Fields of a D frame
Field	Unit	Meaning	Accepted
`t_ms`	ms	Rocket clock since power-on	0 – 4294967295
`accZ`	m/s²	Acceleration along the rocket (MPU6050)	±200
`height`	m	Height above the start point (BMP280)	−1000 – 100000
`velZ`	m/s	Vertical speed, integrated from acceleration	±1000
`pitch`	°	Tilt away from the Z axis	±180

DATA frames (the older format) add roll, yaw and temperature but carry no rocket clock, so they are timed by when they arrive. Accepted: accZ ±50 m/s², height −100 – 10000 m.

Charts use t_ms as the time axis. Late frames are put back in order, and the charts wait a short, self-adjusting window so they can land in place.
