What are E files and how to open them

Are you having problems opening an E file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your E files.

What is an E file?

E files have multiple uses, and STK Ephemeris Format Data is one of them. Read more about the other uses further down the page.

STK Ephemeris Format Data

Ephemeris files, used by the System Tool Kit (STK) software to analyze and visualize spacetime events, provide a predicted path of movement for an astronomical object (such as a planet, moon, or satellite) over a specific period.

STK utilizes precise ephemeris data to predict the speed and location of objects in space, taking into account the gravitational impacts of other celestial bodies and other elements that can impact their movement. This information can be applied for a variety of purposes, like mission planning and assessment, satellite monitoring, and navigating from one place to another in the sky.

The STK Ephemeris Format is an STK-specific file structure used to store ephemeris data. It features a text format composed of multiple records, each representing the position and velocity of one object at any specific point in time. Additionally, the header section in this format contains information regarding the details and duration of the data as well as positional and velocity values across all objects in said timeline.
