developed the EGNOS technology to provide accuracy to 1.5 meters. Trailer tracking Trailer tracking refers to the tracking of movements and position of an articulated vehicle's trailer unit through the use of a location unit fitted to the trailer and a method of returning the position data via mobile communication network, IOT (Internet of things), or geostationary satellite communications for use through either PC- or web-based software. Cold-store freight trailers that deliver fresh or frozen foods are increasingly incorporating telematics to gather time-series data on the temperature inside the cargo container, both to trigger alarms and record an audit trail for business purposes. An increasingly sophisticated array of sensors, many incorporating RFID technology, is being used to ensure the cold chain. Container tracking Freight containers can be tracked by GPS using a similar approach to that used for trailer tracking (i.e. a battery-powered GPS device communicating its position via mobile phone or satellite communications). Benefits of this approach include increased security and the possibility to reschedule the container transport movements based on accurate information about its location. According to Berg Insight, the installed base of tracking units in the intermodal shipping container segment reached 190,000 at the end of 2013. Growing at a compound annual growth rate of 38.2 percent, the installed base reached 960,000 units at the end of 2018. Fleet management Fleet management is the management of a company's fleet and includes the management of ships and/or motor vehicles such as cars, vans, and trucks. Fleet (vehicle) management can include a range of functions, such as vehicle financing, vehicle maintenance, vehicle telematics (tracking and diagnostics), driver management, fuel management, health and safety management, and dynamic vehicle scheduling. Fleet management is a function which allows companies that rely on transport in their business to remove or minimize the risks associated with vehicle investment, improving efficiency and productivity while reducing overall transport costs and ensuring compliance with government legislation and Duty of Care obligations. These functions can either be dealt with by an in-house fleet management department or an outsourced fleet management provider. Telematics standards The Association of Equipment Management Professionals (AEMP) developed the industry's first telematics standard. In 2008, AEMP brought together the major construction equipment manufacturers and telematics providers in the heavy equipment industry to discuss the development of the industry's first telematics standard. Following agreement from Caterpillar, Volvo CE, Komatsu, and John Deere Construction & Forestry to
