'Pratham' is the first satellite under IIT Bombay Student Satellite Project, designed and built exclusively by the students of IIT Bombay at a cost of INR 10 million.
It was launched on-board PSLV-C35 on 26th September 2016.
The payload of Pratham was to measure the Total Electron Count (TEC) in the ionosphere over India, using Faraday Rotation.
After the launch, the beacon signal of Pratham was received at multiple locations around the world. Since the downlink signal
wasn't received, the mission was deemed 90% successful.</p>

<p>On the technical front, the TEC would help correct GPS signals, which get distorted when passing through ionosphere
and help make GPS more accurate. Also, in certain extremely rare and special scenarios, the TEC values could help predict Tsunamis. <br /><br />
In addition, this project took IIT Bombay into the space age. A project like Pratham enables
students to apply the concepts they learnt in theory to practice. Also, the scale and complexity of such
a project introduces students to real world problems, where resources including timelines are scant and team dynamics are complicated.
<br /><br />
Finally, the social goal of Pratham (involving other colleges and universities in satellite and space technology) enabled the propagation of enthusiasm and knowledge
related in various colleges of India. </p>

<p>I was involved with the Student Satellite Project for all 5 years of my stay at IIT Bombay. I joined in the Electrical Subsystem in
my first year at IIT Bombay and was leading the Subsystem when Pratham launched. Later I headed the work on Advitiy, the second satellite, as the Project Manager.
The following points would briefly summarize my work in Pratham.
<ul>
<li>Spearheaded the Power system; ensured detection of Pratham's separation from the PSLV and subsequent power-up,
apt storage and distribution of solar power, battery charge management and health monitoring of critical components</li>
<li>Devised and executed the functionality test plan for monitoring key parameters during environmental tests at ISRO</li>
<li>Enacted SPI, I2C, UART protocols between ATmega128 micro-controller of the On-board Computer and sensors, actuators, peripherals</li>
<li>Implemented the AX.25 error detection protocol to packet the telemetry data sent and received by Pratham</li>
<li>Reviewed 10,000+ pages of documentation; presented before ISRO Scientists in the Critical Design Review and
Pre-Shipment Review to obtain a launch slot for Pratham</li>

<p>The satellite, as explained in the "About The Project" section, achieved 90% success, since only the
beacon signal was received and not the downlink. A few minutes after the launch of the satellite,
the Prime Minister of India tweeted a congratulatory message for the team. Two days later, the Governor
of Maharashtra personally felicitated us at his residence. However, I believe that the greatest impact
of this project is that today, there are children in India, who can dream about having their
own satellite orbiting the earth before they even graduate, and this dream doesn't seem too ambitious.

<p>This project had a life-changing impact on me. Working in the satellite team made me confident that
I can work in a long and demanding project, even overwhelm myself, if the end-goal is challenging
and ambitious enough. It introduced me to the various uncertainties and surprises (both technical
and non-technical) that welcome one in the course of the journey and gave me the confidence that
I can be deal with them. It showed me that I enjoy learning new things, outside my comfort zone,
especially if the learning complements my existing knowledge and takes me closer towards a specific
goal. I majored in Mechanical Engineering in IIT Bombay. However, in the Satellite Team, I was
recruited in the Electrical Subsystem. I went on to lead the Electrical Subsystem, interface with
the On-Board Computer and Communications Subsystem and eventually went on to take Systems
Engineering and Project Management roles. I joined the team with no knowledge of programming and
ended up co-authoring the flight code of Pratham (> 10,000 lines). This project also helped me develop a system-level perspective in decision-making. Finally, it showed
me that in spite of giving our all, sometimes things may not go as planned. And one just needs to learn
from one's mistakes and move on with the aim to create better results next time.</p>
