GPS Speedometer LC-8300A

The lineup of GPS speedometers has been renewed. The LC-8300A is the flagship model developed by our company, a pioneer of speedometers.
Our original IMU correction algorithm enables stable speed measurement regardless of the test environment,
even in urban areas where radio interference is likely to occur due to trees and buildings.
Equipped with various functions for the test that complies with regulations,
it supports a wide range of vehicle test.
With a compact body design and a simple configuration, you can test without a PC.
It is useful for a variety of measurement needs.
Feature
Stable measurement
- Achieve outstanding stability
- Improved satellite acquisition performance
Adopts a highly sensitive GPS/GLONASS receiver that is four times more sensitive than existing models. As a result, the satellite acquisition performance has been greatly improved, and there is no need to worry about satellite acquisition being interrupted during measurement. Also, the antenna can be installed inside the vehicle.
- GPS supported by IMU correction
By using not only the velocity information from GPS but also correcting by IMU, stable measurement is realized even in environments where radio wave reception is unstable.
In addition, even if the satellite acquisition condition is good, the velocity correction is constantly performed by the IMU. Thus. it is possible to output speed data very accurately compared to using GPS alone.

The above figure is an image of satellite acquisition and correction by IMU.
We do not guarantee the accuracy of our products or the number of satellites captured.
In addition, depending on the vehicle type and driving environment, the number of satellites captured may decrease and the measurement may become unstable.
- Expanding application scenes
- Expanding application scenes
Stable measurements can be performed without worrying about satellite loss, not only in open spaces such as test courses,
but also in urban areas where radio interference is likely to occur due to trees and buildings and under elevated roads.*
Also, when the vehicle is stopped, such as waiting at a traffic light, the speed display will stop at exactly 0 km/h.
* Depending on the driving environment, the number of satellites captured may decrease and the measurement may become unstable.
- For a wide range of test needs
The GPS antenna can be installed not only on the roof of the vehicle but also inside.* It can be used for a wide range of test needs, such as running resistance performance.


* Depending on the vehicle type and driving environment, the number of satellites captured may decrease and the measurement may become unstable.
For tests that require high distance accuracy and is sudden acceleration/deceleration, install the antenna on the roof.
- Perfect for such test scenes
Noise test
Not affected by wind noise
Coasting test
Air resistance does not increase
Actual driving test
Not conspicuous appearance
Test under bad weather*
Test in rain or snow
* The antenna has a protection class of IP67, thus it can be installed on the vehicle even in bad weather.
High response
- Even in sudden acceleration, sudden braking
High responsiveness is achieved by the correction function using IMU. Our original algorithm achieves both responsiveness, stability, and low noise. It is ideal for tests that require accuracy of transient response such as acceleration tests, braking tests, and steering stability.


Compact designed for on-board measurement
- Useful for various test vehicles
Space saving of about 60% by volume compared to the LC-8120 and reduced wiring that the IMU is built-in. Equipped storage function in the main unit, internal storage of main unit, it is possible to test with a simple configuration consisting only of the main unit and peripheral devices (Standalone Test Mode, PC-less). It can be used not only for four-wheeled vehicles, but also for vehicles with limited installation space, such as motorcycle, agricultural machinery, and construction machinery.

Palm size, compact and lightweight body
(LC-8300A GPS Speedometer)

Test results are recorded in the internal storage of the main unit
or USB memory (Standalone test mode)
* When it is difficult to attach horizontally the LC-8300A to a vehicle, the external IMU (optional) connection is also available.
Touch panel display
- Easy-to-use design
The display installed in the car is a LCD touch panel type. It is easy to see while driving and user-friendly UI.
