Telemetry Data

A collection of telemetry captured from SpaceX Launch Webcasts

The telemtry in this repository has been moved to the Launch Dashboard API.

Structure

The Telemetry is available in three formats: JSON, Excel and JSON Streaming.

Each directory contain the following files:

• < Launch name > raw - a file contaning the time, velocity and altitude caputred from the webcast in 30 fps. Usage of this file is not recommended due to the mix of telemetry of the first and second stage (see stage1 raw and stage2 raw below).

• stage1 raw - a file contaning the time (s), velocity (m/s) and altitude (km) caputred from the webcast in 30 fps of the first stage. This file only exists if there is available telemetry.

• stage2 raw - a file contaning the time (s), velocity (m/s) and altitude (km) caputred from the webcast caputred in 30 fps of the second stage.This file only exists if there is available telemetry.

• analysed - a file contaning Telemetry calculated using the raw files (more details below).

• events - a file contaning the time of several specific events (rounded to the nearest second). For example: MECO, Max-Q, Entry Burn Ignition etc.

• stages - a file contaning the beginning of the webcast telemetry of each stage. This file does not exists in Excel format

Analysed files

The analysed files contain telemetry that can be calculated from the raw data in 1 second interval.

These files contain the following fields:

Time (s), Velocity (m/s), Altitude (km), Vertical Velocity (m/s), Horizontal Velocity (m/s), Acceleration (m/s^2) (with gravity), Downrange Distance (km), Velocity Angle (degrees), Aerodynamic Pressure (N).

The files contain data from T+0 until the telemetry is cut. Each launch has analysis of either stage 1 or 2. The analysed stage can be found in the Launches file in the field analysed_stage.

The Launches.json file

The Launches JSON file contains links to the telemetry files described above.

The flight_number is consistant with the r-spacex database.

The Events.xlsx file

A Spreadsheet that compares telemetry of Specific events between launches (Like MECO altitude or Stage 1 apogee).

Example

This is the JSON Object representing the Orbcomm OG2 launch.

Future Developments

• Setting up a database and domain to host the files.

• Integration with the r-spacex database

incorrect

the velocity and time data for this launch is incorrect if you refer back to the official video by SpaceX
