Overview

CANSAT PAYLOAD MK3B is an open-source printed circuit board by its-villada, from the its-villada/mCALCAN repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 124.7 × 140.5 mm with 61 parts on 99 nets, routed with 569 tracks and 54 vias.

It is built around the SI2301DS, RFM95W-868S2 and BC817. Its parts include 13 resistors, 12 ICs, 11 connectors, 4 capacitors and 2 transistors. It belongs with the NXP (LPC, Kinetis, i.MX RT) boards of this library.

mCALCAN

Satélite CANSAT del instituto técnico salesiano Villada. Este desarrollo responde a la iniciativa conjunta entre la Comisión Nacional de Actividades Espaciales (CONAE) y el Ministerio de Ciencia, Tecnología e Innovación (MinCyT) tiene como objetivo principal acercar la ciencia y la tecnología a jóvenes en edad escolar, mediante la participación en la Convocatoria CANSAT Argentina.

Objetivos

Misión Primaria

Consiste en el sensado de presión y temperatura y la transmisión de esos datos a la estación terrena,al menos una vez por segundo. Mediante estos dos parámetros calcularemos la altitud, ya que tanto presión como temperatura varían con la altitud. Para el cálculo de la altura, nuestro CANSAT transmitirá los datos de temperatura y presión antes del despegue y de esa manera obtener los datos iniciales necesarios para el cálculo.

Misión Secundaria

Aprovechando y como complemento de la misión primaria, la misión secundaria consiste en medir la atmósfera y sus condiciones, con el objetivo de armar un perfil de atmósfera que pueda ser implementado, más adelante, como parte del modelo meteorológico internacional para la generación de pronósticos o la calibración de radares meteorológicos. Esto significa, que se medirán parámetros ambientales de presión y temperatura (tomados en la misión primaria), a los que agregaremos humedad relativa y porcentaje de CO2. Estos parámetros son medidos y correlacionados con las coordenadas (latitud, longitud y altitud) obtenidas por un módulo GPS.
