Objectives

• Understanding the shape of the Earth and different datums used to determine positionUnderstanding GNSS positioning and the factors affecting this positionsUnderstanding Inertial Navigation SystemsTake over levelling sessions and find difference of elevation

Outcomes

Describe the shape of the Earth in termsof potential and ellipsoidal modelsDescribe modern geodetic referencesystems and associated reference framesDescribe horizontal and vertical datumtransformation conceptsDescribe geometry of lines on theellipsoid and perform forward and inversecomputations on the ellipsoidal surfaceusing available softwareUndertake control surveys, establish,mark and describe control stations,describe horizontal positioningprocedures, apply appropriate methodsand use corresponding instruments forpositioningDescribe the deployment, calibration,signal structure and performance ofacoustic positioning devices.Describe the use of acoustic positioningsystems in offshore survey operationDescribe principles and use of IMU’sincluding north finding and heaveestimation.Compare IMU heading measurementswith magnetic and gyro compassesDescribe principles and use of IMU’sincluding north finding and heaveestimation.Compar
