Optical atomic clocks demonstrate a better stability and lower systematic uncertainty than the highest performance microwave clocks. However, best performing optical have large footprint in laboratory environment require specialist skills to maintain continuous operation. Growing evolving needs across several sectors are increasing demand for compact robust portable devices at this capability level. In paper we discuss design of physics package laser-cooled 88Sr+ clock that would, with further development, be suitable space deployment. We review parameters target relative frequency low parts 10^18 system. then explain results finite element modelling simulate response ion trap vacuum chamber vibration, shock thermal conditions expected during launch Additionally, an electrostatic model has been developed investigate relationship between geometrical tolerances trapping efficiency. present from these analyses led more prototype ready experimental testing.
