What Pósitron does

Pósitron, operating as PST Eletrônica LTDA, is a Brazilian manufacturer of automotive electronics and a subsidiary of the US-based Stoneridge Group. Founded in 1988 and headquartered in Manaus, Amazonas, the company designs, manufactures, and distributes vehicle security systems (car and motorcycle alarms), vehicle tracking and telematics services, automotive infotainment (multimedia centers and MP3 players), digital tachographs, ADAS camera systems, electronic accessories (window modules, central locking), and — as of April 2025 — AGM batteries for motorcycles and passenger vehicles. Its technology stack combines GPS/GSM/GPRS/4G connectivity with proprietary hardware and in-house developed software, unified through the Pósitron Guardião mobile app and the Stoneridge Digital Services web platform for fleet management and tachograph data.

The company serves three primary customer segments: individual vehicle owners (consumer subscriptions for tracking, alarm, and insurance-integrated products), commercial fleet operators (digital tachographs, MDVR video monitoring, telematics, and ADAS), and a B2B2C network of certified installers and resellers. Its business model blends one-time hardware sales (alarms, accessories, audio, batteries) with recurring revenue from monthly/annual tracking subscriptions, tachograph cloud data plans (freemium Basic and paid Premium), and insurance-bundled tracking products offered in partnership with Yelum and Usebens. Distribution is multi-channel, combining a proprietary e-commerce platform, televendas (0800 lines and WhatsApp), a nationwide partner store and distributor network, certified installers, and OEM supply relationships — including a telematics module supplied to Volkswagen since August 2024.

Pósitron is described as the only Brazilian tracking company with fully in-house hardware development, software development, and service provision. Its Manaus facility uses Industry 4.0 production processes and is certified for 100% renewable energy use under the I-REC standard. The company employs between 1,001 and 5,000 people and operates primarily in Brazil with positioning across Latin America through the Stoneridge Group's footprint in more than 15 countries.
