1Geodesy is the science of measurement , including what?
Terrestrial, external gravity field determination
2What are the classifications of satellites?
Artificial and Natural Satellites
3Refers to the actual force exerted due to gravity between two specific masses.
It has a magnitude and direction, so it’s a vector quantity.
Gravitational Force
4Refers to the phenomenon or field itself — the natural attraction that pulls objects with mass toward each other.
It is a property of nature described by Newton’s law of gravitation and Einstein’s theory of general relativity.
Gravity
5What are the Key elements of Geodesy?
Measurement: Quantifying Eart as a size/shape
geometry: modelling as an Ellipsoid
Gravity: accounting for gravitation variation
6What scale does it operate?
Planetary Scale
7What Instrument measures Gravity?
Gravimeter

Dividing the earth
9What does "desa" mean?
divide
10What is the earth model used in Geodesy ?
Curved (Ellipsoid, Geoid)
11What is the Earth model used in Surveying?
flat (plane/Geometry)
12What are the tools used in Geodesy?
GNSS, gravimeter
13What instruments are used in surveying?
Optical tape
14What is the accuracy requirement in Geodesy?
cm to mm level
15What is the accuracy requirement in surveying?

Astronomical Geodesy
20It encompasses the three-dimension (3D) geometrical
elements of the ellipsoidal model of the Earth and the location of
points relative to a specific model
Geometrical Geodesy
