Developing a SatBox using an ESP32-S3 MCU (July 9, 2026)
'Would it be possible to create a controller that can track satellites without a computer?'
That's how the development of SatBox began.
SatBox.This includes satellite orbit calculation, AOS/LOS prediction, and integration with Doppler correction.
Our goal is to achieve automatic control of the antenna rotator with a single unit.

In the future, I hope to be able to incorporate Doppler control for wireless devices.
Examples of automatic antenna tracking systems for amateur satellites include the ST2 from FOXDELTA.
However, these require PC software such as SatPC32 and will not work on their own.
 

What is SatBox?
SatBox is a standalone amateur satellite tracking controller equipped with an ESP32-S3.
The goal is to achieve the following functions with a single device, without requiring a computer.
 Regular downloads from NASA.ALL (TLE).
 Registration and management of tracking satellites.
 Countdown display until AOS/LOS.
 Display of AOS azimuth (Az) and maximum elevation (Max El).
 Real-time display of Az/El satellite tracking.
Real-time monitoring via web browsers on PCs and smartphones.
 Automatic control of antenna rotators
You can send an email alert before the satellite's AOS (Adaptive Operation System) is launched.
Doppler shift correction for wireless transceivers (planned for development)

 Boot screen
Manual control screen for the rotator.
Rotation is not possible between 0 degrees and 360 degrees (450 degrees) for Az, and between 0 degrees and 180 degrees or more for El.
The currently selected satellite list.
You can choose whether to perform rotational control using the checkbox.

 
Real-time monitoring via web browser from a PC or smartphone.

A list of satellites is displayed, along with a countdown to when AOS will be activated.
Additionally, you can continuously track satellites that have been checked in the checkbox.
You can list up to 10 stations.

 
Setup Menu.
Various setup menus
Network Setup
This is the setting for accessing the site from a PC or smartphone using a web browser.
Station Setup.
Enter your station's call sign, latitude and longitude, altitude, time zone, and grid locator.
 Satrllite selection.

You can select the necessary satellite from the satellite names in the NASA.all file.
Rotator Calibration. 
Rotator Calibration
The automatic control section for the rotator is also complete.
You can send an email alert before the satellite's AOS (Adaptive Operation System) is launched.
