Astra Telematics - AT501

The AT501 Mini Asset Tracker is a compact, battery-powered GPS tracker engineered for long-term monitoring of small, unpowered assets. Plaspy compatible out of the box, the AT501 combines multi-network cellular connectivity (e-SIM with LTE‑M, NB‑IoT and 2G fallback), multi-constellation GNSS, and ultra-low-power operation to deliver a reliable asset tracking solution for fleets of tools, trailers, containers and other remote equipment.

Designed for simple installation and durable field use, the AT501 offers IP68 weather protection, a magnetic mount with optional M4 bolt attachment, and a replaceable LTC battery pack for up to eight years of operating life in low-power reporting modes. Its BLE support and accelerometer allow local configuration and event-based telemetry that integrates smoothly with Plaspy for fleet management, anti-theft alerts and long-term telemetry reporting.

Key Highlights

• Extended battery life — 13,000 mAh replaceable LTC battery pack (5 x ER14505) with up to 8 years in low-power mode at 24-hour reporting intervals.
• Plaspy compatible — integrates position and telemetry into Plaspy for fleet management, reporting and alerting.
• Rugged, field-ready design — IP68 enclosure, internal GSM/GNSS antennas, magnetic mount plus M4 bolt option for secure installations.
• Future-proof connectivity — e‑SIM with LTE‑M and NB‑IoT plus GSM/GPRS (2G) fallback for broad cellular coverage.
• Multi-constellation GNSS — GPS, Galileo, GLONASS & BeiDou with internal 15 mm GNSS antenna for reliable positioning.
• Event-based reporting — built-in MEMS accelerometer triggers movement reports to maximize battery life and improve location accuracy between motion vs stationary states.
• Bluetooth Low Energy — local configuration, diagnostics and setup with a smartphone using BLE.
• Replacement battery & customization — spare BT501 pack available; hardware and reporting customization offered at no extra cost for Plaspy integration.

How It Works with Plaspy

The AT501 delivers position and telemetry to Plaspy using cellular uplinks managed by its e‑SIM and multi-network modem. For assets that require infrequent reporting, the device leverages scheduled low-power transmissions and accelerometer-triggered event reports; for assets that need more frequent updates Plaspy can be configured to accept shorter reporting intervals while balancing battery consumption. BLE provides a convenient local channel for provisioning and diagnostics before the device is registered in Plaspy.

• Real-time location and telemetry updates when reporting intervals are configured for frequent updates; otherwise scheduled/event-based reports preserve battery life.
• Movement detection and event-based alerts using the internal MEMS accelerometer to reduce unnecessary uplinks and improve location relevance.
• Multi-network uplink (LTE‑M, NB‑IoT, 2G fallback) ensures telemetry reaches Plaspy across varied coverage areas.
• Bluetooth Low Energy (BLE) for on-site configuration, diagnostics and commissioning with Plaspy device profiles.
• Note: the AT501 does not include CANBus, RS232, ADC or dedicated digital I/O — ignition, immobilizer or direct fuel monitoring inputs are not supported by this model.

Technical Overview

Use Cases

• Fleet management for non-powered assets — track trailers, containers and attachments across long service intervals with minimal maintenance.
• Tool and equipment tracking — monitor high-value portable tools and small machinery stored outdoors or on-site with strong water/dust protection.
• Container and cargo monitoring — durable, long-life tracking for seasonal or infrequently moved assets where extended battery life is essential.
• Remote telemetry for stationary assets — movement-triggered reporting reduces uplink costs while preserving the ability to detect theft or relocation.
• Simple installations where a magnet or single bolt mounting is preferred — quick deployment across many assets in a fleet.

Why Choose This Tracker with Plaspy

As a Plaspy compatible GPS tracker, the AT501 is optimized for organizations that need reliable, long-duration asset visibility without frequent maintenance. Its replaceable 13,000 mAh battery pack and low-power reporting modes make it ideal for large fleets of unpowered assets where battery replacement cycles and field service need to be minimized. Robust ingress protection and internal antennas reduce point-of-failure risks, while multi-network cellular support helps keep telemetry flowing into Plaspy even in marginal coverage areas.

Plaspy integration makes it straightforward to consolidate real-time tracking, telemetry and event alerts into a single fleet management view. While the AT501 is not intended for vehicle engine telemetry (it does not provide CANBus, ADC or ignition inputs) it excels at anti-theft detection, movement-based alerts, and long-term location history for assets. Bluetooth sensors and on-site BLE configuration streamline commissioning, and vendor-provided customization ensures reporting formats and schedules align with your Plaspy workflows and operational needs.
