VBOX IISX can provide three sampling rates: 5Hz, 10Hz, and 20Hz, all of which have a built-in display screen that can store data through an SD card. They all have functions such as high-speed brake trigger input, CAN bus interface, two analog and digital output, USB and serial interface, etc. The VBOX IISX data recorder has the highest independent positioning accuracy among a series of products, and can achieve a positioning accuracy of<1m even without using a base station by using the free WAAS/EGNOS calibration service. The dual antenna (SL) version is equipped with a second GPS engine, which means it can measure sideslip and pitch angles.
