DUMMY SAT 3

Launch Vehicle Mass Simulator (Not a Functional Satellite) · Launch Vehicle Provider

Dummy Sat 3, a mass simulator flown to validate a rocket's payload deployment sequence — not a functional satellite at all, simply a precisely weighted object standing in for a real payload during a technology or launch vehicle test. Mass simulators like this one are common on early or experimental launch vehicle flights, where engineers want to validate the rocket's deployment mechanics without risking an expensive real satellite on an unproven system.
