1: The NRU performance may be subject to degradation caused by an improper installation.
2: The dynamic heading accuracy is specified with roll/pitch less than ± 45° and ROT ≤ 45°/s.
3: The LT-1000 NRU has an immunity filter against Iridium and Inmarsat transceivers
4: Solar radiation and environmental conditions will affect the measured air temperature
(accuracy is specified as on-board sensor performance)
