Inertial Measurement Unit (IMU)¶
DID_IMU¶
Inertial measurement unit data down-sampled from IMU rate (DID_FLASH_CONFIG.startupImuDtMs (1KHz)) to navigation update rate (DID_FLASH_CONFIG.startupNavDtMs) as an anti-aliasing filter to reduce noise and preserve accuracy. Minimum data period is DID_FLASH_CONFIG.startupNavDtMs (1KHz max).

|---|---|---|
| time | double | Time since boot up in seconds. Convert to GPS time of week by adding gps.towOffset |
| status | uint32_t | IMU Status (eImuStatus) |
| I | imus_t | Inertial Measurement Unit (IMU) |
DID_IMU_RAW¶
IMU data averaged from DID_IMU3_RAW. Use this IMU data for output data rates faster than DID_FLASH_CONFIG.startupNavDtMs. Otherwise we recommend use of DID_IMU or DID_PIMU as they are oversampled and contain less noise.
imu_t
| Field | Type | Description |
|---|---|---|
| time | double | Time since boot up in seconds. Convert to GPS time of week by adding gps.towOffset |
| status | uint32_t | IMU Status (eImuStatus) |
| I | imus_t | Inertial Measurement Unit (IMU) |
DID_PIMU¶
Preintegrated IMU (a.k.a. Coning and Sculling integral) in body/IMU frame. Updated at IMU rate. Also know as delta theta delta velocity, or preintegrated IMU (PIMU). For clarification, the name "Preintegrated IMU" or "PIMU" throughout our User Manual. This data is integrated from the IMU data at the IMU update rate (startupImuDtMs, default 1ms). The PIMU integration period (dt) and INS NAV update data period are the same. DID_FLASH_CONFIG.startupNavDtMs sets the NAV output period at startup. The minimum NAV update and output periods are found here: https://docs.inertialsense.com/user-manual/application-config/imu_ins_gnss_configuration/#navigation-update-and-output-periods. If a faster output data rate for IMU is desired, DID_IMU_RAW can be used instead. PIMU data acts as a form of compression, adding the benefit of higher integration rates for slower output data rates, preserving the IMU data without adding filter delay and addresses antialiasing. It is most effective for systems that have higher dynamics and lower communications data rates. The minimum data period is DID_FLASH_CONFIG.startupImuDtMs or 4, whichever is larger (250Hz max). The PIMU value can be converted to IMU by dividing PIMU by dt (i.e. IMU = PIMU / dt)
