Ranging noise (m)

A GPS receiver knows its distance to several satellites from signal travel time. Each distance places it on a circle (a sphere in 3D); where three circles intersect is the fix. With perfect ranges they meet at one point, but timing noise blurs the intersection into a small region — which is why GPS uses many satellites and least-squares to pin down position.

Governing equation

(x - x_{i})^{2} + (y - y_{i})^{2} = r_{i}^{2}, σ_{r} = 0 m

Reading this result: With zero ranging noise the three distance circles meet at exactly one point, so the computed fix lands on the true position.

About this simulation

The full GPS Trilateration tool models a hiking trail with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
