The ST-915 GPS Tracker is a rugged, waterproof Plaspy compatible GPS/GSM/GPRS locator engineered for long autonomous operation and reliable outdoor tracking. Built around a UBLOX UBX-G7020 GNSS module and quad-band 2G modem, the ST-915 delivers accurate position fixes, extended standby from a large Li‑ion battery, and straightforward integration with tracking platforms — including Plaspy — by pointing the unit to a server IP/port via SMS.
Designed for cars, motorcycles, trailers and high-value assets that require long battery life and durable construction, the ST-915 offers real-time tracking, history playback and basic telemetry reporting over GSM/GPRS. The device ships without a SIM card so you can choose the local operator and data plan that best fits fleet management, anti-theft and remote monitoring needs.
Key Highlights
- Plaspy compatible: configure server IP/port via SMS to forward location and telemetry to Plaspy for real-time tracking and reports.
- Long standby: large 10000 mAh 3.7 V Li‑ion battery offers up to 60 days standby in low-power modes for extended off-grid operation.
- Rugged, waterproof design: built for harsh outdoor environments where asset or vehicle exposure is likely.
- Accurate GNSS performance: UBLOX UBX-G7020 module with ~5 m typical accuracy and high sensitivity (-159 dBm).
- Global 2G connectivity: quad-band GSM/GPRS (850/900/1800/1900 MHz) for broad carrier compatibility where 2G service is available.
- Easy activation and management: SMS-based APN and server configuration plus free SinoTrack platform and app included as an option.
- Compact and lightweight: small footprint (10 cm × 8 cm × 2.5 cm) and approximately 45 g for discreet mounting on vehicles and assets.
How It Works with Plaspy
The ST-915 sends GNSS positions and telemetry over GSM/GPRS to a configured server IP and port. By using the device's SMS commands to set the APN and the target server, integrators and end users can point the unit to Plaspy endpoints so Plaspy receives live location updates, history points and status messages. Configuration is simple: insert a compatible SIM, set APN and server details by SMS, and the tracker will begin reporting to Plaspy in real time.
- Real-time location and telemetry updates delivered over GPRS to the configured Plaspy server.
- History playback and position logs accessible in Plaspy for route review and audit trails.
- Simple SMS-based configuration (APN, server IP/port) for fast deployment without special tools.
- Works with Plaspy's fleet management features once pointed to Plaspy server endpoints (data forwarding via standard SinoTrack-style reporting).
- Free vendor platform (SinoTrack) included as a backup option; you can choose Plaspy as the primary platform via IMEI/server configuration.

- Asset tracking for trailers, containers and valuable outdoor equipment requiring waterproof and rugged hardware.
- Motorcycle and car tracking for theft recovery and location monitoring with long standby between charges.
- Remote site monitoring where power is limited and devices must operate autonomously for weeks.
- History playback and route auditing for compliance or operational analysis in mixed vehicle fleets.
Why Choose This Tracker with Plaspy
When paired with Plaspy, the ST-915 becomes a dependable building block for real-time tracking, telemetry and practical fleet management. Its combination of a proven UBLOX GNSS engine, rugged waterproof housing and very large battery makes it ideal where long unattended operation matters. Because the unit accepts a user-provided SIM, you retain control over carrier choice and data plans, which helps optimize recurring costs. Integrators will appreciate the simple SMS-based APN and server setup that enables rapid deployment to Plaspy without special provisioning tools.
Practical advantages include vendor documentation and start-up support, a free lifetime access option to the vendor's SinoTrack platform, and a 2-year product warranty with customer support for setup. Note that the ST-915 focuses on core GPS/GSM/GPRS location and telemetry reporting; features such as dedicated ignition inputs, fuel monitoring, immobilizer control or Bluetooth sensors are not specified in the basic product sheet and should be confirmed with the vendor if required for your Plaspy deployment.
