Navigation Grade IMUs are electronic devices used for reliable and accurate orientation measurement in navigation applications. They differ from other types of IMUs, such as commercial-grade IMUs, in terms of accuracy, stability, reliability, and cost. Navigation Grade IMUs provide highly precise measurements of an object’s orientation, with low error rates, making them suitable for high precision applications. They offer stability over extended periods and are designed to withstand harsh environments. Compared to commercial-grade IMUs, Navigation Grade IMUs are more reliable but come at a higher cost. They find applications in the aerospace industry, autonomous vehicles, marine navigation, and military applications. Calibration techniques, including bias, scale factor, and misalignment calibration, are employed to maintain their accuracy. Navigation Grade IMUs can be integrated with other navigation systems like GPS, GNSS, and INS to enhance their performance. As technology advances, Navigation Grade IMUs will continue to play a crucial role in ensuring accurate and reliable orientation measurements for safe and efficient navigation.

China IMU80 Navigation Grade Imu widely used in unmanned vehicle

The typical IMU for unmanned vehicle use includes a three-axis accelerometer and three-axis rate sensor. The inertial measurement unit (IMU) is a device that directly measures a vehicle’s three linear acceleration components and three rotational rate components (and thus its six degrees of freedom). An IMU is unique among the sensors typically found in an unmanned vehicle because an IMU needs no connection to or knowledge of the external world. This environment independence makes the IMU a core technology for both safety and sensor-fusion. An accurate IMU can also determine and track attitude precisely. When driving, the direction or heading of the unmanned vehicle is as crucial as its position. Driving in a slightly wrong direction even briefly may put the unmanned vehicle in the wrong lane. Dynamic control of the unmanned vehicle requires sensors with dynamic response. An IMU does a nice job of tracking dynamic attitude and position changes accurately. Its fully environment-independent nature lets an IMU track position even in tricky scenarios such as slipping and skidding where tires lose traction. IMU80 IMU module provide reliable performance with good accuracy in dynamic environment, it has been widely used in unmanned vehicles by the Chinese leading companies, now more than hundreds of thousands IMU80 IMU modules are used in the unamend vehicles.

China IMU80 Navigation Grade Imu from supplier widely used in UAS Navigation & Control

UAV is unmanned aerial vehicle, commonly known as a drone, is an aircraft without a human pilot aboard. The flight of UAVs may operate with various degrees of autonomy: either under remote control by a human operator or autonomously by onboard computers. SkyMEMS IMU80 Inertial Measurement Unit is an industrial level IMU module, it can provide continuous acceleration and gyro angle for the UAV, which has been widely used in small UAV flight control.

China IMU80 Navigation Grade Imu manufacturer widely used in smart agriculture

Smart agriculture has changed the way farmers work their land. Real-time location information also allows farmers to maximize field utilization by avoiding missed or overlapping planting and harvesting efforts while minimizing time and fuel usage through optimized travel. Such systems can also provide semi-autonomous piloting of farm machinery to reduce driver fatigue and allow efficient operation even in low visibility conditions such as dust, fog, rain, and darkness. Currently more than 50% of farmland, great and small in extent, now utilizes smart agriculture methods with adoption continually increasing. Because they can accurately measure the movement of objects in three dimensions, IMU modules are essential to modern society. They are utilized in many more applications than just the automatic control and autonomous driving on tractors and other agricultural machinery used for precision agriculture. Examples include orientation measurement during autonomous driving, drone orientation control, camera and antenna vibration detection and control, and controlling the angle and attitude of blades and arms on construction and mining equipment. The high-precision detection of tiny changes in movement, which are too small for the human eye to detect, makes IMUs vital to high-precision data measurement and control of machinery. SkyMEMS’s IMU modules use high-performance MEMS sensors that features excellent stability, low power consumption and low noise characteristics.. And their linearity characteristics enable high-precision measurement of various kinds of movement over a wide range from slow to fast. This allows them to be used in a broad array of smart agriculture applications.

Q: What is IMU80’s g-sensitivity parameter?

A: it is 0.1dps/g

Q: What is shocking resistance of IMU80?

A: it is 2000g, <1ms, with power or power off.

Q: How to keep IMU80 bias calibration good after time? What a procedure?

A: In fact, before we do the high and low temperature compensation and turntable calibration, we have done ESS in the high and low temperature box for 48 hours to release the environmental stress and ensure that the stress deformation is as small as possible. But after a long time, 10 months or a year later, due to the characteristics of the MEMS sensor itself, the performance may have little change. At this time, if the customer has high accuracy requirement, they can return to our factory for calibration again.

Q: if turning off the fusion algorithm that IMU80 itself has, can be the output frequency of IMU80 up to 500Hz?

A: we have done 400Hz before, for 500Hz, theoretically IMU80 can.

Q: What is IMU80 working temperature?

A: The test temperature is -40 to 85 °, and the actual temperature may exceed 85 ° when testing high temperature. Actually, during the test, we kept IMU80 stay at both -40° and 85° for an hour

Q: What is IMU80’s sampling frequency of raw inertial measurements?

A: 1Khz Q: Whether IMU80 support raw 1k frequency data output?

A: no, IMU80 doesn’t support direct 1k frequency raw data output, IMU80 needs to do the data processing for the raw data.

Q: How about IMU80’s bandpass filter?

A: IMU80 has 3rd order low pass filter inside, and the cutoff frequency can be set by the IMU80 management software. And the low pass cutoff frequency should be set according to the actual application. And the low pass filter is mainly used to filter some high-frequency noise interference. Customers need to test the interfering signal frequencies in their own environment and then set the cutoff frequency. If the settings are wrong, the data will be worse. For example, if the IMU80 is used in the vehicle, we suggest that set the cutoff frequency into 25Hz for accelerometer, 30Hz for gyro, and test it at your side. And to get better performance, please contact with us and let us know your application, so that we can recommend our solution for you. Usually first analyze the test data, and test the frequency spectrum, then set the parameter, and then test again to do the best settings.

Q: How about the delivery time?

A: for our standard model, if we have them in stock, only need 2~3days to re-test before shipping, if it is out of stock, then need around 2 weeks to arrange the production and tests. For the ODM electronic product, if needing to modify the structure, it will need around 3~4 weeks to arrange the production and tests.

Q: How to arrange the payment?

A: about the payment, please pay to our company account, the beneficiary’s name: NANJING SKY MEMS TECHNOLOGY CO., LTD.  And our email is only to contact with u formally. To notice this to avoid the loss.
