RosCanSat or "satellite" in an aluminum can in Russian

    The III Russian CanSat Championship, which took place at the beginning of July in Taldomsky District, was successfully completed.

    CanSat is an operational microsatellite model weighing up to 350 grams. All the main elements of the "satellite" should fit in a 0.5 liter jar. The "satellite" is launched by a rocket or dropped from a helicopter from a height of 1-2 km and during a smooth descent by parachute transmits useful information.

    Thus begins all the official messages about the past event. A reader who is familiar with the CanSat format raises the question: “Stop! And why 0.5, not 0.33? ”, A reader unfamiliar with CanSat format raises the question:“ What is it? ”, As well as“ What is the use of a satellite model and such a small height? ”And others are the same associations.

    I was lucky to visit the jury of this competition and under the cut, I will tell you what the differences between CanSat'a Russian and his American ancestor are.

    Dauria strongly supports any space undertakings, including sponsoring Kansat competitions in Russia . Up to now nothing has been written on Habré about this movement, there are only a few mentions, and I decided to fill this gap.

    What is Kansat? You can consider this as a movement, you can look narrowly, then this is the very model of a microsatellite weighing up to 350 g. I see it as a movement designed to simulate the actual production of a spacecraft. Beginning in 1999, with the support of NASA, it was initially aimed at students of specialized universities so that they went through all stages of spacecraft production in a tangible time frame and saw an immediate result. The scientific and technical challenge in this case was not a battle with the adverse effects of cold space, but miniaturization. The device should fit into the dimensions of an aluminum can with a volume of 0.33 liters.

    But in Russia they went the other way, the weight remained the same, but the height was increased to a height of 0.5 l cans. As a result, "our" Kansat has not yet been integrated into the world community. But with an increase in the number of teams, I’m sure a test group will appear in the “classic” format. The second more important difference is the target audience. RosKanSat is aimed primarily at schoolchildren, at the last competition the youngest participants studied in the 6th grade!

    In world practice, competitions are divided into several classes. This is the “classic” Kansat, they throw a jar onto a rocket and it must transmit telemetry in an uncontrolled descent. There is a class with controlled descent, the device should return to the starting place. There are launches to a height much greater than 1-2 km - to the stratosphere. But so far only a “classic” version is being held in Russia, this is called the regular league. However, there were several teams that tried to implement a controlled launch.

    The obligatory Kansat program is telemetry of pressure and temperature sensor indicators. And additional functions depend on the wishes of the team. What interesting things can be done from such a "jar"? Apart from the invaluable experience in designing and manufacturing a complex system, as well as programming, working with radio broadcasts, the options for additional payload were very diverse.

    The team that won the Rara Avis regular league installed a set of sensors for weather monitoring on their CS: a humidity sensor, an additional temperature sensor.

    The team that took the second place - ISS-17, without deviating from the task, simply duplicated all the main sensors, and also took care of thermal insulation.

    The third important difference of RosKanSat from world analogues, in addition to the dimensions of the devices and the target audience, is the presence of the “Higher League”. Strictly speaking, this is no longer Kansat, it doesn't smell of jars of soda. In format, it is already much closer to CubSat. Weight PN - 1kg. And the payload itself, like the tasks, is much more interesting. The obligatory program of the Major League is telemetry, determining the position of the device in flight according to the readings of the magnetometer, and the delayed operation of the rescue system at an altitude of 200-400 m.

    The winners are the Belarusian team.

    And their device with an IR camera.

    The guys took pictures in the IR range, as well as highlighted the red range from the visible. And based on this data, we calculated NDVI for the launch site! It turned out, of course, no NDVI, as nobody was engaged in rationing. But the results are still impressive.

    There have been projects in the Premier League of non-standard reduction systems. Usually it's a parachute. But the Gagarin-M team had an absolutely fantastic project to reduce with the help of an impeller. Unfortunately, insufficient study of the project did not allow for flight tests.

    The runner-up team, Galaxy, said a soft landing, but unfortunately the fired thread did not work due to the oncoming air flow. And the device flopped without any parachutes, but it turned out to be safe and sound!

    Unfortunately, not all participants from the regular league had a soft landing. In the photo of the CC of the Rokot team. He is at the beginning of the article.

    Since this year, competitions have received informational support from Roscosmos (And in the future, the Roskosmos logo can be used in the RosKosSat logo), so I hope the movement will develop. I know that on Habré there are many people who are not indifferent to the education of schoolchildren who are organizing various radio engineering circles. For them, the participation of their wards in such competitions can be a good goal!

    Lastly, a few more pictures from the "fields".

    Field Mission Control Center. And the flight manager - Nikolai Nikolaevich Vedenkin - Project Management Director of the Moscow branch of Dauria.

    Start preparation.

    Unfortunately, not all starts were successful.

    And because failed to establish accident-free launches of heavy VL apparatuses, so they were thrown from the hexocopter.

    On this I would like to finish my story. I will be happy to answer questions in the comments. Sorry for some confusion, the Chukchi is not a writer. I hope that the topic will be interesting to the habrasociety, and perhaps eventually it will acquire its own hub. I would like this movement to develop.
