GPS has its limitations in urban areas where signals can get noisy. Now, engineers in the Netherlands have developed “SuperGPS” – a hybrid positioning system that combines wireless and optical connections to pinpoint locations within centimeters.

If you want to maximize the number of trains that can operate on one line simultaneously, it's crucial that you know the exact location of each train at all times. A new system is designed to help, by analyzing the magnetic properties of the rails.

If you hear gunshots in an urban setting, it's important to get the police to their source as quickly as possible. A new system is being developed to help, by combining autonomous drones with an existing shot-locating technology.

Sandia National Laboratories is developing an avocado-sized vacuum chamber made out of titanium and sapphire that could one day use quantum mechanical sensors to provide GPS-grade navigation without the need for satellites.

BAE Systems has developed the world's smallest, lightest, and most power-efficient military M-Code GPS receiver. About the size of a postage stamp, the MicroGRAMTM-M can be installed in handheld devices and is resistant to jamming and spoofing.

A new prototype Companion Collar smart collar is being developed by the CSIRO's digital specialist arm, Data61, and agtech company Ceres Tag that will allow pet owners to track their animal across both long and short distances.

​If you're lost or injured in the wilderness, there's a good chance that there won't be cellular coverage where you are – that means you can't just phone for help. Your smartphone may still get you found, however, thanks to a new app designed at Spain's Universidad de Alicante.
