The ST4955LCBW is a rugged, solar-powered GPS tracker designed for long-term outdoor asset monitoring and is fully Plaspy compatible for fast integration into your tracking and fleet management workflows. Built around low-power LTE Cat M1 and NB‑IoT cellular modules with 2G fallback, the ST4955LCBW delivers reliable connectivity across broad geographies while minimizing maintenance thanks to optimized energy harvesting and multiple internal battery options.
Whether you need remote asset tracking, trailer and container monitoring, or environmental telemetry for cold‑chain equipment, the ST4955LCBW pairs with Plaspy to enable real-time tracking, motion-based anti-theft alerts, and flexible telemetry. BLE support and a 1‑wire temperature interface expand sensor options, making this GPS tracker a straightforward choice for scalable, low-maintenance deployments.
Key Highlights
- Plaspy compatible: sends location and telemetry to Plaspy via standard TCP/UDP for fast integration into fleet management dashboards and alerts.
- Long-life solar charging: integrated solar panel and energy-harvesting design (≈40 mAh per hour) for extended outdoor operation and reduced maintenance.
- Multi-mode cellular connectivity: LTE Cat M1 and NB‑IoT with 2G fallback for broad global coverage and efficient data use.
- Advanced GNSS suite: GPS + GLONASS concurrent with support for QZSS, BeiDou, Galileo and SBAS; fast TTFF and ~±2.5 m CEP accuracy under normal conditions.
- Low-power operation: configurable power modes, ultra-low deep-sleep currents (<10 µA in minimal mode) and sample power figures for realistic deployment planning.
- Expanded telemetry: BLE for local sensors/configuration and a 1‑wire interface for external temperature sensing (ideal for environmental and cold-chain monitoring).
- Rugged, outdoor-ready: IP67 enclosure, compact form factor and multiple battery capacities to match mission profiles.
How It Works with Plaspy
Integrating the ST4955LCBW with Plaspy is straightforward: the device transmits GNSS fixes, motion and sensor telemetry over IP (TCP/UDP) to Plaspy endpoints. Plaspy ingests those packets to provide real-time tracking, historical playback, alerts and reporting for fleet management or asset monitoring. BLE and the 1‑wire temperature input allow on-site configuration and environmental telemetry to be forwarded into Plaspy as part of a unified data feed.
- Real-time location and telemetry updates to Plaspy using LTE Cat M1 / NB‑IoT (2G fallback) and TCP/UDP transport.
- External temperature readings via the 1‑wire interface forwarded as telemetry for cold‑chain or environmental alerts.
- Bluetooth Low Energy (BLE) for local sensor integration and device configuration; BLE-sourced data can be relayed to Plaspy.
- Motion and tamper detection from the built-in 3‑axis accelerometer for anti-theft alerts and activity-based reporting.
- Battery and solar-charge status available as telemetry so Plaspy can trigger maintenance, low-power warnings, or charging analytics.
- Supports higher-level workflows in Plaspy — e.g., fleet management dashboards, anti-theft notifications, and telemetry-driven maintenance. Where vehicle interfaces or external modules are added, Plaspy can also orchestrate fuel monitoring or immobilizer workflows through integrations.

Use Cases
- Remote asset tracking — long-term outdoor deployments such as pumps, cabins, or field equipment where solar charging minimizes visits.
- Trailer and container monitoring — intermittent reporting with GNSS fixes and motion-based anti-theft alerts to Plaspy for recovery workflows.
- Fleet asset recovery and management — add the ST4955LCBW to non-powered assets to extend Plaspy visibility without frequent battery swaps.
- Cold‑chain/environmental telemetry — connect a 1‑wire temperature sensor to monitor shipments or outdoor storage conditions and forward readings to Plaspy.
- Sensor-enabled asset tracking — BLE peripherals and accelerometer data enable richer telemetry (vibration, movement), useful for condition monitoring and theft detection.
Why Choose This Tracker with Plaspy
