INTRODUCTION

A taximeter test is usually carried out using the rolling-road system that simulates a real route. Despite being quick and easy to calibrate, this has some limitations, which are resolved with a verification system based on GPS developed by Applus+.

THE Applus+ SOLUTION

GPSi is a taximeter verification system using measurement equipment based on satellite navigation (GNSS). The equipment consists of a portable device such as a tablet, on which the software for verification is executed, with the data received via an external high-frequency GPS antenna. 

In 2012, the Spanish Metrology Centre verified the calibration of the Applus+ GPSi system.
