This document contains all the information and concepts necessary to define an observation strategy for STC, the stereocamera channel of SIMBIOSYS, and plan its observations. It first describes the constraints derived from the orbit of Mercury, the planning of BepiColombo mission, and the design of STC detector; then the possibilities offered by the software commanding the instrument are presented. Building on these constraints and possibilities, an observation strategy based on a “segmented orbit” concept is presented and illustrated with some practical examples
