GI3029 Advanced Geodesy Syllabus – Anna University Regulation 2021

COURSE OBJECTIVES:

 The objective of this course is to expose the students to the advancement in geodesy and to understand the international perspective of advanced geodesy and be able to cooperate internationally.

UNIT I GEODETIC CONTROL

Horizontal control – characteristics – method and standards for triangulation, traversing, trilateration, inertial and space techniques (Doppler GPS, SLR and VLBI) – computation – problems on spherical coordinates. Vertical control – characteristics – method and standards for spirit levelling, trigonometrical levelling and space techniques – computations- national networks.

UNIT II GEODETIC COMPUTATIONS

Rectangular and Polar Co – ordinates – First and Second geodetic problem – Similarity, Affine Projective and Polynomial transformation – methods of point determinations – problems on intersection, resection, arc section and also with over determinations, polar method and its extension.

UNIT III ASTRONOMICAL COMPUTATIONS

Variation in celestial co – ordinates, Determination of Astronomical Azimuth- stars altitude and hour angle methods, astronomical latitude and longitude determination – sources of errors and its eliminations- problems

UNIT IV HEIGHT SYSTEMS

Geo potential number – Orthometric height, Normal height, Dynamic height and their corrections – computation of orthometric height, Ellipsoidal height and its determination with a single and reciprocal observation of vertical angle – geoidal height – methods and computation.

UNIT V MISCELLANEOUS TOPICS

Crystal movements and plate motion – methods of determination of horizontal and vertical movements – dam deformation- earth tides – tidal forces, tidal response of the solid earth, tidal loading, analyzing and predicting earth tides, earth tide instrumentation – satellite altimetry – observations, computation and interpretation and application – Gravity Field Missions: satellite-tosatellite tracking – CHAMP and GRACE Satellite gravity gradiometry: GOCE.
