Super‑E, developed by u-blox, is short for Super‑Efficient: Super-E is an intelligent power mode that reduces overall power consumption without impacting positioning performance. It uses only the minimal resources required for tracking and maintaining an accurate position, as opposed to the full‑power operation, which always tries to maximize positioning performance. https://www.u-blox.com/en/super-e-technology
