Project Examples: Certified Products by the Team
Our Build-to-Spec capability is best demonstrated through our team's successful track record of developing and certifying real-world avionics products.
FAA-Certified Global Navigation Receiver (Aviation-grade)
Description: The team was responsible for the full-lifecycle product development, from design to FAA certification and manufacturing. Over 10,000 units of this product have been delivered.
Implementation: The project involved full-lifecycle product development, including Single Board Computer, RF/Analog hardware, Digital hardware (Processor & FPGA), and Power Supply components. The software contained > 50K SLOC, and the FPGA program had > 5K SLOC.
Standards:
FAA-Certified Flight Awareness Broadcast System
Description: This was a Build-to-Spec effort to design, develop, and FAA-certify an ADS-B transponder to detect air traffic up to 300 KM.
Implementation: The team handled full-lifecycle product development, including Single Board Computer, RF/Analog hardware, Digital hardware (Processor & FPGA), and a Power Supply with hold-up and EMI/EMC circuits. The software was > 100K SLOC, and the FPGA program was > 10K SLOC.
Standards:
FAA-Certified Remote Data concentrator unit(RDCU)
Description: The team designed, developed, and certified an Remote Data concentrator unit(RDCU) that acts as an interface between avionics systems with incompatible interfaces. The unit is used in retrofit solutions.
Implementation: The design was based on the Single Board Computer.
Standards:
Certified by the FAA and qualified to meet DO-160G standards.
