Real time locating systems

efcmagnew · Jun 12, 2012

Hello folks. I am searching for a highly accurate RTLS that I can deploy in an indoor/outdoor area. I don't know if a system capable of what I need is even possible given today's technology, but if anyone can help me that'd be great. Here are the basic parameters:

Accuracy (3 dimensions) <12 inches, preferably better.

Maximum tag-to-antenna distance: >25 feet

Maximum per-tag refresh rate: <.3 seconds, preferably much less.

Scalability: 50 tags minimum. Preferrably infinite scalability.

Is there anything in today's RTLS toolkit that can reasonably satisfy these requirements?

Thanks in advance

This same topic comes up over and over and over... again in various Eng-Tips forums.

Short answer: There's no such technology, but IPS is on the horizon.

There are new methods that can achieve 1 cm accuracy, either using FFT processing of cooperative FMCW signals or multitone CW radar methods. Some papers at the IMS2012 on the FMCW method. 25 feet probably means a battery operated repeater, though.

The Americas Cup catamarans have GPS providing 2cm accuracy.
