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 40 cm × 43 cm × 75 cm spacecraft of 37 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 satellite 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 consist of up to 25 satellites.
- The first two satellites, ÑuSat 1 and 2 were launched as piggy-back payloads on a Chinese CZ-4B rocket in April 2016 from the Taiyuan Satellite Launch Center into a 500 km sun synchronous orbit with an inclination of 97.5°.
- The third, ÑuSat 3, followed in 2017 also as piggy-back payloads on a Chinese CZ-4B rocket.
- Another pair, ÑuSat 4 and 5 will launch in early 2018 as piggy-back payloads on a Chinese CZ-2D (2) rocket.
- Three more, ÑuSat 6, 7 and 8 will follow in 2018 also as piggy-back payloads on a Chinese CZ-2D (2) rocket.
