Calculable gravitational reference fields from engineered positive mass

Precision gravity and inertial sensors are difficult to calibrate against a known, controllable gravitational input. Elefanti Industries is developing the mathematics and engineering to produce such inputs from ordinary, well-characterized mass.

01The problem

A calibration source is useful only if its field is known. The goal is a gravitational reference whose signal is computed from measured masses and positions, can be switched between defined states, and is shaped to the sensor's working region.

02Technical foundation

  1. 01

    Mathematical field synthesis

    Constructing arrangements of ordinary positive mass whose Newtonian field is locally uniform, or matches a prescribed acceleration and gradient, in a defined working region — with rigorous limits on what a given configuration can achieve.

  2. 02

    Inverse source design

    Computational determination of manufacturable positive-mass distributions for a specified field objective, subject to density, geometry and fabrication constraints.

  3. 03

    Finite-volume source realization

    Translating idealized thin-source mathematics into realizable fixed-density three-dimensional bodies whose fields remain calculable.

  4. 04

    Precision source-mass engineering & metrology

    Source bodies, carriers, positioning, dimensional and mass metrology, trimming and uncertainty analysis so that a reference signal can be computed from measured quantities.

03Reference outputs

  • Uniform reference fields
  • Gravity gradients
  • Selected spatial derivatives
  • Positive / negative calibration states
  • Trajectory-weighted sensor responses
  • Differential and reversible calibration states
