A web page I built to replay rocket flights on a map or in a 3D view. It shows each rocket's track, altitude, and speed, and marks liftoff, apogee, and landing as they happen. For now it plays one simulated flight, made by running my GPS and radio board's firmware on a PC.

Here's what I'm building now and what comes next. A full write-up is on the way.
In progress
I'm building a receiver that picks up live data radioed down from our team's rockets during flight. It decodes the data and sends it over Bluetooth to a laptop or phone, so we can track the rockets in real time. Right now I'm choosing the radio parts and antenna, designing the circuit board in KiCad, and writing the code that receives the data.
Up next
Next I want the Flight Console to follow a rocket live during a launch, using the data my ground station receives. That part has to wait until the ground station is finished. For now it replays one simulated flight, so you can open it and see what I have so far.
I'm Christopher Sparrow, an electrical engineering student at Northeastern. Most of the work on this site comes from my contributions to AerospaceNU, Northeastern University's rocketry club. I'm on the avionics subteam, which designs the electronics for club projects like air brakes (flaps that slow the rocket down) and our supersonic carbon fiber rocket.
In fall 2025 I worked with mentors on our flight computer's code. Now I'm building two projects on my own. The first is a circuit board built to track the rocket with GPS and radio its position down to the ground. I've already designed the board, and right now I'm assembling it. The second is a ground station, a radio board that will pick up the rocket's data during flight and send it over Bluetooth to a laptop or phone.
Dogtooth Systems is named after the dogtooth tuna, and its logo is on circuit boards I've designed and across this site. Some of my deepest passions are freediving and spearfishing, and a lot of spearos have heard stories about the dogtooth being the hardest fish to target. Going after one tests your skill, patience, gear, and how well you know the sport.
I try to bring that same mindset to engineering. With rocket electronics, most of the work happens on the bench long before launch day, and everything has to come together the one time it really matters.
I'm looking for a spring or summer 2027 co-op in hardware, avionics, embedded systems, or radio work.
I'm looking for a spring or summer 2027 co-op, and I'm always happy to talk about projects. Email is the fastest way to reach me.
