In Part 1B, the student will learn how to interpolate Nautical Almanac data in order to solve the Astronomical Triangle using spherical trigonometry; use interactive and web-based aids to solve Celestial Navigation problems; apply over-the-horizon navigation by dead reckoning and computing a Celestial Line of Position; determine latitude of your position at Local Apparent Noon; and determine longitude of your position by Equal Altitudes.  At the end of Part 1B, students will participate in three Practical Exercises covering what they learned in Parts 1A & 1B. 

Students who participate in all four parts will leave with the confidence and skills to train surveyors and field crews on how to perform field astrometric observations by “following the footsteps” of their predecessors.

This course is ideal for young surveyors who were raised on satellite positioning technology. All surveyors with varying degrees of experience are encouraged to attend. Experience in trigonometric functions is required. The student should bring a calculator that can convert degrees-minutes-seconds to decimal degrees and back, engineer scale, protractor, parallel rules (may be substituted using drafting triangles), and a mechanical lead pencil.
