SubPos is an open source, indoor positioning system that can be used in various environments such as metro lines, shopping malls, car parks, art galleries or conference centers, essentially anywhere GPS doesn't penetrate. SubPos is a complete positioning system that doesn't require expensive licencing, specialised hardware or laborious area profiling and isn't reliant on data connectivity (a connection to a database or cellphone coverage is not required).
SubPos defines an accurate method for subterraneous positioning in different environments by exploiting all the capabilities of Wi-Fi. Plug and play SubPos Nodes or existing Wi-Fi access points are used to transmit encoded information in a standard Wi-Fi beacon frame, which is then used for passive position trilateration by a device of your choice (as long as it contains a Wi-Fi receiver). No more sending your position to external location providers when navigating indoors.
With development progressing, accuracy of up to +-0.5 meters is currently achievable in standard indoor environments. Further developments are being made to increase this accuracy using various techniques such as accurate Node transmit timing and averaging functions.
A systems engineer by day and an electronics tinkerer by night. Each day is a constant struggle between balancing sleep, caffeine, work and play. By play I mean, inhaling what is probably too many solder fumes.
