The FS106-A01 FOG Combined INS is a highly reliable, cost-effective navigation system with built-in receiver, widely applicable to navigation, control, and measurement in aircraft, unmanned vehicles, unmanned ships, and unmanned aerial vehicles.
This combined navigation system inherits the modular design philosophy of similar products, employing high-precision silicon optical gyroscopes and high-precision MEMS accelerometers. Through multi-sensor fusion algorithms, the main INS position and velocity from GPS are fed into the filter, while the INS position, velocity, and attitude also serve as filter inputs. The filter compares the differences between them to establish an error model for estimating INS errors, which are then used to correct the INS results, yielding combined navigation outputs for velocity, position, and attitude.
The inertial navigation system provides different configuration modes to suit various carriers, including airborne, vehicle-mounted, and shipboard applications. Vehicle-mounted mode includes vehicle constraint algorithms. Error estimation and correction enable long-duration high-precision navigation and positioning for carriers.
The FS106-A01 Series Combined Navigation System can be configured differently according to user requirements. Software functions configuration supports transfer alignment, combined navigation, pure INS computation, attitude and heading reference, maximizing satisfaction of diverse user requirements.
