One measurement is not a trajectory. Monthly tracking will re-measure this page with the same method and send you its dated report every month: the evidence a “trajectory” criterion in a tender asks for. This service is not open yet. Leave your email and we will tell you when it opens. No commitment.
Your address is used only to tell you when tracking opens. It is deleted on request at perennova@proton.me. See the legal notice (in French).
