KsINS-90L type laser strapdown inertial navigation system
product description:
The KsINS-90L -type inertial navigation system is a standard high-precision laser strapdown inertial navigation system. It has the advantages of small size, light weight, high precision, and good reliability. It can meet the needs of long-term autonomous navigation in complex environments and is suitable for In various short-term navigation, integrated navigation, guidance and control and other fields. The heading alignment accuracy is better than ≤0.3mil (1σ), and the pure inertial navigation accuracy is better than 0.5nmile/h (CEP). The system can integrate satellite, radio, barometric altimeter, Doppler, odometer and other information to achieve high-precision integrated navigation.
Features:
● 15kg lightweight high-precision laser strapdown product, 40% cheaper than traditional products
●Using domestic high-precision spatial three-axis laser gyroscope and quartz flexible accelerometer
●Space three-axis laser gyroscope bias stability is better than 0.001°/h (1σ)
●Accelerometer bias stability is better than 30μg (1σ)
●Achieve static and dynamic base alignment, and can choose self-alignment, on-the-fly alignment or transfer alignment according to user needs
●It can be integrated with various information such as satellites, odometers, altimeters, star sensors, etc. for combined navigation, and the interface has strong scalability
