The Low Earth Multi-Use Receiver (LEMUR)
The Low Earth Multi-Use Receiver (LEMUR) is Spire’s 3U CubeSat platform used to track maritime, aviation, and weather activity from space.
Today, each 10x10x34.5 cm LEMUR is designed, built, and operated in-house by Spire. Less than 6kg, the LEMUR is powered by a deployable solar array, flying at 400-650 km in orbit for about 2 years. As of July 2018, each LEMUR carries an AIS, GNSS-RO, and ADS-B receiver.
