The most precise CPT invariance tests in the baryon sector are currently conducted at CERN's world-unique antimatter factory. Within this program, the BASE collaboration compares the fundamental properties of antiprotons and protons using state-of-the-art cryogenic Penning-trap systems. To push the limits of our measurements to higher fractional accuracy, we built the autonomous, open, transportable Penning-trap system BASE-STEP to transport antiprotons to our dedicated high-precision offline laboratory currently under construction at Heinrich Heine University Düsseldorf, Germany. I will present the most critical milestone in realizing antiproton transport: The successful demonstration of all essential techniques required for its implementation using protons. Specifically, we achieved lossless transport of 100 trapped protons via truck across the CERN Campus and continued seamless operation of the system after transport. Our demonstration validates the feasibility of the concept, paving the way for future offline antiproton precision studies.
