GraVIS, is an created by Space App challengers from Trivandrum, India. This mobile app can map the gravity potential to your smart phone, where ever you are with a 200 meter accuracy. It finds your location with phone GPS and tells you the earths gravity at that point and you can also find gravity at any point on the globe by entering the geographic coordinates.

This project is solving the Gravity Map challenge.


This project aims to analyze the raw data from satellites like GRACE and using Earth Gravity model , WGS84 version. We used the equation for Geo potential at a point with contributions from spherical harmonic coefficients and solving the Legendre polynomials. We are used Eclipse for andriod to develop the app and Wolframalpha'd API for calculatiion of the potential
