History of Inertial Navigation

We need lots of science to build INS/GNSS systems - initial list of scientist who contributed below.

INTO Seminar

The Finnish Geospatial Research Institute (FGI), the University of Helsinki (UH), and the Nordic Institute of Navigation (NNF) will organized a seminar on Indoor and Challenging Navigation, INTO 2019, on Friday 29th of November 2019. We presented theory behind wheel-mounted inertial navigation and our latest products at the event. Our presenation can be downloaded from here.

IEEE Inertial 2019

We visited the 6th IEEE International Symposium on Inertial Sensors & Systems, Naples, Florida in April. Excellent conference focusing on inertial sensor design and applications. This is a single track conference with high quality oral and poster presentations. Dr. Oleg Mezentsev from Pacific Inertial Systems presented our joint paper “Design and Performance of Wheel-Mounted MEMS IMU for Vehicular Navigation“. You can download the post-print from here.

What to do on long, intercontinental flights? Play Kaggle, for example.

Dead Reckoning

Dead reckoning is a process where position is computed by integrating speed and course over time. For groung vehicles, speed is typically optained from wheel-ticks and heading from gyroscopes. We can, of course use vision as well, as in the video below.

Earth Rotation

[Test post] Inertial frame is the reference for strapdown gyro measurements. Earth fixed coordinate frame rotates relative to this frame and this angular rate can be measured.

The video above looks toward North. In the video below, the camera points toward East.

And here we take a look towards South. Earth is rotating with respect to distant stars - but what would we measure with gyros if things were vice versa? Inertia is a good source for thought experiments!
