The Power Distribution Module 2.0


This sub-component is responsible for stabilizing and supplying voltage for the extremely sensitive electronics to the rest of the science instrument. By providing stable voltages (in some cases between +/- 1 mV !), we maintain high precision in our scientific measurements.

As anything we do, practice makes perfect. This board is our 2nd full revision, after iterations from initial testing (rev 0) to HASP 2017 (rev 1.0)'s fully assembled and functional model.

NEUDOSE payload overlooking Earth on HASP 2017

With days until our HASP 2018 mission (High Altitude Student Platform), we look back on our accomplishments and in what went right in last year's mission success. Last year, we sent up our first payload to about 34 km altitude. After heavy focus on maintaining the structural integrity of our payload, the mechanical structure successfully survived the landing process. Seeking continuous improvement from last year, we have since refined the electrical systems.

What's happening this summer? (HASP 2018)

This summer, we will be participating in the HASP (High Altitude Student Platform) 2018. This annual flight program consists of a student-designed platform carrying 12 compact satellites, prototypes, and small experiments to 36km altitude with a balloon. After successfully participating in this event last year, we look forward to putting our hard work to test in preparation for our future mission launch from the ISS. 

Boards are coming in!

Preparation for HASP 2018 has been underway the last few months, and with it we have been getting our Printed Circuit Boards (PCBs) manufactured. Here is a preview of our work on the ADS team's board. We will be populating the board with all the required parts in the following weeks. The board will use a combination of an accelerometer, gyroscope, and magnetometer to determine the attitude of the satellite (the orientation, rotation, and velocity).  

NEUDOSE at Bruce Power

Luis, Diana, Eric, and Dr. Andrei Hanu attended Bruce Power's license renewal hearing by the Canadian Nuclear Safety Commission. Displaying our hard work and current mission progress, showing how Bruce Power gets involved in the community through their sponsorship of McMaster NEUDOSE. This public involvement helps to link us with the science community to ask us questions and provides a teachable opportunity.


Hira and Liubov place 1st in L3 WESCAM hackathon


Earlier this month, Hira Nadeem and Liubov Trofimova from the Command & Data Handling team participated and placed 1st in L3 WESCAM's first hackathon, HackWESCAM. In 36 hours, their team WeCycle used a trained neural network in a mobile app to scan and classify items to determine which recycling bin to place them in. An app like this would use geotagging to verify municipal recycling rules are being followed. Congratulations Hira and Liubov!

We're going to space!

Today, the Canadian Space Agency has announced that as part of their Canadian CubeSat Program (CCP), the McMaster Interdisciplinary Satellite Team's NEUDOSE satellite will be launched from the International Space Station in 2021! A testament to the hard work and dedication of our team leaders and members, the NEUDOSE satellite will be launched and deployed from the ISS by the Canadarm after being (likely) delivered by a SpaceX Falcon 9 rocket.

We are extremely honoured and thankful to the CSA and our sponsors for providing this incredible opportunity. We will do our best to make to make Canada and our national space agency proud!

Out of this world

Check out this latest rendering of the satellite structure, as designed by our mechanical team. The mechanical team's primary goal is to develop the structures that house all of the critical components of the satellite and radiation detector system. They also ensure the satellite is designed to the CubeSat dimensional and structural requirements for space flight. The mechanical structure will be tested as required by the team and launch provider.

The Design Process (with Altium Designer)

We are very thankful to our major sponsor Altium for providing us with Altium Designer software for designing Printed Circuit Boards (PCBs). Once our team designed the board, we had the board printed by the manufacturer based on the layout in the video. Once received, we assembled the board by applying solder paste, and heated it in a reflow oven.

This board in particular, designed by CDH team members Akiv and John, will be used in our HASP 2018 mission as the flight computer that handles data and monitors power in other systems. It was our first revision and many modifications were made from the errors discovered in the process.
