Celestial Sun Navigation Spreadsheets

Enjoy exploring this page featuring celestial sun navigation spreadsheets, which are part of one of the eight identical exercises you should resolve. However, tackle the exercise on this page only after completing the foundational La Rochelle exercise.

The main goal of these exercises is to calculate and understand how to calculate the line of position with the sun in daytime.

Furthermore, on this page, we want to underscore the importance of the spreadsheet, also called proformas or worksheets, which will guide you throughout from the observation until the end of the fully calculated line of position, formulas included

The sea around Pointe-à-Pitre (Guadeloupe)

Indeed, the sea around Guadeloupe, a French Caribbean archipelago, is part of the Caribbean Sea.

The region boasts turquoise waters, coral reefs, and a rich marine biodiversity. In fact, Guadeloupe is surrounded by the Atlantic Ocean on the eastern side and the Caribbean Sea on the western side.

Furthermore, the Caribbean Sea, known for its warm temperatures and vibrant coral ecosystems, contributes to Guadeloupe’s appeal as a popular tourist destination.

The marine life includes colorful coral formations, tropical fish, and endangered sea turtles.

Guadeloupe’s waters offer opportunities for snorkeling, scuba diving, and water sports. However, the area faces environmental challenges, including coral bleaching and the impact of climate change on sea life.

Moreover, conservation efforts aim to protect and sustain the delicate balance of the marine ecosystem around Guadeloupe.
