Gravity Probe B (GP-B) is a space mission which used a satellite with 4 super-accurate gyroscopes to test the frame-dragging effect predicted by general relativity theory. The satellite was launched on April 20, 2004, and the spaceflight phase of the mission lasted until 2005. The GP-B science team alleges that highly predictable and systematic malfunctions in the gyroscopes created signal noise, and when the signal noise is removed from the empirical data, then Gravity Probe B confirms the precise frame-dragging effect predicted by general relativity theory without the Rañada-Milgrom effect. However, if the gyroscopes functioned within design specification, then the alleged defects in the gyroscopes might be confirmations of the Rañada-Milgrom effect.
