Dr. James Carswell
Founder, President & Chief Technology Officer
Dr. James R. Carswell received the Ph.D. degree in Electrical Engineering from the University of Massachusetts-Amherst and the B.S.E.E degree from Tufts University. He is an adjunct professor at UMass. As co-founder and president of RSS, Dr. Carswell serves as the Company’s main technology visionary for providing hardware, digital processing and data management solutions for remote sensing applications. He has led the development of an FPGA-based digital receiver for the NASA High Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) that will be deployed on the NASA Global Hawk UAV. He designed the solid-state Ku/Ka-band transceiver for HIWRAP and lead the design and development of a similar transceiver in support of a ground validation Ku/Ka-band radar for the NASA GPM mission (D3R). Dr. Carswell has developed and implemented real-time inversion algorithms to derive the ocean surface wind field from measurements acquired with NOAA’s operational instrumentation and has developed real-time inversion algorithms for extracting precipitation rates and ABL winds. This work has been used to support NASA’s QuikSCAT mission. He has also led the development of an adaptable web server and processor to provide real-time and historical access to sensor data on the NOAA WP-3D aircraft and is very familiar with the aircraft and scientific data being collected by this platform. He was the principal investigator on a project with NOAA Aircraft Operations Center to develop the next generation main data system on the NOAA aircraft. This system is responsible for collecting, storing, processing and distributing all data collected on NOAA aircraft. Dr. Carswell has been designing, developing and deploying remote sensing instrumentation since 1992. His accomplishments prior to founding Remote Sensing Solutions include: leading the unmanned aerial vehicle (UAV) and hurricane remote sensing programs at the University of Massachusetts; developing the first solid-state airborne W-band cloud radar for use on UAVs; developing the first solid-state airborne W-band Cloud Radar utilizing digital pulse compression and achieving sensitivities equal to EIK amplifier based systems; developing the first dual-wavelength Doppler radar for airborne hurricane remote sensing (IWRAP); and leading the development of a wireless broadband network solution based on the 802.16 (WiMAX) draft standard.

Chief Executive Officer
Mr. Mike Fernandes holds a BSME from Northeastern University and a Certificate in Management Essentials from Wharton Business School. Prior to joining RSS, Mr. Fernandes spent his career in leadership roles at various companies designing and manufacturing elastomeric seals for various markets. During an 11 year period at Acushnet Rubber Company he helped the company grow from $40mm to $110mm while holding leadership positions in both engineering and operations. Mr. Fernandes became one the youngest Directors of Engineering in the company’s 100+ year history. He was assigned to lead all major business development including Fuel Seals, Golf Grips, and specialty wiper blades all totally over $50mm annually. He then co-founded and led an ISO9001 and TS16949 design and manufacturing company that grew sales through the development of products/processes, development of IP, building a sales network, development of a state of the art manufacturing facility, and through the acquisition of two smaller competitors.
Mr. Fernandes’ technical, business and entrepreneurial skills are being utilized by RSS to help it develop and commercialize products and services the company has spent years in research and development. Mr. Fernandes believes that game changing products and services can be developed for applications in aerospace, automotive, marine, defense, environment, and science. Since joining the company in late 2016, the company has been transformed into a commercial supplier of COTs products with product revenue growth over 700% while also maintaining R&D efforts to expand product offerings.
Principal Hardware/Software Engineer
Torry Akins received both his M.S. and B.S. degrees in Electrical Engineering from the University of Kansas.
Since joining RSS, Mr. Akins has developed a 1 GHz Direct Digital Synthesizer (DDS) module and a 3.6 GHz 12 bit data acquisition module. The DDS module supports the generation of multiple linear chirps and/or pulses. Additionally, it supports the application of arbitrary amplitude tapers to its output waveforms. The data acquisition modules can directly capture high bandwidth radar returns. These data are buffered and transferred over a high speed serial link to RSS’s digital receiver. Multiple data acquisition modules can be synchronized to capture the return from a multi-channel radar system.
Prior to joining RSS, Mr. Akins worked in the Aviation Department at Garmin International where he led the development of several of Garmin’s transponder products. Before that, he was at the University of Kansas where he worked as a staff engineer at the Center for the Remote Sensing of Ice Sheets (CReSIS). During that time, he developed the waveform generators and data acquisition systems for several airborne and ground based radar systems.
Bryan Townley received a B.S. degrees in Electrical Engineering from the University of Kansas.
Prior to joining RSS, Mr. Townley worked six years at the Center of Remote Sensing of Ice Sheets (CReSIS) where he worked as a printed circuit board (PCB) designer developing printed circuit assemblies (PCA’s) a circuit components for ground penetrating imaging radars. During that time, he developed radio frequency components that covered the HF to UHF spectrum. He also was the primary power supply designer and wiring technician on new radar builds.
When Bryan was not designing circuit boards he served as a lead field engineer with NASA’s Operation Ice Bridge polar research campaign. For more than five years he played a intricate role in preparing and integrating radar equipment to fixed wing NASA aircraft. His role did not stop there. Bryan has spent more than 2000 hours on three different NASA manned aircraft collecting snow/ice thickness data over the Arctic and Antarctic regions.
