Besides being cost-effective in comparison with underground solutions, the Maglev technology is a clean and low-noise mass transportation. In this paper, we propose a low-cost automatic braking system for Maglev trains. There is a myriad of sensors and positioning techniques used to improve the accuracy, precision and stability of train navigation systems, but most of them result in high implementation costs. In this paper, we develop an affordable solution, called Redundant Autonomous Safe Braking System (RASBS), for the MagLev-Cobra train, a magnetic levitation vehicle developed at the Federal University of Rio de Janeiro (UFRJ), Brazil. The proposed braking system employs GNSS (Global Navigation Satellite System) receivers at the stations and trains, which are connected via an ad-hoc wireless network. The proposed system uses a cooperative error correction algorithm to achieve sub-meter distance precision. We experimentally evaluate the performance of RASBS in the MagLev prototype located at the campus of UFRJ, Brazil. Results show that, using RASBS, the train is able to dynamically set the precise location to start the braking procedure.<\/jats:p>","DOI":"10.3390\/info11110531","type":"journal-article","created":{"date-parts":[[2020,11,16]],"date-time":"2020-11-16T11:04:20Z","timestamp":1605524660000},"page":"531","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["An Accurate GNSS-Based Redundant Safe Braking System for Urban Elevated Rail Maglev Trains"],"prefix":"10.3390","volume":"11","author":[{"given":"Jo\u00e3o Batista Pinto","family":"Neto","sequence":"first","affiliation":[{"name":"Grupo de Teleinform\u00e1tica e Automa\u00e7\u00e3o, Universidade Federal do Rio de Janeiro, Rio de Janeiro 21941-901, Brazil"},{"name":"Instituto Federal de Educa\u00e7\u00e3o, Ci\u00eancia e Tecnologia de Rond\u00f4nia (IFRO), Av.
