The micro inertial navigation system (INS) is a self-contained navigation approach that tracks the position and orientation of an item in relation to a specified starting point, orientation, and velocity using readings provided by accelerometers and gyroscopes.
Three orthogonal rate-gyroscopes and three orthogonal accelerometers, which measure angular velocity and linear acceleration, respectively, are generally found in INS.
It is possible to track the position and orientation of a robot on which the INS device is installed by processing signals from these devices.
The Global Micro Inertial Navigation System market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Quanta Micro INS is launched by SBG Systems. In a small package, the miniaturized inertial sensor integrates a high-performance IMU and a dual frequency/quad constellations GNSS receiver for centimetric position, according to a news release.
50 x 37 x 23 mm and 38 g describe the RTK-capable sensor. It provides roll/pitch with an error of less than 0.02° and heading with an error of less than 0.06°.
Despite having a compact design, the sensor incorporates all the functionality found in other SBG inertial sensors, such as an integrated data logger, Ethernet connectivity, a PTP server, numerous serial interfaces, and a CAN connector. It’s simple to configure thanks to a built-in, approachable web configuration interface.
Additionally, the sensor can be set up via the SBG API or ROS drivers. The Quanta Micro can retain excellent heading performance with a single antenna while simultaneously supporting dual GNSS Antenna mode to improve heading accuracy in low dynamic situations. Qinertia, a Post-Processing Kinematic (PPK) tool from SBG, can be used to post-process data that was captured with the sensor.
Due to the strong coupling of GNSS and inertial data processing made possible by this, centimeter-level precision can be maintained even during prolonged GNSS outages by merging forward and backward solutions. Additionally, it reduces roll/pitch errors to less than 0.015° and heading errors to less than 0.035°.
Large and bulky, with volumes ranging from 330 in3 to 540 in3, weights between 13 and 22 pounds, and power needs between 25 and 38 watts, are typical RLG and FOG systems.
These systems include GPS-assisted inertial navigation systems (INS), inertial measurement units (IMUs), Attitude Heading Reference Systems (AHRS), and miniature MEMS sensors.
The Encore-Orion EN-2000 MINAV is a three-axis design that combines new Field Programmable Gate Array (FPGA) electronics with the company’s proprietary next-generation solid-state optical transceiver with advanced integrated optics to deliver stand-alone aircraft grade navigator performance at a third of the SWAP of competing or legacy systems.
There are two standard versions of the EN-2000 model: one with an IMU and the other with a freestanding INS configuration. Without the need for a GPS receiver, the INS version can retain positional accuracy close to GPS level and gyrocompass to less than 0.7 milliradians. It is therefore perfect to use in locations where GPS is prohibited. The device can also be used with an external GPS for situations where it is necessary, giving users even more freedom.
Vector Nav has offered cutting-edge embedded navigation solutions that are optimized for SWAP-C (size, weight, power, and cost) limitations to systems integrators in the robotics, aircraft, military, and maritime industries. Bringing the most cutting-edge and inventive solutions to a wide range of challenging and complicated industrial and military applications.
Vector Nav has a solid history in aerospace systems and expertise developing and testing spacecraft, launch vehicles, and micro-aerial vehicles. The potential of future technologies is increased by Vector Nav’s application of high-performance filtering and calibration techniques from the aerospace industry to the field of inexpensive, high-quality industrial grade MEMS sensors and GPS/GNSS technology.
This new INS-U version from Inertial Labs enables Pixhawk Autopilot to guide UAVs in an environment where GNSS is prohibited for an extended period of time (more than an hour) by providing fused (GNSS + IMU) NMEA data. GPS-Aided Inertial Navigation and Measurement Units are developed by Inertial Labs.
Position, velocity, and absolute orientation (Heading, Pitch, and Roll) of any mounted device are all determined by the INS-U, a fully integrated, high-performance strapdown system that combines the Inertial Navigation System (INS), Attitude & Heading Reference System (AHRS), and Air Data Computer (ADC). For both static and highly dynamic applications, horizontal and vertical position, velocity, and orientation may be measured with great accuracy.
