TI-Nspire™ CX
A dependable platform for a complete navigation system

Vincenta was designed around the TI-Nspire™ CX graphing calculator — transforming a proven, energy-efficient computing platform into a complete electronic celestial navigation system.

Unlike a phone or tablet, the TI-Nspire™ CX is a dedicated device that remains available whenever you need it. No notifications, no competing applications, and no dependence on an Internet connection.

More Than a Calculator

The TI-Nspire™ CX was originally developed as an advanced educational computing platform. However, its powerful processor, colour display and flexible software environment make it equally suitable as a dedicated navigation computer.

With Vincenta installed, the calculator becomes a self-contained celestial navigation instrument capable of performing sight reduction, celestial body identification, running fixes, plotting and navigation analysis.

Why Not Use a Phone or Tablet?

Modern devices are powerful, but independence requires a different approach.

Always Available

A dedicated navigation device is not competing with communication, entertainment or everyday applications.

Long Battery Life

The TI-Nspire™ CX is designed for very long battery life operation, making it practical during extended offshore passages.

Simple and Reliable

No mobile signal, Internet connection or app store is required to perform celestial navigation.

Built for the Cockpit

No power cables stretching through the companionway. The TI-Nspire™ CX is lightweight, cordless, and fits in an oilskin pocket, allowing you to verify sights and identify stars directly on deck while observing.
