The Lemur-2 TRUTNA Satellite, part of Spire Global’s CubeSat Constellation, re-entered the atmosphere on April 15, 2018 after over one year in orbit collecting global ship-tracking data and measuring atmospheric parameters.
Spire’s 3U CubeSats carry a pair of payloads – STRATOS, a GPS receiver for occultation measurements that yield atmospheric data relevant for operational meteorology, and SENSE, a receiver for the Automatic Identification System to collect tracking data for ship traffic across the globe.
