Expert Opinions: Optimum number of GNSS signals for PNT device

February 22, 2016By

Q: What is the optimum number of GNSS signals to include/process in a consumer-grade PNT device? A: The cost for including additional silicon to a receiver for processing more signals is low, thanks to multiplexing hardware and high clock speeds. Having more satellite measurements allows the receiver to be selective about which ones it actually uses for PVT calculations, so... read more

We had to constantly adjust the angles to get the best reception, using aluminum foil to improve the signal. Wow, how things have changed. Today, consumer users of smartphones, Fitbits, smartwatches, tablets and a... read more

Research Online: Multi-sensor SLAM key to tactical situational awareness

February 22, 2016By

Rescue and military applications require rapid, accurate and reliable information about unknown environments. Simultaneous Localization and Mapping (SLAM) is a key technology for providing an accurate and reliable infrastructure-free solution for indoor situational awareness. The researchers’ approach is to integrate a monocular camera, multiple inertial measurement units (IMUs), a barometer and a ranging sensor to obtain a solution for SLAM,... read more

Out in Front: ION-ITM addresses ethics of autonomy
