The launch of ÑUSAT-1, the second AMSAT ARGENTINA amateur satellite on May 30, will mark an extraordinary event for our Institution and fostering of hope for satellite community.
As we quoted when the announcement of the launching of this experiment, Amsat Argentina has been working for several years to keep alive the dream of many Argentine amateurs to get back into Space with their own satellite as a follow-on of the legendary 1990’s LUSAT-1, reaping the benefits of Technological advancement of our days.
We believe technical activities and developments of experiments in near space share the same goals: preserving the human group, enhancing their capabilities as well as disseminate and guiding the education and development of the activity, meanwhile contributing to Space available resources.
Our agreement with Satellogic Enterprises, which already launched three low orbit satellites: Captain Beto, Manolito y Tita, two of which transmit telemetry and data currently in UHF identifying themselves with callsign LU7AA, allowed us to ride a linear analog amateur radio transponder and corresponding antenna aboard one of their next satellite, ÑUSAT-1
AMSAT-LU provides simultaneously, support for this mission and the ÑUSAT-2 mission, by operating one of the control stations at Tortuguitas, Prov. Of Bs.As.
The experiment Amsat-LU developed, evolved from original design of our colleague and partner William, PE1RAH, while electronic adaptation, mechanical and software was made by the LU Satellite Experiment group, mounted on a 10 x 10 centimeters radiating plate, in which components of the power supply as well as a duplexer and dual band antenna where also incorporated.
This set was installed on the Ñusat-1 bus, which supplies power and becomes part of several other experiments this satellite will make.
The transponder receives UHF which is broadcasted in VHF, has a bandwidth of 30 kHz. with an output power of 250 mW.
435.935 ~ 435.965 are LSB/CW uplink passband
145.965 ~ 145.935 are USB/CW downlink passband
145.900 Basic CW Telemetry
The launch will be from a Chinese launcher in a polar orbit at 500 km. height, with inclination of 97 degrees from Equator.
