Surveying & Geodesy

Surveyor holding a GPS rover pole on a tripod in an open field — A surveyor with a total station harnesses GNSS signals to deliver millimetre-precision measurements that shape accurate, reliable infrastructure.

GNSS Satellite Signals Drive Millimetre-Precision Surveying

1
GNSS Constellation
GPS, GLONASS, Galileo broadcast ranging codes
2
Reference Station
Fixed CORS station measures real-time corrections
3
RTK Processing
Carrier-phase differencing resolves centimetre positions
4
Survey Rover
Field crew captures boundary and elevation data

Satellite ranging signals, corrected at fixed reference stations, enable field rovers to achieve centimetre-level geodetic accuracy.

Applications

2.8.1 Land Survey Systems — Providing centimetre-accurate ground positioning for cadastral, agricultural and civil-engineering surveys using a sovereign GNSS correction and augmentation constellation.
2.8.2 Infrastructure Surveying — Using satellite-derived radar and optical data to precisely monitor the structural geometry, settlement and deformation of critical national infrastructure at scale.
2.8.3 Geodetic Mapping — Establishing and maintaining a sovereign geodetic reference frame by fusing satellite radar interferometry, GNSS tracking and gravimetry into a continuously updated national datum.
2.8.4 Earth Measurement Systems — Continuously measuring Earth's shape, gravity field and rotational parameters from orbit to anchor every national coordinate system and geophysical monitoring programme.
2.8.5 High-Precision Terrain Models — Generating sub-metre digital elevation models of national territory using spaceborne radar interferometry and stereo optical imagery for defence, infrastructure and disaster planning.
