Spire LEMUR payload for space-based reception of Automatic Identification System vessel signals.
SENSE AIS receiver is a passive RF payload for space-based reception of AIS vessel messages. It collects shipborne AIS broadcasts from orbit and is used with terrestrial AIS collection in downstream maritime tracking services [1][2]. Its receiver frequency set is 161.975 MHz and 162.025 MHz, corresponding to AIS 1 and AIS 2 VHF channels [3]. The payload observes vessel identity, position, and voyage broadcasts rather than imagery, so its buyer relevance is maritime traffic awareness, fleet monitoring, and in-situ signal collection from areas where terrestrial receiver coverage is incomplete [4][2].
