Hardware description
Overview
The AV200 is a miniature GNSS-aided inertial navigation system. It combines dual multi-constellation,
multi-frequency RTK GNSS receivers with a tactical-grade quad IMU array to provide a compact
centimetre-level navigation solution. Additionally, the system includes 32 GB data storage and an on-
board processor running the real-time strapdown navigator and Kalman filter.
The dual receiver integration allows greater heading accuracy with wider antenna baselines and
ensures stable heading performance even when stationary and during low dynamics. The custom built
quad IMU array consists of four individual IMU sensors that each combine 6-axis MEMS gyros and
accelerometers, providing improved performance and redundancy. The sensor fusion between the
GNSS receivers and inertial sensors is done seamlessly in real-time for a continuous 100 Hz navigation
output. Data is automatically logged to the 32 GB eMMC for added data protection.
Figure 1 and Figure 2 show the key points of note on the AV200. The numbered labels are described
in Table 3.
