Third party device
This log was uploaded from a Zeta Rocketry Zeta II, a non AltimeterCloud device.
⚠The accelerometer reached the limit of its 16 G range for 100 ms during the burn, so the peak acceleration, thrust and impulse here may read low.

⚠The accelerometer reached the limit of its 16 G range for 100 ms during the burn, so the peak acceleration, thrust and impulse here may read low.
⚠This altimeter has no gyroscope, so full accuracy may be impacted in our impulse and drag calculations: the speed the drag is worked out from comes from pressure alone, where an altimeter with a gyroscope gives a fused speed.
With no loaded weight the impulse would only give the motor’s rating back, so it waits for the weight. The burn time is measured either way.

The log

Other makes of altimeter keep their settings on the device and do not write them into the log, so there are none to show here. This is what the file itself told us.

Getting logs off the Zeta Rocketry Zeta II
Read the flight off the altimeter with ZetaPost and upload the .zta file it saves. It carries the raw pressure and all three accelerometer axes, so the altitude, burnout and thrust are worked out here. The logs we have each hold 36 seconds, so a long descent may end in the log before it lands.

Files

Where the altimeter signs its log, the file carries that signature and a tick beside it. A tick means the data is unchanged since the device wrote it, which is what a record claim needs.

The log recomputed for your own sea-level pressure and temperature. Columns: time, altitude as recorded and adjusted, raw altitude as recorded and adjusted, pressure.

This file is built here from the signed log, so it carries no signature of its own. Anyone verifying a claim should be sent to the flight page and build their own from the original.

One row for every time any chosen data set has a sample. A data set with no sample at that time is left blank rather than filled in. Built from the chart’s data, so it carries no signature.
