Basecam GPS IMU V.1.0
GNSS-aided AHRS/IMU module
Features
•
Integrated GNSS-antenna for a compact size
•
Full set of navigation sensors: 3-axis
gyroscope, 3-axis accelerometer, 3-axis
magnetometer, barometer (altimeter), GNSS
receiver (concurrent Galileo, GLONASS,
GPS / QZSS)
•
Powerful MCU running UKF for a sensor
fusion at high rates
•
Thermal stabilization helps to keep high
precision with the change of environmental
temperatures
•
Interfaces: UART, USB, CAN*, I2C*
•
Onboard SD card for a high-rate data
logging with the actual date-time
information and flexible set of data to log
•
Backup battery for a GNSS "warm start"
mode and real-time clock
•
Open serial API protocol allows using this
sensor in various applications
•
Compatible with all versions of the
SimpleBGC32 controllers**
•
Functionality will be constantly improved
by the firmware updates
•
Cost-effective solution compared to other
GNSS-enabled solutions on the market
* CAN and I2C interfaces will be implemented in future
releases of the firmware
** For full support of all functions of the Basecam GPS IMU, it's
required to update the main controller's firmware to the
version 2.68b7 and above.
Overview
The
Basecam GPS IMU
is an GNSS-aided
compact AHRS/IMU module developed by
Basecamelectronics company to work as an
external IMU sensor* with all versions of
SimpleBGC32 controllers. It has much better
precision compared to the internal IMU sensor,
that allows improving precision of stabilization
in demanding applications, where the regular
IMU sensor does not work reliably.
GPS IMU connects to any free UART port of the
main controller and provides precise attitude
and heading information, that can be used as a
reference to correct the internal IMU sensor,
solving its common problems: gyroscope drift,
an affection of linear accelerations, drift caused
by the changes in environmental temperature.
*Note that currently GPS IMU module does not replace the
regular IMU sensor, though this functionality may be
implemented in future.
