The unveiling of the INS began in 2001 when Inertial Labs began manufacturing it’s first MEMS based, IP-67 sealed (later releasing OEM Navigation System versions), MIL-STD-810G qualified, multiple interfaces and COM ports Single and Dual Antenna GPS-Aided Inertial Navigation Systems (INS). Each INS contains an Inertial Labs developed Tactical or Industrial-grade Inertial Measurement Units (IMU) and reliable single or dual GNSS receiver from suppliers like Novatel, Hemisphere, and Ublox.
The professional model of INS, the INS-P utilizes an embedded, high-precision, gyro-compensated magnetic compass, which allows the navigation system to measure and output high precision Heading without GNSS signal even in extreme environmental conditions (temperature, vibration, interference from external magnetic field).
Sometimes called a 3D laser scanner, LiDAR is a surveying method that measures distance to a target by illuminating the target with pulsed laser light and measuring the reflected pulses with a sensor. It has terrestrial, airborne, and mobile applications. Some models of 3D LiDAR are able to generate up to 700,000 data points per second, There are plenty of exceptional producers on the market, for example Quanergy®(2) and Velodyne®.
Perhaps area mapping is still the biggest domain for remote sensing. Making sense of the physical world by analyzing maps and 3D models allows businesses to make faster and more informed decisions that increase efficiency, profit and more importantly, improve safety. Few of the most often used bases it can be done on are a land vehicle or Unmanned Aerial Vehicles (UAV).
Disaster response and mitigation is an increasingly successful market for autopilot suppliers. The INS has been consistently used with Unmanned Aerial Vehicles in both GPS enabled or GPS-Denied environments. Whether they are putting out forest fires or identifying and responding to personnel in critical condition, the Veronte Autopilot (integrated Inertial Labs INS-P solution) can handle long mission profiles while carrying large payloads in GNSS-denied environments.
The Inertial Navigation System is the most robust navigation sensor on the market. Use the INS as an independent navigation sensor, or easily integrate with other sensors that the INS has been adapted for such as: LiDAR’s, Doppler Radar, Stereo Cameras, Echosounders, and many more. These useful integrations allow for a robust solution for even the most difficult-to-navigate urban environments.
Inertial Labs recently released an improved navigation algorithm that increases navigational accuracy for Ground Vehicles in GNSS-Denied environments. This “Tunnel Guide” feature has been proven through trials and testing to result in a position accuracy of 0.2% over Distance Travelled (DT) in GNSS-denied environments. Data also supports that with the injection of aiding information from other onboard sensors such as an odometer, airspeed sensor, or wind speed sensor, the Inertial Navigation System can produce position accuracy as low as 0.05% over DT.
Precision Agriculture, an industry on the rise for Autonomous Ground Vehicles is one of the most used cases of autonomy in this century. Recent reports show that by the year 2025, Precision Agriculture is expected to grow to become a 43.4-billion-dollar industry worldwide. For an industry that didn’t begin gaining traction until the 1990’s, it’s quite an impressive market. The INS-DL and INS-D have been a popular solution for AGVs both in the industrial and military sector for their exceptional navigation performance.
ROV’s are an ideal platform for the INS. These platforms have taken advantage of the advanced MEMS-based navigation features of the Inertial Labs INS. Until recently, this market was only accessible for Fiber Optic Gyroscope-based (FOG) inertial sensors. However, with improved calibration procedures and methods for precision machining being utilized between MEMS-sensitive elements, the Inertial Labs INS now has the ability to compete with FOG units in both performance and reliability.
The Inertial Labs Inertial Navigation System has been designed to be compatible with a number of different solutions. Autopilot platforms such as Pixhawk or Veronte by Embention (distributed by Northwest UAV) give users precision accuracy at a fraction of the cost, plus the added functionality of each individual system.
Custom output formats support users the ability to communicate directly with the Cobham Aviator UAV 200. Additionally the INS can be used with LiDAR scanners, Sonars, and Optical Cameras.
