Basecam GPS IMU V.1.0
GNSS-aided AHRS/IMU module
When all 6 positions are passed, system computes calibration values and emits a series of short pulses by
the green LED.
LED status indication
The multicolor LED signals the basic modes of operation by color:
Green — GNSS receiver is used in a solution. This is the main working mode when there is a
good reception of the GNSS signal.
Yellow — GNSS receiver is not used; device provides attitude and heading information without
the compensation of accelerations; position and velocity information is undefined.
Red — hardware fault, device is not operational
When a connection to the external host is established and device sends data, LED flashes 2 times per
second.
Service button
•
1 click
– calibrate gyroscope
•
2 clicks
– calibrate accelerometer (single position)
•
3 clicks
– calibrate magnetometer
•
long press
– if connected by USB, enter mass-storage device mode. Device appears as a USB disc
allowing to work with the content of the installed SD card. Functions that require access to the SD
card (like calibrations, data logging) will be unavailable in this mode.
General configuration parameters
General configuration parameters are located in the "CONFIG.INI" which you can find in the root directory
of the SD card.
