GPS & Relativity (orders of magnitude)
This interactive simulator explores GPS & Relativity in Astronomy & The Sky. Weak-field + SR clock drift estimates vs altitude and orbital speed. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Best once you already know the basic definitions and want to build intuition. Typical context: Astronomy & The Sky.
Key terms
- gps

Near GPS-like MEO values (~20 200 km, ~3.9 km/s), the gravitational gain and special-relativistic loss partially cancel; the net effect is on the order of tens of microseconds per day — the same order as the rough sum of the two terms shown in the sidebar.
How it works
Navigation needs nanosecond timing; ignoring relativity would accumulate large range errors — engineers apply both corrections routinely.
