Inertial Sense Releases Small RTK-INS For Mass-Market Consumer Applications

Inertial Sense, creators of the smallest high-performance precision GPS-Inertial Navigation Systems, recently announced the release of precise RTK-level accuracy. The new inertial navigation solution offers an accuracy of 2-3 centimeters GPS position, in combination with inertial sensors (including on-board sensor fusion), at a lower price point than competitive INS+RTK Sensor offerings, according to the manufacturer.

Inertial Sense designs and manufactures precision INS+RTK GPS sensors said to deliver fast, accurate, and reliable altitude, velocity, and position for a wide range of autonomous vehicle applications. Their new micro INS with RTK is designed to provide a high degree of precision for orientation and GPS in a small package. Standard INS/GPS sensors offer accuracy in the range of 1.5-2 meters, while Inertial Sense’s micro INS with RTK offers accuracy of 2-3 centimeters.

“The incredibly small size of our new micro INS with RTK sensor, in combination with its extremely affordable price point, will make this type of highly sophisticated technology accessible for general consumer applications for the very first time,” said Walt Johnson, Founder and CTO, Inertial Sense. “We are offering RTK at a size, accuracy and price point that the market has never seen before.”

By optimizing the manufacturing processes for high volume applications, the micro INS with RTK sensor is literally as small and lightweight as a dime and said to be economical. This sensor will enable the navigation of all types of autonomous vehicles with a very high degree of precision. In the image below you can see a vehicle traveling under an overpass. The 3 centimeter accurate RTK-Inertial Navigation track holds true to the vehicle’s position while the standard GPS signal is lost.


Inertial Sense patented modules are currently being sold worldwide at volume for a broad variety of applications including:

  • Autonomous Navigation: Drones, Ground Robotics, Precision Ag, Automobiles
  • Aerial Surveys: UAV Payloads for 3D Mapping, Photogrammetry, Orthomosaics
  • Gimbal Stabilization and Antenna Pointing
  • 3D motion capture and Personnel Tracking
