Steve Arroyo

Director of Engineering

Steve Arroyo is the Director of Engineering at i7 Engineering and possesses a long history of electrical engineering ranging from working on Viking 1 and 2 in 1974 to the Red Bull Stratos project in 2012. The Red Bull Stratos project was a program designed to transport skydiver Felix Baumgartner to the edge of space, to become the first skydiver to break the speed of sound while in free-fall from an extreme altitude, which he accomplished October 14th, 2012 falling at over 843.5 mph from 127,852ft.

Steve started his career at JPL in 1974 developing an Atmospheric Orbital Infrared Laser Interferometer for the High Altitude Balloon Science ATMOS program which included design of a gimbaled high-resolution Infrared Sun-tracker, a prototype Lossless Video Image Compression Processor, a Telemetry Stream Synchronizer and Discrete Digital Signal Processor for the Viking Mars Program. Other designs included a Solar Cell Array Dynamic Impedance Power Trans-match (MPPT), High efficiency Switch-mode Power Converters and Inverters, an Electrical Hybrid Vehicle Chopped H-Bridge PWM Motor Driver Controller and Hydrogen Ion-Exchange Fuel Cell. He was also involved with the development of a Very Long Base Radio Interferometer and Ground Based Telemetry Tracking System for the Deep Space Network.

During the 1980's, Steve worked on many programs ranging from the development of an ABM-MKV-L Feasibility Concept and preliminary design of a high speed Divert and Attitude Thruster Control System for a proposed spaced-based Multiple Warhead Missile Interceptor for Lockheed Martin, to a SONAR Tracking System for NAVAL ASW applications, specifically the transmit and receive sections for a NT-029 Transponder/Responder Shipset and Distress Beacon.

In the 90's, Steve worked for such companies as Hughes Aircraft and B/E Aerospace where he developed a (512x512) Crosspoint Matrix Audio/Video Electronic Switching Unit or Multi-Stage Switch used for an Advanced Passenger Airline In-Flight Multimedia Digital Distribution System, for L3 Communications developed an Underwater Communications Shipset and Sonar Tracking System referred to as (HELRAS) used for NAVAL ASW and Reconnaissance applications, a Helicopter Blade tracking notch filter, Improved the Sonar Guidance system for an AUV/LWT Torpedo that is used for Electronic Mine Demolitions, and much more.

In the 2000's, Steve worked on the Electronic System Analysis and Hardening of the RAH-66, Comanche Attack Helicopter Flight Control Systems, an SLS SONAR Guidance System for an Unmanned Underwater Vehicle (UUV), designed a Micro-miniature, Ultra-Low Power Battery operated NFC Digital PLL AM/FM Transceiver for use in a (Class-III) Implantable Medical Devices, to working on the Boeing B787 Aircraft Avionics and Power Breaking Control Systems.

In 2004, he went back to work at JPL working as a senior electrical engineer on the Power Avionic Systems for the Mars Science Laboratory mission which included development of Solar Cell Array Switching, Maximum Power Point Tracking, and Power Bus Shunt regulation of RTG’s, Thermal Pyro-Cell and Lithium-Ion Rechargeable Batteries. He developed three Spacecraft Power Box assemblies for the extreme harsh environment of Deep Space. The Cruise, Descent and Rover stages referred to as the CPA, DPA and RPA respectively, each containing four, high reliability Rad-Hard Card (Slice) sub-assemblies. He performed worst-case electronic circuit Failure and Parts Stress Analysis; FMECA and SEEU using OrCAD-PSpice. The fault tolerant designs included multi-path redundancy and (N+1) fault containment, majority vote circuitry; Arm-Enable Series/Parallel MOSFET and Deadface Relay Switching for Solar Array and Divert and Attitude Control System Thruster inhibit interlocks, Solid/Liquid Propellant Pyro-Initiator firing circuits including complex Spacecraft electrical wiring and Power Distribution.
