Programming & Electronics ramblingsTrueFuse 2F: Measuring the Port Instead of Trusting It
The third part of the altitude fusion filter behind AltimeterCloud. A port coefficient measured rather than assumed, a slew witness taught to look both ways, an ejection charge that reads the wrong way up, and the same law ported into two firmwares that could not be built more…

Product UpdatesTrueFuse 2E: What Two Hundred Flights Taught Our Altimeter Fusion Filter
In August we explained why a barometer lies during a rocket flight and how TrueFuse 2C referees between it and the accelerometer. This is what happened next: two hundred and one real flights run through every candidate change, a new witness for the small ejection notches the old…

Programming & Electronics ramblingsTrueFuse 2C: How Our Model Rocket Altimeters Fuse Sensors for Accurate Altitude
Barometric pressure sensors are superb at rest, but a rocket flight attacks them: airflow over the static port during the burn, ejection charge spikes, transonic effects, even sunlight under the parachute. TrueFuse 2C is the sensor fusion filter behind AltimeterCloud and our…
