Antares 4G — Introduction

The Antares 4G is an embedded telematics device designed for fleet management and asset tracking applications with extensive capabilities, offering integrations with multiple sensors and accessories.

Includes SyrusCloud; a centralized management platform for device remote access, automatic firmware updates, network diagnostics, and remote application management. Includes software development tools for integration into any existing platform via APIs.

Special features include a global LTE Cat M1 modem, low power consumption mode, backup battery, optional factory built-in e-Sim, powerful GNSS capability, 3-axis accelerometer for measuring driving behavior and vehicle impact.

Its built-in cellular and GNSS antenna together with a water-resistant enclosure and backup battery makes it the ideal solution for fast, easy, and reliable installations.

Architecture

The Antares firmware is built around an event machine:

• Signals represent boolean conditions (ignition on, GNSS fix, speed exceeded, etc.)
• Events combine signals using logical expressions to trigger actions
• Commands configure signals, events, regions, destinations, and more
• Reports are sent via TAIP protocol over TCP/UDP to configured destinations

TAIP Protocol

All commands use the TAIP (Trimble ASCII Interface Protocol) framing:

>[Q|S]<COMMAND>[;FIELDS]<

• > — Start delimiter
• Q — Query (read current value)
• S — Set (write new value)
• <COMMAND> — 2–4 uppercase letters identifying the command
• ;FIELDS — Optional semicolon-separated parameters
• < — End delimiter

Responses follow:

>R<COMMAND_ECHO>[;FIELDS]<       ← success
>RER<CODE>:<COMMAND_ECHO><       ← error
