1 Notes for Signalling Unit Log for (9M-MRO) Flight MH370 This set of notes and accompanying tables is intended to provide a readable summary of the data communication logs from the Inmarsat satellite system provided to the authorities in connection with the ongoing investigation and search and rescue activities relating to MH370. All times are in UTC The table below is a readable form of the logfile recorded at the ground earth station for the communications with the terminal on MH370 from 16:00 to the last Handshake Request (Log On Interrogation) attempt at 01:16 UTC Some columns which contain no material information have been removed from the tables below for readability An example of a complete message for a single log entry: Field Headings: Time, AES ID, DP AES Owner,,,, Bearer,, Type, Superframe Number, Frame Number, Slot Number, SU Number,, Code, SU Contents, Q Number, Reference Number, Ack Control, SDM Figure, CRC Correct, Missed T-, Broadcast, Rx Power (dbm), C/No, (Hz), Estimated BER, Example message: 7/03/ :42:04.408, ,SITADP (3047),IOR-R ED,IOR,305,Rx Primary,4,R- RX,12184,,5,,0x62 - Acknowledge User Data (Rchannel),62,1F D F C5 7A 4E F 89,D,0,E,S31,Yes,No,No,-57.29,40.09,146,0,14920 Understanding the () values: The round trip time for a message is a combination of: 1. Time from the ground station satellite aircraft satellite ї ŐƌŽƵŶĚƐƚĂƟŽŶ 2. Processing time within the ground station, satellite and aircraft terminal, which are constant The is a value (in microseconds) relative to a terminal at a nominal fixed location. Only R- messages are used. The therefore allows the determination of the distance between the satellite and the aircraft. It does not provide the actual aircraft location 1
2 Understanding the () values: The transmission signal path from the aircraft has two components affected by Doppler shift; between the satellite and aircraft, and between the satellite and ground station The following need to be considered when computing the expected frequency offset: o Inmarsat Classic Aero mobile terminals are designed to correct for aircraft Doppler effects on their transmit signals. The terminal type used on MH370 assumes a stationary satellite at a fixed orbital position o An individual aircraft terminal will have a fixed frequency bias o Satellite, terminal and ground station oscillator stability o The correction applied by the Automatic Control (AFC) system in the ground station partially compensates for the satellite to ground station Doppler 2
