Low-cost integrated navigation system MEMS technology and satellite navigation
Low-cost integrated navigation system PA-GS/OEM product is a measurement device with high cost
performance based on MEMS technology and satellite navigation technology. It is widely used in navigation,
control and dynamic measurement. The system ensures the measurement accuracy through a number of
compensation technologies, and adopts strict production process to ensure that the product can accurately
measure the angular and linear motion parameters of the carrier in harsh environment.
Product features:
Wide range of application. With GPS/BD2 dual-mode satellite navigation system and high tracking sensitivity,
it is not only suitable for positioning and navigation in open areas, but also suitable for complex environments such as streets and jungles.
Strong adaptability. Silicon micro MEMS device, strong vibration and impact resistance, working at full temperature of -40 ℃ ~ + 60 ℃.
The performance index is excellent. The integrated navigation system has a horizontal attitude of 0.3 (RMS), a position better than 5 m (RMS), and a velocity
