ATR 1/2 Short Air-Borne Mission GPU Computer
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.F20G is an Air-Borne Mission GPU Computer that was designed to meet ATR 1/2 short size. F20G is built to withstand harsh environment by comply with MIL-STD 810 to sustain 75G shock and 10G vibration.
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:
F20 is designed to meet strict SWaP requirements and to withstand harsh environments, including extreme temperature, shock/vibration, sand/dust, and salt/fog. With ruggedized design and high functionality, the IP65 and MIL-STD resistance F20 is the ideal tactical vehicle on the battlefield.
