# MH370 Inmarsat Satellite Data Logs
|
14 |
+
|
15 |
+
## Overview
|
16 |
+
|
17 |
+
This dataset contains the data communication logs from the Inmarsat satellite system related to Malaysia Airlines Flight MH370 (9M-MRO). The data was provided to the authorities to assist in the ongoing investigation and search efforts for the missing aircraft.
|
18 |
+
|
19 |
+
## Dataset Contents
|
20 |
+
|
21 |
+
The dataset consists of structured logs recorded at the Ground Earth Station (GES), capturing communications between the Inmarsat satellite system and MH370’s terminal. Some non-essential columns have been removed for readability.
|
22 |
+
|
23 |
+
### Data Format
|
24 |
+
|
25 |
+
- All times are in UTC.
|
26 |
+
- The logs cover communications from 16:00 UTC on March 7, 2014, until the last Handshake Request (Log On Interrogation) at 01:16 UTC on March 8, 2014.
|
27 |
+
- Each log entry includes multiple fields detailing signal timing, frequency offsets, and transmission characteristics.
|
28 |
+
|
29 |
+
|
30 |
+
### Key Fields:
|
31 |
+
|
32 |
+
- **Time**: Timestamp of the log entry
|
33 |
+
- **AES ID**: Terminal identifier
|
34 |
+
- **Channel Name / Type**: Communication channel information
|
35 |
+
- **Ocean Region**: Satellite coverage area
|
36 |
+
- **Burst Timing Offset (BTO)**: Used to estimate the distance between the aircraft and the satellite
|
37 |
+
- **Burst Frequency Offset (BFO)**: Affected by Doppler shifts, useful for tracking movement
|
38 |
+
- **Signal Strength & Quality Metrics**: Includes power levels, frequency offsets, and estimated bit error rate
|
39 |
+
|
40 |
+
## Understanding Key Metrics
|
41 |
+
|
42 |
+
### Burst Timing Offset (BTO)
|
43 |
+
|
44 |
+
BTO values help estimate the aircraft's distance from the satellite based on:
|
45 |
+
|
46 |
+
- Signal travel time (ground station → satellite → aircraft → satellite → ground station)
|
47 |
+
- Fixed processing delays in the satellite, ground station, and aircraft terminal
|
48 |
+
|
49 |
+
BTO does not provide an exact aircraft location, but it helps determine possible flight paths.
|
50 |
+
|
51 |
+
### Burst Frequency Offset (BFO)
|
52 |
+
|
53 |
+
BFO values indicate Doppler shift effects on the signal, which depend on:
|
54 |
+
|
55 |
+
- Aircraft motion relative to the satellite
|
56 |
+
- Satellite motion relative to Earth
|
57 |
+
- Fixed biases from aircraft and satellite transmitters
|
58 |
+
|
59 |
+
Corrections applied by the Automatic Frequency Control (AFC) system in the ground station compensate for some of these effects.
|
60 |
+
|
61 |
+
## Applications of This Data
|
62 |
+
|
63 |
+
This dataset is valuable for:
|
64 |
+
|
65 |
+
- Aviation forensic analysis
|
66 |
+
- Reconstructing MH370’s possible flight paths
|
67 |
+
- Machine learning models for anomaly detection in aviation telemetry
|
68 |
+
- Understanding satellite-based tracking systems
|
69 |
+
|
70 |
+
## Citation & Acknowledgments
|
71 |
+
|
72 |
+
This dataset is based on publicly available Inmarsat logs used in the MH370 investigation. Credit goes to aviation safety researchers, satellite engineers, and data analysts contributing to this effort.
