The ST4315 series is a compact, vehicle-mounted GPS tracker built for Plaspy-compatible fleet and asset management. Designed to work with modern telematics platforms, the ST4315 provides reliable real-time tracking, robust telemetry and rugged hardware that withstands harsh field conditions—making it an excellent choice for operators who need accurate position data, crash reconstruction and driving pattern analysis on Plaspy.
Available in multiple variants to suit different installation and integration needs, the ST4315 supports LTE Cat M1, NB‑IoT and legacy 2G (EGPRS) connectivity, buffered logging for up to 10,000 records and model-dependent interfaces such as RS232 and 1‑Wire. These capabilities combine with low-power modes and IP67 protection to enable long-lived, low-maintenance deployments for fleet management, anti-theft and general asset tracking on the Plaspy platform.
Key Highlights
- Plaspy compatible: delivers continuous GPS tracker data and telemetry for real-time tracking and fleet management workflows.
- Multi-network cellular connectivity: LTE Cat M1 and NB‑IoT with EGPRS fallback for broad coverage and carrier resilience.
- High-accuracy GNSS: GPS + GLONASS with SBAS support and ~±3 m CEP positioning accuracy for dependable location services.
- Rugged, low-power design: IP67 enclosure, wide input voltage (DC 8–33 V) and deep-sleep currents under 2 mA to extend battery-backed operation.
- Local buffering and analytics-ready data: on-board memory for up to 10,000 records preserves data during outages and enables crash reconstruction and driving pattern analysis (optional).
- Flexible I/O and peripheral support: up to six wired inputs/outputs (model dependent) plus optional RS232 and 1‑Wire ports for sensors and ignition status.
- Variant options: multiple pinouts and I/O/port combinations (ST4315, ST4315U, ST4315W, ST4315R, ST4315RW) to match installation and telemetry needs.
How It Works with Plaspy
When integrated with Plaspy, the ST4315 streams location and telemetry via TCP/UDP over LTE Cat M1, NB‑IoT or EGPRS to provide near real-time tracking, alerts and historical reporting. Plaspy ingests the device’s GNSS positions, event inputs and buffered records so fleets maintain continuity of data even if cellular coverage is interrupted.
- Real-time location and telemetry updates delivered to Plaspy for live tracking and map visualizations.
- Geofencing (circular and polygonal) and event generation for entry/exit alerts and route enforcement.
- Digital I/O and ignition status (model dependent) for engine-on/off events and alarm inputs.
- Buffered logging of up to 10,000 records for upload to Plaspy after reconnection, enabling crash reconstruction and DPA (where activated).
- Integration-ready ports (RS232, 1‑Wire) and optional BLE enable connection to external sensors—allowing telemetry expansion such as temperature or third-party fuel sensors when deployed with appropriate peripherals.
