Foundation position measurement using altimeters

A method of monitoring a foundation of a building, the method comprising:

• placing a plurality of altimeters at a corresponding plurality of locations in the building;
• measuring a measurement history of the plurality of altimeters by repeatedly performing altitude measurements by the plurality of altimeters over a time period;
• calculating, for each of the plurality of altimeters, a height history of a plurality of height differences among the plurality of altimeters by repeatedly calculating, over the time period, the plurality of height differences among the plurality of altimeters;
• and
• modeling, using the height history of the plurality of height differences, a modeled movement of the foundation over the time period.

A system for monitoring a position of a foundation of a building, the system comprising:

• a plurality of altimeters disposed at a corresponding plurality of locations in the building, wherein the plurality of altimeters further comprises a corresponding plurality of wireless transmitters;
• a wireless receiver configured to receive a plurality of signals from the corresponding plurality of wireless transmitters, wherein the plurality of signals represent a plurality of corresponding height measurements for the plurality of altimeters;
• and
• a processor configured to model, using the plurality of corresponding height measurements for the plurality of altimeters, a position of the foundation.
