SURVEYING ASTRONOMY FOR LAND SURVEYORS - PART 1A WEBINAR (#1516)
Length: 02:00


David Rolbiecki, RPLS, LSLS and Bill O'Hara, RPLS, LSLS present four 2-hour webinars on surveying astronomy for land surveyors moderated by Paul Carey, RPLS, LSLS. These webinars will study the fundamentals of astrometric observations which has become a lost science and art ever since the advent of satellite positioning technology. 

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.
