July 2019. OMS will build a 40+ satellite constellation starting with the first launch of its second-generation satellite, GEMS2, in late 2023. GEMS1 had eight channels around the 118 GHz absorption band and GEMS2 has 24 channels surrounding the 118 GHz and 183 GHz bands. OMS seeks to empower humanity by managing environmental risk with real time weather and climate data products. OMS hopes to tap into a $1B per year market for complex environmental intelligence applications, such as wildfire monitoring or flood analysis. OMS will develop weather data products targeting commercial opportunities within the insurance, energy, and transportation sectors. SPECTRUM represents a component of a larger solution, rather than a stand-alone product. OMS will sell SPECTRUM as a service to the Navy, Air Force, NASA and other large organizations to aid in algorithm development. However, the real value of SPECTRUM to OMS lies in new product development. OMS wants to use SPECTRUM to help solve industry and government problems with new data products and services. OMS will use SPECTRUM to expand its data product offerings by combining data at multiple frequencies from different environmental sensors on multiple platforms.
