PstRotator for Windows

Product snapshot

PstRotator is a free Windows program built for ham radio operators who need precise control over antenna rotators. It handles both azimuth-only rigs and full azimuth/elevation systems, and is designed to simplify tasks like tracking satellites and moonbounce (EME) contacts.

Main capabilities

• Integrates with Software Defined Radios to streamline tracking and reception.
• Provides automated tracking for satellites and Earth–Moon–Earth (EME) paths.
• Controls Doppler adjustments to keep frequencies aligned during passes.
• Operates relays to manage auxiliary equipment and switching needs.
• Supports both azimuth-only and azimuth/elevation rotor configurations.
• Enables remote operation through serial connections or over networked hardware.

Remote access and interoperability

PstRotator can be controlled from a distance via serial ports or networked devices, allowing station owners to run rotators and related gear without physical presence at the rig. Its compatibility with other radio applications—especially SDRs—makes it easier to coordinate frequency control and pointing together.

Appearance and personalization

The application offers visual customization options such as skins and the ability to set custom map backgrounds. These features help users tailor the interface and display to match personal preferences or specific operational needs.

Who benefits from it

With an approachable interface and powerful feature set, PstRotator is suitable for newcomers learning rotor control and for experienced operators running complex antenna arrays and automated tracking routines.
