This product is a speedometer that measures the speed and vehicle behavior of automobiles, motorcycles, construction machinery, etc., using two signals: GPS/GLONASS satellite signals and XYZ acceleration signals from an inertial measurement unit (IMU). Thanks to the standard inclusion of a satellite receiver and inertial measurement unit (IMU), stable speed measurements are possible even in areas where satellite reception is poor, with high accuracy of within ±0.1 km/h.
In addition to measuring vehicle speed, the LC-8220 can measure 3-axis acceleration, angular velocity, and angle, as well as vector velocity that takes into account the direction of the vehicle (straight-line velocity is the velocity in the direction of travel, and its horizontal orthogonal component is the lateral velocity).
The LC-8120 is a standard model and does not offer vector velocity measurement, but it provides the same high-precision speed and distance measurement as the LC-8220. The LC-8120 can also be upgraded to the LC-8220 by adding optional features. New power-up options for the LC-8120 and LC-8220 include the LC-0855 high-precision IMU, the LC-0870 high-response IMU analog output, and the LC-0871 jerk measurement function, enabling high-precision vehicle behavior measurements such as those used in steering stability tests.
Using the LC-8220, you can perform tests such as handling stability tests and lane departure warning system tests, in addition to the conventional brake tests, acceleration tests, and coasting tests.
Features
Vector velocity measurement
It can recognize the direction of vehicle travel and measure straight-line speed and lateral speed.
High precision IMU
3-axis acceleration linearity ±0.1%, twice the precision of standard products.
High-response IMU analog output
3-axis acceleration and angular velocity are output as analog data with a 2 ms update cycle.
jerk measurement function
It is possible to measure, display, and record the differential values of acceleration in three axes.
White line detection function
The white line detection sensor allows for measurement start and stop triggers using a special reflective sheet installed on the ground.
Small, high-precision antenna
Adopts an antenna that is 1/40th the volume of conventional models - Can replace the antenna of the conventional LC-8200A model -
