MTi-G-700_hand-W

The MTi-G-700 by Xsens is a GPS-aided, IMU-enhanced GPS/INS that offers high-quality orientation and position. It makes use of sensory measurements from magnetometer, barometer, and a high-sensitivity GPS-L1 receiver to provide navigation estimates of position, velocity, and orientation at high data rates under high-dynamic conditions. The Xsens estimation engine (XEE) sensor-fusion framework enables the motion tracker to take advantage of... read more

Extreme Miniaturization: Seven Devices, One Chip to Navigate without GPS

April 11, 2013By
darpa-imu-O

The U.S. Military relies on GPS to aid air, land and sea navigation. Like the GPS units in many automobiles today, a simple receiver and some processing power is all that is needed for accurate navigation. But, what if the GPS satellites suddenly became unavailable due to malfunction, enemy action or simple interference, such as driving into a tunnel? Unavailability... read more

Innovation: Filling in the Gaps

Improving Navigation Continuity Using Parallel Cascade Identification
To reliably navigate with fewer than four satellites, GPS pseudoranges needs to be augmented with measurements from other sensors, such as a reduced inertial sensor system or RISS. What is the best way to combine the RISS measurements with the GPS measurements? The classic approach is to integrate the measurements in a conventional tightly coupled Kalman filter. But in this month’s column, we look at how a mathematical procedure called parallel case identification can improve the Kalman filter’s job, when navigating with three, two, one, or even no GPS satellites. read more
