The Technology That Makes This Possible
The Technology That Makes This Possible
Cold Atom Interferometry
Rb atoms are cooled down inside a vacuum chamber using lasers
At close to 0 K, the wave nature of atoms becomes apparent
Interference of these matter waves is contingent on gravity

Limitations of techniques utilized in the construction industry that overcomes

Conventional Gravimeters - Relative gravimeters like the CG-5/CG-6 work by comparing the extension of a spring, to which a mass is attached, to a base station. Since springs do not retain their length over a long period of time, there is drift in the measurements and the device needs to be frequently calibrated.

>
Mechanical drift - Cannot take consistent measurements a long period of time

>
Static measurements - Slow data acquisition alongside manpower costs

Ground Penetrating Radar (GPR) - Works by emitting radio waves into the ground and detecting the reflections. These signals attenuate in the ground by being absorbed or reflected away and thus, the signal cannot penetrate greater depths than 2 m in the real world. Using a lower frequency signal improves depth capabilities but at the cost of resolution.

>
Affected by moisture other aspects of soil composition, which affect signal quality, penetration depth, and locational accuracy

>
Depth limitation of 2 m in Singapore - Not useful for deeper targets

Trial Trenching - Involves excavation work to establish the location, size, and orientation of underground utilities.

>
Long turnaround times due the slow speed of excavation, further exacerbated by the need for relevant permits

>
Limited information between trenches due to discrete observations
