NuSat 3



The Argentinian ÑuSat earth observation satellites form the Aleph-1 constellation developed and operated by Satellogic S.A.

The satellites in the constellation are identical 51 cm × 57 cm × 82 cm spacecraft of 37.5 kg mass. The satellites are equipped with an imaging system operating in visible light and infrared. The constellation will allow for commercially available real-time Earth imaging and video with a ground resolution of 1 m. The satellites were developed based on the experience gained on the BugSat 1 (Tita) prototype satellite.

An U/V transponder with 2 W of output power for 8 GHz downlink and 2 GHz uplink will be operating on 100 kHz bandwidth. For backup telemetry, designers are considering UHF transponder operating at 9k6 GFSK. Additionally, ÑuSat-1 carries a U/V linear transponder called LUSEX provided by AMSAT Argentina (AMSAT-LU) to offer services to the HAM community.

The Aleph-1 constellation will initially consist of up to 90 satellites for weekly world remaps with the intention of ultimately having daily world remaps with approximately 300 satellites.
