T-RTK Sundial – Precision Sun Dial Designer

RTK Sundial creates a precision-aligned, real-world sundial design that’s automatically adjusted for your exact latitude, longitude, and date.

Unlike fixed traditional sundials, this system is dynamic:

• You can move the numbered stones or markings throughout the year to follow the seasonal solar shift.
• It works at any scale — from a small patio layout to a field-sized sundial mowed into grass.
• The KML export lets you visualize or survey your sundial using RTK GPS, drones, or mapping apps like SW Maps and Google Earth.

The project combines RTK precision, astronomical calculation, and practical field design — ideal for landscape artists, educators, farmers, or makers who want to merge science and design.

Key Advantages:

• Tailored to your exact location and date
• True-north reference for high accuracy
• Daylight Saving and Equation-of-Time correction
• Adjustable north offset for aerial or site alignment
• “Check Time” feature for verifying shadows on a specific date/time
• Works offline in a simple browser

Example Uses:

• Permanent garden or stone sundial that you can re-align seasonally
• Educational demonstration for sun movement and timekeeping
• Mowed or drone-mapped sundials for fields or large-scale installations
• Visual calibration for RTK mapping and solar tracking systems
