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
Application fields and application modes:
Land use, navigation, drones, and can also be extended to other
applications.
