## Abstract

An example geolocation system for mounting on a mammal incorporates simple sensing sleeves on the calves of the body support members, combined with an accelerometer based gravity direction and force sensing at the center of mass of the body. The example system is connected to a digital processing unit and a battery power supply to integrate the sensing to determine kinetic and potential energy of the body locomotion over time in a method that integrates out the aperiodic motion of the body about the center of mass, and uses the residual motion to measure the center of mass locomotion from a known point.

## Claims

### Claim 1

A geolocation system for mounting on a mammal, comprising:
muscular force sensors for measuring muscular force exerted by support members of the mammal;
movement sensors for sensing movement in the Earth's magnetic field;
gravity sensors for sensing gravity forces at the center of mass of the body of the mammal; and
a processing system for using outputs of the muscular force sensors, the movement sensors and the gravity sensors to determine movement of the mammal.

### Claim 2 (depends on 1)

The system according to claim 1, wherein the muscular force sensors comprise calf muscle sensors provided as sleeves including interwoven, elastic-resistive strips.

### Claim 3 (depends on 2)

The system according to claim 2, wherein the movement sensors comprise magneto-resistive strips in the sleeves.

### Claim 4 (depends on 1)

The system according to claim 1, wherein the force sensors comprise accelerometers disposed at the mass center of the mammal.
