Chandler Wobble A small motion in the Earth's rotation axis relative to the surface, discovered by American astronomer Seth Carlo Chandler in 1891. Its amplitude is about 0.7 arcseconds (about 15 meters on the surface) with a period of 433 days. It combines with another wobble with a period of one year, so the total polar motion varies with a period of about 7 years. The Chandler wobble is an example of free nutation for a spinning non-spherical object.

“Siting a new flight center in central Washington will allow the state to build off of the established strengths of its thriving aerospace industry. The Flight Center supports the commercial growth of the UAS sector, attracting and additional aerospace research and development dollars, providing users with cost-effective, safe, flight testing facilities and fostering the development of more companies and high quality jobs in Washington.” Source: Bart Phillips, vice president for economic development for Innovate Washington, in comments made as a consortium of Washington state-based organizations ready submissions for the final section of a proposal to site an unmanned aircraft system research and testing facility
