UNCI is an acronym for U<\/strong>nderground N<\/strong>avigation and C<\/strong>ommunication I<\/strong>nfrastructure. The UNCI system is a combination of hard- and software. The hardware comprises the radio mesh nodes and the UNCI Navigator. Located within the navigator are amongst others the batteries, a radio transceiver and the INS sensor. <\/p>\n\n\n\n

Communication<\/strong> is done with a mesh network of miniature radio repeaters (the UNCI mesh nodes), no bigger then a few centimeters. Datapackets travel over short distances, (typically 10 to 20 meters) from repeater to repeater. With this system we send real-time voice, navigation and other digital data. <\/p>\n<\/div>\n<\/div>\n\n\n\n

Navigation<\/strong> is done by means of \u201cdead reckoning\u201d, also known as \u201cinertial navigation\u201d. The inertial navigation is supported by using the UNCI mesh nodes as a location reference point (patent granted). The UNCI Navigator recognizes the mesh nodes by their unique number and communicates with other UNCI Navigators via the mesh network. You can connect a smartphone or tablet to the UNCI Navigator for operation, presentation (GUI) and sound reproduction.<\/p>\n\n\n\n

This method is know in the literature as Landmark Based SLAM (Simultaneous Localization And Mapping).<\/p>\n<\/div>\n<\/div>\n\n\n\n
