Cubesat Simulator

AMSAT-NA lanserar nu en Cubesat-simulator som man kan låna (i USA antar jag) för att demonstrera hur en satellit skickar telemetri.

Cubesat Simulators Launched

Dr. Alan Johnston, KU2Y, Vice President – Educational Affairs has
announced the general availability of the AMSAT Cubesat Simulators.
Speaking at the 37th Annual Space Symposium, Alan reports that since
the prototype Cubesat Simulators were introduced at Hamvention in May,
2019, the simulators have undergone testing and final release. Among
the schools testing the simulators was Bishop O’Connell High School in
Arlington, Virginia. Science and Engineering teacher Melissa Pore
presented to the symposium audience her experience with using a
simulator in one of her engineering clubs and how her student
benefitted from their use.

A Cubesat Simulator is a self-contained satellite model that reports
solar cell performance via standard AFSK 1200 BPS AX.25 telemetry.
The telemetry can be decoded with a simple SDR ground station. A
Cubesat Simulator package consists of the 1U simulator, a halogen work
light to simulate sunshine, and a motorized rotating turntable that
mimics the satellite tumbling through space. The four loaner
packages are packed and shipped in a hard case. The simulator is
shipped prepaid while the user pays return shipping.

Persons interested in borrowing a CubeSat Simulator for a local
presentation is encouraged to contact Alan at KU2Y at amsat dot org.

The URE has again requested the Secretary of State for Digital
Advance the extension of the aforementioned administrative
authorization for a period of one year.

On September 26, the Resolution of the Secretary of State for Digital
Advance is approved by the resolution Authorize until

band 2,400,050 to 2,409,500 MHz., With a maximum eirp of 1500 watts
and using directive antennas with a gain not less than 22.5 dBi, from
authorized amateur radio stations located anywhere in the national
territory to the QO-100 satellite located in the 25.9ºE orbital
position of the geostationary orbit.
