The P901 is an ultra-thin, ID card–style GPS tracker designed to be Green-Gps compatible for secure, real-time tracking and team communications. Combining LTE/GPRS connectivity with GPS + Beidou positioning and LBS fallback, the P901 delivers accurate location data, SOS alerts and group push-to-talk voice communication in a slim wearable form factor ideal for security personnel, event staff and lone-worker protection.
The device pairs tightly with cloud platforms and mobile clients like Green-Gps to provide location, telemetry and voice capabilities in one compact unit. Built-in VoLTE two-way calling, group PTT, one-key SOS and remote FOTA updates make the P901 a practical choice where continuous situational awareness, reliable communications and remote device management are required.
Key Highlights
- Green-Gps compatible for real-time tracking and cloud integration with location and telemetry updates.
- ID-card form factor (100 × 60 × 12.5 mm) — wearable or clipped for patrols and staff.
- Integrated VoLTE two-way calling plus group push-to-talk (PTT) for instant team voice communications.
- GPS + Beidou positioning with LBS fallback and <5 m typical accuracy for reliable location data.
- One-key SOS alarm and configurable alarm modes (GPRS/SMS/CALL) for rapid incident response.
- Long-lasting 2200 mAh rechargeable battery with configurable upload/sleep intervals to extend endurance.
- Remote firmware updates (FOTA) and SMS-based remote configuration for scalable device management.
How It Works with Green-Gps
The P901 streams location and event data to Green-Gps over LTE/GPRS. Green-Gps receives GNSS-derived coordinates (GPS + Beidou) and cellular-based LBS as fallback, then displays the unit on maps in real-time, logs historical routes for playback, and triggers alerts based on SOS or other configured events. Voice interactions and PTT are managed on-device while Green-Gps uses the device’s position and status to correlate communications with tracked assets.
- Real-time location and telemetry updates (GNSS + LBS) visible in Green-Gps dashboards and mobile apps.
- One-key SOS alarm pushed to Green-Gps with configurable alert channels (GPRS/SMS/CALL).
- VoLTE two-way calling and group PTT: on-device voice with position context available through Green-Gps logs.
- Historical route playback from internal memory (up to 2000 records) via Green-Gps’s route reports.
- Remote device configuration, low-battery alerts, and FOTA initiation through Green-Gps-compatible workflows or SMS commands.

Why Choose This Tracker with Green-Gps
The P901 delivers a focused mix of real-time tracking and team voice communications that aligns with Green-Gps’s platform strengths. Its compact ID-card design, broad LTE band support and GNSS accuracy support international deployments where Green-Gps customers need location, SOS alarms and immediate voice contact in one device. Remote FOTA, SMS configuration and internal logging make large-scale rollouts and ongoing maintenance straightforward, while configurable upload intervals and power-saving modes help maximize battery life in field use.
For organizations implementing fleet management, telemetry and anti-theft workflows via Green-Gps, the P901 provides a practical building block for tracking people and assets that require both situational awareness and instant two-way voice. If you require additional I/O for fuel monitoring, ignition or immobilizer control, or Bluetooth sensors, confirm integration paths with your Green-Gps deployment team or consider complementary peripherals — the P901 is optimized where on-device voice plus precise GNSS location form the core requirement.
