ATR (Air Transport Rack) is a standard that specifies form fit and function of enclosures designed to protect
the main internal system. This military enclosure must meet EMI / EMC requirements to prevent noise
interference, provide lightning protection and be isolated from small particle contaminants. So, it can be
deployed in unmanned aerial vehicles, fighters, and helicopters. To satisfy diverse conditions, ATR chassis are
available in different sizes—1/2, 3/4 and Full ATR sizes. Based on 3/4 ATR size, 7Starlake launches a new Rugged
Airborne Mission Computer F40.

ARINC 429 is the worldwide standard for data transmission in aircraft electronics. It is adopted mostly for
commercial aircraft and transport aircraft network protocol standard. Communications, guidance, altitude,
altitude reference, flight management, and more are all needed to work together to accomplish a successful
flight. The physical connection wires are twisted pairs carrying balanced differential signaling.

The ARINC 429 unit of transmission is a fixed-length 32-bit frame, which the standard refers to as a ‘word’. The
bits within an ARINC 429 word are serially identified from Bit Number 1 to Bit Number or simply Bit 1 to Bit 32.

MIL STD 1553 is US Military Department of Defence standard that was initially published in 1973.

MIL STD 1553 is a differential serial bus. Also, it is a dual redundant data bus. Each node is connected to each
of the redundant buses. Secondly, if one should fail, communications can still continue.

There are three types of operating nodes for 1553 Bus:
