MH-LP212A
High PerformanceInertial Navigation System
The state-of-the-art
LP212A was designed as a small and lightweight Navigation System for market. Featuring a Monolithic Ring Laser Gyro (MRLG) and an accelerometer
triad, LP212A inertial sensors are tightly coupled with GPS/BDII to give
best performance in its class at a consumer price.This latest instrumentcan
beoperatedin continuous mode at
a high speed while simultaneously sending data to the surface equipment. Long life assured, it is utilized in numerous applications,
especially in vehicles with bad shock environment. LP212A unit can be
integrated with our standard CDU (Central Display Unit) and PNU that can be
used both in laboratories and outside, thus ensuring information collection,
monitoring, processing between this navigation system and other related
devices.
LP212A
MAIN FEATURES AND CAPABILITIES
LP212A is characterized by
high-precision inertial, strong shock resistance ability,
and usually applied to large mobile environment.
With strong shock
resistance ability, this advanced device can protect against more than 400g
impact force instantaneously.
With perfect integrated
navigation function, LP212A is tightly coupled with GPS/BDII and provides the
best navigation with an automatic selection of optimal choices according to
vehicle environment.
LP212A has the best
adaptive design, and can access to various communication interfaces (RS232、RS422、CAN).
LP212A
MAIN APPLICATIONS
LP212A
offers a low-cost, low-weight, navigation solution to a wide variety of
vehicles, especially in bad shock environment.
