The current documentation is preliminary and will be updated with the final release of the PULSE-80 with final information.
Pulse-80 specifications have been defined, validated and qualified over -40°C to +71°C and in all conditions (thermal, vibrations, shocks and lifetime). The performance parameters presented in this document express typical (1 σ), and 3 sigmas specifications.
Each Pulse-80 Inertial Measurement Unit is carefully calibrated over the whole temperature range using a high precision two axis motion simulator (see knowledge center). The IMU performance is then validated after a resting period after the calibration, using several temperature points with a two axis rate table to ensure that no performance deviation is observed.
This rigorous manufacturing process guarantees consistent results over lifetime and in all environmental conditions. Advanced filtering techniques are also used to allow PULSE-80 sustains difficult vibrating environments.
The following specifications are applicable over the full temperature range -40 to 71°C and RH < 80% unless stated otherwise.
