GELE Geodesy — Satellite Geodesy and GNSSSlides
The slide format strips Satellite Geodesy and GNSS to the visuals that GELE reviewers remember best. Professional Regulation Commission (PRC) — Board of Geodetic Engineering's 2026 Geodesy papers reward reviewers who recognise the structure of a concept before they parse the item text; these slides train that recognition.
Exam context
Professional Regulation Commission (PRC) — Board of Geodetic Engineering runs the Geodetic Engineer Licensure Examination on September 2026. Its Geodesy section sits under a "Core" weighting, and Satellite Geodesy and GNSS is the 6th chapter in the 6-chapter GELE Geodesy rotation. The GELE passing mark is 70% weighted average, no sub-test below 50%, and the most recent 2026 paper drew about a meaningful share of questions from Geodesy.
