1Product Description

1.1 Overview

This document is the official user manual for the SEAL Wearable GPS Tracker designed and developed

by Tektelic Communications, henceforth referred to as SEAL/SEAL-Ex.

The SEAL/SEAL-Ex is a light, small factor, long battery lifetime, low-cost LoRaWAN sensor used for

tracking people (as a wearable device) or equipment, based on GNSS and BLE technologies. The

SEAL/SEAL-Ex comes both as an ATEX/IECEx certified version (henceforth referred to as SEAL-Ex),

certified to operate in potentially hazardous and explosive atmospheres, and as a regular non-

ATEX/IECEx version (henceforth referred to as SEAL).

The SEAL/SEAL-Ex uses Semtech SX1261 modem for LoRaWAN communication, and a low-power, IoT

targeted MCU, STM32 from STMicroelectronics with built-in BLE module, 256 kB of RAM, and 512 kB of

flash. Other hardware features include a high-sensitivity GNSS receiver from u-blox (MAX-M10S), a low

power 3-axis MEMS accelerometer from STMicroelectronics (LIS3DH), and a digital barometric air

pressure sensor from Infineon (DPS310). There is also a push button used as an emergency/SOS/panic

button, 1 buzzer (GT-0601A from Soberton Inc.) to locally indicate the emergency button (EB) press or

safety hook (SH) disconnection, 1 mute button (MB) to manually mute (disable) or unmute (enable) the

buzzer, and 2 sets of LEDs, 1 at the top 1 and one at the front, to indicate emergency status, low battery,

and the system going into or out of DEEP SLEEP, are among other features.

Table 1-1: SEAL Wearable GPS Tracker Model

Each of the ATEX/IECEx certified and the non- ATEX/IECEx versions have two functional variants: with

and without a safety clip harness. The safety clip harness detects whether a safety hook is placed on

the unit or not, triggering a local alarm if the user is to be warned.
