Easy Installation. High Performance.
Designed for efficiency from the inside out, the SkyLog-MDAU features a miniature, hermetically sealed enclosure ideal for rugged commercial aviation and defense environments.
Installation is quick and secure, with captive fasteners that prevent dropped hardware and eliminate the risk of FOD during integration.
Powered by FPGA-based processing and high-speed analog front ends, the SkyLog-MDAU supports simultaneous acquisition of digital (e.g. ARINC-429) and analog (e.g. Synchro) inputs using the same pins across configurations streamlining setup and reducing hardware variation.
The primary output utilizes a high-speed ARINC-429 bus, ensuring efficient data throughput and seamless system compatibility.
