MEMS inertial navigation system

ER-MGI210 / 230 Closely integrated navigation system

ER-MGI210/230 Closely integrated navigation system can provide horizontal attitude, Heading attitude and other information, longitude, latitude, altitude, etc. positioning information, and the 3D acceleration, angular velocity inertial measurement information; and by extending the range of the mileage meter and the height of the barometer to further improve the accuracy and applicability of the system, can be widely used in unmanned aerial vehicles, vehicle navigation, aviation and platform stability control and other fields.

ER-MGI230 use with high accuracy and high dynamic GPS receiver as the satellite signal sensor, using carrier phase differential technique and fast calculation of the whole week ambiguity technology, can accurately calculate the azimuth angle of the carrier motion; and inertial measurement technology aided attitude determination navigation, when the GPS signal is interference, by maintaining the inertial measurement unit, within a period of time, system can still output high precision data.

ER-MGI230 overcomes the deficiency of a single device, give full play to the GPS high precision, no accumulation error, no drift, low price and inertial products good dynamic performance, strong anti-interference ability, without the need of external signal source are able to work and Improve the overall attitude measurement accuracy, navigation accuracy and real-time tracking performance of the system. The proof in the land, sea and air a variety of environmental test, heading accuracy of 0.1 degrees, roll and pitch accuracy 0.05 degrees, and effectively overcome the drift angle of heading error, it is multi system compatible and complement each other, mutual backup all-weather high reliability azimuth measurement products.Especially for In satellite communication vehicle, meteorological radar vehicle, warship, expedition ship, airship, UAV, fire control system, command and control system, weapon aiming system, have very strong competitiveness.
