Locator BG

Locator BG (locator.bg) is Finite Software Systems' own online GPS fleet-tracking platform. The core web application, repository `locator-bg-v1` / Composer package `fss/locator` ("Online GPS Tracking System"), is a classic MVC application built on FSS's in-house `fss/framework` v4 in PHP, served by Apache with mod_php and backed by an IBM DB2 database (accessed through PDO_ODBC) plus a Redis cache layer for sessions, caching and queues. It provides admin and member portals covering live tracking, fleet management, trips and mileage, service intervals, event and lost-connection notifications, reporting/KPI dashboards, organisations and users, SIM management, and subscription billing.

The platform ingests vehicle telemetry through a dedicated machine-to-machine backend. The Java `locator-interfaces` component ("Tracker Update Incoming Interface") receives GPS tracker updates and publishes them onto Apache Kafka, while the Java `locator-processor` consumes positions, writes to DB2/Redis and performs path interpolation between GPS points. This separates high-volume device ingest from the PHP front end, which the production infrastructure notes describe as a reverse-proxy/cron hub coordinating the live tracking pipeline.

Beyond raw tracking, the system delivers an extensive electronic toll layer for Bulgarian and EU road charging: integrations with Digitoll (e4a/c5), CargoTrack and HU-GO, a hosted Toll API (position reporting, balances, toll-data history, invoicing) exposed to logistics partners such as Sixfold, Project44 and VEROO, plus a Telenor/Yettel partnership surface. The work for the latter is corroborated by a Telenor Bulgaria reference letter describing FSS integrating its GPS-tracking system into the operator's business portal and marketing it as "Telenor Avtopark Resheniya" (fleet-management solution), with training and long-term support delivered after launch.
