Hexstar / DIY satellite kit

DIY satellite kit: build your own satellite, in class.

A DIY satellite kit turns space science into something students can hold. They assemble a small CubeSat, program it, and watch its data arrive live on a laptop, then take it outside or send it up on a balloon. Here is what students learn, how schools run it, and which kit fits which class.

What students learn with a DIY satellite kit

Electronics

How a satellite is wired

Power, sensors, the flight computer and the radio, and how they share one bus.

Coding

Arduino programming

Reading sensors, packing telemetry and sending it on a schedule.

Physics

The atmosphere, measured

How pressure, temperature and altitude change as the satellite climbs.

Radio

Talking to the ground

Antennas, range and why spacecraft send small, regular packets.

Data

Analysing a mission

Plotting live telemetry and comparing it with predictions.

Teamwork

Systems engineering

Students split into power, payload, comms and ground teams, like a real mission.

How schools use a satellite kit

  1. Introduce the mission.What CubeSats are, why they are 10 cm cubes, and what this class’s satellite will measure.
  2. Build in teams.With plug-in modules there is no soldering, so a group can assemble and power up a Hexstar Gen 1 in one lesson.
  3. Code and test.Students upload code from the Arduino IDE and see sensor readings appear on the ground-station dashboard, ready to project for the whole class.
  4. Go outside.A playground or rooftop range test shows how radio links work and how far the data reaches.
  5. Launch (optional).Older groups can fly Gen 2 under a high-altitude balloon, track it by GPS and recover it after the parachute descent.

Hexstar also runs CubeSat workshops and balloon launches with schools and universities, and offers a 10-week curriculum with the Classroom pack.

Ages are a guide: younger students can build Gen 1 with a teacher, and keen makers of any age can take on Gen 2 or the 1U.

Used around the world

Hexstar satellite kits are built in Kolkata and are used in more than 80 countries on six continents, by teams at the University of Oxford Physics Laboratory, MIT, Apple, NAVER, ISRO, IIT Kharagpur, IIT Madras, EPFL Space Center, Michigan Tech, the University of Athens, the Bahrain Space Agency and Paras Defence.

Frequently asked questions

What is the best DIY satellite kit for students?

For a first class project, a no-solder kit with its own ground station works best. Hexstar Gen 1 is built for classrooms; Gen 2 adds GPS and long-range LoRa for older students and balloon flights.

What age is a satellite kit suitable for?

Hexstar Gen 1 suits students from about 12 years with a teacher. Gen 2 suits senior school and college students, and the Hexstar 1U is aimed at universities and advanced makers.

Do schools get a discount on satellite kits?

Yes. Schools and bulk orders can ask for a custom quote through the enquiry form or WhatsApp at +91 93306 04060.

Can students launch the satellite?

Yes, under a high-altitude balloon with a parachute and a recovery plan, following local aviation rules. Gen 2 has GPS and LoRa so it can be tracked to around 30 km and recovered.

Is a DIY satellite kit the same as a real satellite?

It uses the same subsystems and 1U size as a real CubeSat, so students learn how satellites work, but it is an educational kit and is not certified for orbital launch.

Start your mission

Gen 1 and Gen 2 are in stock and ship from Kolkata to India and worldwide. Gen 3, our flagship 1U CubeSat with three stacked flight boards, is open for pre-order. Schools and bulk orders get a custom quote.

Educational use only. Hexstar CubeSat kits are made for learning and educational experiments. They are not certified or intended for real spaceflight or orbital launch. High-altitude balloon launches are entirely at your own risk, and you are responsible for following local aviation and radio rules.
