.TLM File Extension

A .TLM file is a Telemetry Data File, created by N/A.

Open with All Platforms. Available for Windows.

What is a .TLM file?

A .TLM file is a type of data file specifically used to store telemetry information. This information comes from aircraft, such as airplanes, or spacecraft, like satellites. The data in a .TLM file is saved in a binary format, which means it is not immediately readable like text files and is specific to the manufacturer of the aircraft or spacecraft.

Telemetry data in a .TLM file can include a variety of information depending on what the aircraft or spacecraft is monitoring. This might be scientific data collected by instruments measuring different environmental factors, temperature readings from various parts of the craft, or images captured by onboard cameras.

To access and use the data stored in a .TLM file, you typically need specialized software provided by the manufacturer of the aircraft or spacecraft. This software is designed to open, display, and analyze the data, making it understandable and useful. For example, it can help engineers and scientists to review the performance of the craft or the environmental conditions it encountered.

If you do not have access to the manufacturer's software, you might also try using a hex editor, such as HxD or HHD Software Hex Editor Neo. These tools allow you to view and edit the raw binary data. However, interpreting the data correctly without specific knowledge of the file format can be challenging.

.TLM files are primarily used in the aviation and aerospace industries, where monitoring and recording detailed telemetry data are crucial. The structure of a .TLM file can include multiple sections, each logging different types of data with timestamps in Unix epoch time, which counts the seconds since January 1, 1970.

In summary, .TLM files are essential for storing complex telemetry data in the aviation and aerospace sectors, and accessing this data requires specific software or advanced tools like hex editors.
