Spacecraft Avionics

Tiger Innovations personnel have significant experience designing hardware and software. Our hardware designs span analog and digital designs, including processor boards, FPGA designs, analog-to-digital conversion, analog controls and power supplies. We understand the issues involved in designing electronics to operate within a space environment (e.g. conduction-cooling, vacuum compatibility, radiation damage and fault-tolerance) as well as the tradeoffs required in designing spacecraft systems. Additionally we have designed and coded flight and ground software to run on both our own as well as other designs. Tiger Innovations recently served as the lead for the architecture, design, and integration of STPSat-1's avionics systems (launched in March 2007) and is currently operating successfully. Tiger Innovations was an integral part of meeting the aggressive test schedule and ensuring STPSat-1 met all test requirements in preparation for launch.

In addition to large system design, we are also accomplished at FPGA design and small data acquisition and control applications. Some of these control applications have involved DSPs and other digital signal processing techniques, whereas others have involved microcontrollers, pulse-width modulated control, A/D and D/A conversions, and current, voltage, and temperature monitoring.

Tiger Innovations has had the rare opportunity to design several systems and subsystems from scratch, as well as integrate with existing ones. Designing systems from the ground up has allowed us to learn to see the "big picture" and to understand how design decisions affect the final implementation. Alternatively, working on projects where the objective is to fit within an existing, unchangeable system has afforded us experience at making the most of the system architecture and using it to our advantage. Drawing on our experience of approaching problems from both sides enables us to arrive at unique, system-effective solutions and to be more versatile problem-solvers.
