ŅuSat 1, ..., 6 (Aleph-1 1, ..., 6)

ŅuSat 1 [Satellogic]

The Argentinian ŅuSat 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, ŅuSat-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 will be 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°. Four more will follow later in 2016.
