Gravisat presented world's first relativistic gravimeter at IAC

Gravisat team presented its new paper at IAC in Paris covering world's first autonomous relativistic gravimeter developed for the Cubesat spacecraft constellation to monitor Earth's gravitational field in real time. 

This will enable earthquake predictions 24-38 hours beforehand and will help to save millions of human lives significantly reducing the economical damage from the earthquakes.

Gravisat's gravimeter can simultaneously measure the absolute value of the free fall acceleration, its relative change and the gradient along three axes. Its working model is based on the utilization of the relativistic "redshift" effect, that’s why we named the device a relativistic gravimeter.

Newtonian VS Relativistic:

- Historically, all gravity measuring missions have been accomplished by using the Newtonian ballistic principles. Moreover, all existing gravimeters are the accelerometer variations that can’t measure the gravitational field in space autonomously.

- Only relativistic gravimeters can solve the issue of measuring the parameters of the gravitational field in a fully autonomous mode by utilizing a radiophysical method, based on the measurement of the relativistic gravitational frequency shift of electromagnetic emission.

Here is The Paper.
