RTK signal is easily blocked? IMU makes RTK have unlimited possibilities

When you use an RTK surveying instrument to measure in some places with obstructions or requiring a large tilt, do you always encounter weak signals, no signals, or inaccurate measurements?

Now many RTKs are equipped with IMUs to make measurements more efficient and accurate. IMUs can maintain short-term relative positioning accuracy when RTK signals are blocked or temporarily ineffective. A separate external IMU can meet measurement needs more flexibly.

For example, an IMU ER-MIMU-12 can perfectly solve the above problems while improving measurement and stakeout efficiency!

**Excellent performance, automatic tilt compensation**

Equipped with a three-axis gyroscope and a three-axis accelerometer, the built-in gyroscope dynamic measurement range is ±400°/s, bias instability ≤1°/h, angle random walk <0.25°/√h; accelerometer dynamic The measurement range is ±30g and the bias stability is <50ug.

The IMU can be used to perform real-time interference-free and automatic tilt compensation on the RTK surveying instrument, and can perform measurements at large tilt angles. The IMU data is used to sense the device’s attitude changes (roll angle, pitch angle, and yaw angle) and perform tilt compensation.

It can ignore magnetic fields and can achieve accurate measurements even in difficult locations.

**Compact size, easy integration**

The 120mm x Φ30mm cylindrical IMU weighs ≤150g and is very portable.

In some measurement scenarios that require rapid deployment, the cylindrical IMU can be conveniently fixed on a tripod or measuring rod and can be put into use quickly without complicated debugging, saving time and costs.

**Quick initialization and accurate dynamic measurement**

RTK initialization time is long, IMU can significantly shorten the RTK initialization time. You can initialize the internal IMU by walking a few meters and easily start the measurement mode!

Even if the measuring rod is moved, tilted or leveled during measurement, there is no need for tedious calibration procedures and the measurement can be continued immediately while ensuring measurement accuracy.

IMU can make RTK measurement results more accurate, improve measurement efficiency, and expand the application scope of RTK surveying instruments, especially in environments with limited GNSS signals.

The integrated navigation: escorting safe flight of drones

 The integrated navigation: escorting safe flight of drones

GNSS systems (such as GPS, GLONASS, BDS, etc.) provide positioning services with global coverage, but the signals may be blocked or interfered with. They are usually combined with inertial navigation systems to form the integrated navigation system, which can be used in various unmanned systems.

At present, integrated navigation has been widely used in UAVs. It can perform positioning and orientation, and provide attitude, heading and altitude information to the flight control system of the UAV.

The flight control system combines other sensor information to achieve automatic flight, and can also use the combined attitude information to achieve fuselage attitude stability.

We have an integrated navigation system ER-GNSS/MINS-05, which is the most cost-effective one. It has high reliability and is reasonably priced.

1. The product has highly reliable and low-cost MEMS gyroscopes (bias instability <2°/h) and accelerometers (bias instability <24ug).

2. The integrated navigation information provided has roll and pitch accuracy up to 0.1°, post-processing 0.03°, heading 0.1°, post-processing 0.05°, and speed accuracy up to 0.03m/s.

3. Built-in full-band full-system dual-antenna positioning and orientation GNSS module. Single antenna can perform high-precision positioning and speed measurement. Dual antennas can be quickly oriented and can provide high-precision heading and attitude information, which is crucial for applications such as drones and ship navigation.

4. It also has a variety of data interfaces, easy installation, and supports RS422/RS232 and CAN. It is sufficient to meet applications in most cases.

Choose a suitable IMU to make your drone flight more stable and safe

 

       As one of the core components of drones, IMU plays an irreplaceable role. Its high precision, fast response and freedom from external interference enable drones to maintain stable and precise flight and accurate navigation and positioning in complex environments, and can also perform fault diagnosis for drones. ERICCO's MEMS IMU can achieve high performance while being small in size and light in weight, making it very suitable for drones.

We have a tactical-grade IMU ER-MIMU-M02, which is low-cost and has an advantage in price. It is a 10-axis IMU with an added three-axis magnetometer and barometer (altimeter). It is only 47×44×14mm in size and weighs 50g. Compared with other IMUs, it is more suitable for drones.

The built-in accelerometer of the IMU cannot be used to detect absolute heading (yaw). The magnetometer in this IMU measures the magnetic field strength in three dimensions, which can help determine the heading of the object as well as roll and pitch, and correct the integrated error of the yaw gyroscope in the sensor fusion algorithm.

The barometer measures the atmospheric pressure and calculates the altitude of the drone, which is crucial for the safe flight of the drone!

The dynamic measurement range of the built-in gyroscope is ±450º/s, the bias instability is 2 º/h, and the angular random walk is 0.08º/√h. The dynamic measurement range of the accelerometer is 16g, the bias stability is 0.1mg (Allen variance), and the angular random walk is 0.02m/s√h.

Considering the flight time requirements of drones, this IMU has a power of only 1.5W, which can extend the flight time of drones.

This IMU has a short production cycle and can be mass-produced, which is particularly suitable for users with large demands and limited budgets.

Do you know what can make drone flights more stable, safer and more widely used?

The key to achieving autonomous navigation, stable control and precise flight of drones is closely related to IMU, which is one of the core technologies of drone systems. At present, there are also research teams that have developed IMU-centric data-driven diagnostic methods to perform fault diagnosis on drones without the need for additional sensors. Choosing the right IMU can make flight more stable and safer.

ERICCO's MEMS IMU ER-MIMU-07 and ER-MIMU-03 (OEM customization is available) can be used in drones. Using MEMS technology, they are small in size, superior in performance, light in weight, low in power consumption, and cost-effective, and are very popular among users.

Drones have strict requirements on the size and weight of IMUs. The ER-MIMU-03 has a size of (43.2×43.2×35.5mm (without shell), 65×70×45.5mm (with shell)) and a weight of (≤100g (without shell), ≤220g (with shell)).

The ER-MIMU-07 is a very small IMU, measuring only 38.6 x 44.8 x25.5mm and weighing less than 70g, which is suitable for drones with higher IMU requirements.

Flight control of drones is one of their most basic functions. MEMS IMU helps drones maintain a stable attitude by providing real-time acceleration and angular velocity data.

The gyroscope measurement range of ER-MIMU-03 and ER-MIMU-07 is ±400deg/s, bias instability <0.3deg/hr, angular velocity random walk <0.15°/√h, accelerometer bias repeatability 5mg, and second-order nonlinear coefficient <100μg/g2. At the same time, it has the characteristics of low power consumption, which prolongs the flight time of drones.

It can also combine data from other sensors (such as GPS, magnetometer, etc.) to calculate the precise location and attitude information of the drone for navigation and positioning. When the drone is taking aerial photos, it can maintain extremely high stability to ensure the clarity and stability of the images and videos taken. At the same time, it can also be used as part of the drone's fault safety system to detect abnormal movements or attitude changes and trigger automatic recovery procedures or emergency landing procedures to protect the safety of the drone and the surrounding environment.

In the design and application of drones, high-performance IMUs are able to provide stable and accurate data under various environmental conditions, such as temperature changes, vibrations, and rapid movements, and perform precise tasks such as aerial photography, logistics transportation, and agricultural monitoring.

MEMS IMU has many applications in the field of drones. They not only improve the performance and stability of drones, but also expand the scope of application of drones.
