MH-370 Communication System discusses the communication systems onboard Malaysia Airlines Flight 370 that disappeared in 2014 - the Aircraft Communication Addressing and Reporting System (ACARS) and Satellite Communication System (SATCOM). It notes the last transmissions were at 1:08 MYT from ACARS and 8:11 MYT from SATCOM. The document suggests outdated technology, manual interference with systems, and wide gaps between transmissions hindered the investigation, and that automated dependent surveillance and satellite ping location updates could have helped determine what happened.
