## Description

W1ANT Satellite Tracker is a powerful Chrome extension designed for amateur radio enthusiasts. It allows users to find and track amateur radio satellites visible from their current location within the next 24 hours. The extension provides detailed overviews of satellite paths from acquisition of signal (AOS) to loss of signal (LOS), showing only passes above a customizable minimum elevation.

Users can access detailed information about each satellite's on-board radios, including the exact frequencies for uplink and downlink adjusted for Doppler effect. A unique feature lets you point your phone directly at the selected satellite radio for easy operation. The extension also includes an interactive Location view displaying the satellite's real-time position over Earth and its path for the next hour, along with a Passes view listing upcoming satellite passes over the horizon in the next 48 hours. This tool is invaluable for satellite tracking and amateur radio communication planning.

## Review summary

Users appreciate W1ANT Satellite Tracker for its accuracy, user-friendly design, and responsive developer who adds popular features like dark mode. The paid version is recommended to avoid disruptive ads. Common issues include intrusive advertisements in the free version, unclear units and time zone info, occasional bugs causing app crashes, and limited filtering options. Overall, it is a well-regarded app for satellite tracking tasks, especially with the ad-free paid upgrade.

### Pros

- Provides essential and accurate satellite tracking information useful for antenna pointing and satellite communication.
- User interface is neat, clean, and easy to use, with all necessary info accessible.
- Developer is responsive to feedback and updates app regularly, adding requested features (e.g., AO-27 satellite, dark mode).
- Paid version offers an ad-free experience and additional features, recommended by users.
- Supports advanced functions like doppler shift calculations and has potential for integration with rig control software.

### Cons

- Free version has very intrusive and annoying ads including full-screen video with lock-out timers.
- Lack of units labels (e.g., for satellite height) and unclear time zone in settings leads to confusion.
- Some bugs cause app not to load or open on certain devices after updates.
- Missing certain filtering options, e.g., filtering for FM satellites or desired satellites only.
- Some frequency data initially inaccurate but corrected after user feedback.
