LV1b IMU Calibration Page

Here's our best guess to the linear calibration constants for the LV1b IMU:

Sensor

Calibration Equation

X

g's = (raw ADC) / (0.624 V/g * (6.025 V / 5 V) * (4096 counts/5 V))

Y

g's = (raw ADC) / (0.624 V/g * (6.025 V / 5 V) * (4096 counts/5 V))

Z

g's = (raw ADC) / (0.038 V/g * (6.025 V / 5 V) * (4096 counts/5 V))

Q

g's = (raw ADC) / (0.038 V/g * (6.025 V / 5 V) * (4096 counts/5 V))

Roll

°/s = (raw ADC) / (5 * 1.1628)

Pitch

Same as roll?

Yaw

Same as roll?

So, we built this IMU and it's cool... but what does it do? To find out, we did a calibration run on October 5, 2000 (prior to the 10/07/2000) launch. Although lacking in many ways, the analysis of the calibration data should be able to tell us:

Attached (see below) are the raw data and processed calibration data files.
