So far we get, following the 3100 byte (that ends the “IRV-01” part):
Long duration counter: 001E : 30 => 7650 sec
Angular velocity x/y/z : 01F2 D1EC FF87 : 498, 53740, 65415 (1e-3 * deg/s?)
Magnetic field x/y/z: 2E17 038A 5C28 : 11799, 906, 23592 nT
IRVINE01 9k6 telemetry bursts
…. but too weak to decode
14:40 UTC no signals heard :-(
