High-precision comparisons of the proton's and antiproton's charge-to-mass ratios and magnetic moments constitute stringent tests of CPT invariance, one of the cornerstones in the Standard Model of particle physics. The BASE collaboration has advanced these tests by precision measurements on single trapped antiprotons in a multi-Penning trap system in the antiproton decelerator hall at CERN, where magnetic field noise from the facility operation have become a major concern. To further advance the precision, we have designed the transportable antiproton trap BASE-STEP to relocate antiproton precision measurements into other laboratories. I will present a design report and the status of the project.
