ÑuSat 1, ..., 98 (NewSat 1, ..., 98, Aleph-1 1, ..., 98)

ÑuSat 1 [Satellogic]

The Argentinean 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.

Government of Albania contracted with Satellogic S.A. under the Constellation-as-a-Service model to provide Albania with responsive satellite imagery capabilities across its sovereign territory. Albania will have priority access to two satellites, which will be named Albania 1 and 2.

• 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 were launched in early 2018 as piggy-back payloads on a Chinese CZ-2D (2) rocket.
• Two more, ÑuSat 7 and 8 were launched in January 2020 also as piggy-back payloads on a Chinese CZ-2D (2) rocket.
• ÑuSat 6 followed in September 2020 on a multi-satellite launch on a Vega rocket.
• ÑuSat 9 - 18 additional satellites were launched in November 2020 on a dedicated CZ-6 rocket.
• ÑuSat 19 - 22 will be launched in July 2021 on the Transporter-2 rideshare mission on a Falcon-9 v1.2 (Block 5)
• The remaining satellites of the initial 90-satellite constellation will be launched on a mix of different launch vehicles, with Falcon-9 v1.2 (Block 5) being the primary launch vehicle.
