 Oyster LoRaWAN Long-Life Battery GPS Tracker

COMPACT LOW-COST BATTERY-POWERED LoRaWAN GPS TRACKER

The Oyster is a compact, rugged GPS tracking device that has been designed for tracking containers, trailers, skip bins, and other assets where super-long battery life is required without sacrificing the frequency of updates and performance.

The IP-67 rated housing is rugged and UV stable, so the Oyster can be mounted on assets that are exposed to rain, dust and marine conditions.

By utilising the latest technology, the Oyster can operate in ultra-low power modes, and with an incredible battery life of up to 5 years the Oyster can be attached to assets and tracked without needing to change batteries. The Oyster has built-in antennas for GPS reception and for LoRaWan communication, a 3D accelerometer, and a high-performance GPS that can track both GPS and GLONASS satellites simultaneously.

The Oyster LoRaWan uses LoRaWan technology to give you coverage of your assets at a low data cost. The Oyster LoRaWan is available in 868MHz and 915MHz versions to cater for the various LoRawan regions around the world.

The option of using extended temperature range AA batteries allows the Oyster to be used in extreme climates and temperatures:

  • IP67 Rugged weather-proof housing
  • Fully powered by 3 AA consumer batteries
  • Up to 5 years tracking on LoRaWAN low cost network (once daily)
  • Small, Compact and easy to install and conceal
  • Configure by USB cable

Locate assets for extended periods

Track up to 5 years (once daily) using standard size AA cell batteries or up to two years with regular updates.

Non-powered assets 

Ideal for equipment, containers, skips, trailers, pumps, generators and other non-powered assets that are exposed to the elements.

Lowest cost connectivity

LoRaWAN connectivity offers lowest cost connections on an expanding global network.

 

Hardware Features

Low-profile IP67 rugged housing

The IP67 rated housing is made of sturdy ABS/Polycarbonate plastic to survive bumps and knocks and to survive many years in the sun and weather.

It is low-profile making it easier to mount in the corrugation on containers or concealed on the underside of a trailer, for example.

The housing screws together for easy assembly, and has 2 convenient mounting tabs. It also has ‘strap slots’ allowing the Oyster to be cable tied or metal strapped to an asset.

Dimensions: 100 mm x 65 mm x 19 mm
Weight: 160 grams with batteries

Batteries

AA size

The Oyster uses standard “AA” size batteries which provide a balance between size and capacity

Alkaline

Low cost off-the-shelf alkaline batteries can be used in the Oyster

Off-the-shelf Lithium

For applications that require extreme temperature or extra long-life we recommend that off-the-shelf 1.5V lithium batteries are used. These are readily available from retail outlets, for example Duracell and Energizer

Sleep Current

10uA (micro amps)

 

 

Battery Life with Adaptive-Tracking

The Oyster can be set to use Adaptive-Tracking technology where the accelerometer and GPS data are used to intelligently work out if it is moving and to send frequent updates, and to scale the update rate down to once per day if the asset is stationary - to preserve battery life.

5 years @ one position per day

 

Operating Temperature

-20°C to +60°C 1

For operation in extreme temperatures, the Oyster must be fitted with lithium batteries.

High sensitivity GPS

UBLOX MAX-M8Q GPS module

Supports concurrent GPS and GLONASS
72 channel high sensitivity receiver
-167dBm industry leading tracking performance
Optimal hot-start performance
AssistNow Autonomous Offline aiding data for fast time-to-first-fix and performance in urban canyon environments

GLONASS

The Oyster uses both the GPS and GLONASS positioning systems simultaneously.

This allows the device to use twice the number of satellites to get a position fix – making it faster and more accurate.

Low noise GPS amplifier

GPS signals are boosted by a special low-noise amplifier (LNA)
This allows the Oyster to operate where normal units will fail to receive GPS signal – like in a container stack!

LoRaWan Communications

The Oyster uses a high power radio transmitter / receiver that operates on LoRaWan networks, and is available in variants for the various LoRaWan frequencies around the world.

Certifications

In progress

Internal Antennas

Internal GPS and RF antennas tuned by the RF laboratories to ensure optimal performance

3 axis accelerometer

The 3-axis accelerometer allows the Oyster to ‘sleep’ in an ultra-low power state yet still wakeup when movement occurs.

Future firmware versions will allow for harsh G-force detection (like objects being dropped)

Configuration Cable

The Oyster LoRaWan caters for a USB configuration adapter and cable, which is used to program firmware updates and configuration information on the device. The most common configuration parameters are also able to be updated OTA via LoRaWan downlink messages.

The Oyster has a USB configuration cable that is required to update the device firmware. It is purchased seperately.

 

Firmware Smarts

LoRaWan Data Management

The Oyster LoRaWan device manages the data plan that is configured for to maximize the use of the allocated LoRaWan data messages

OTA Configuration

The Oyster can be remotely configured and some of the key operational parameters updated via the LoRaWan downlink messages (your data plan needs to support downlink messages).

AssistNow Autonomous Offline

The Oyster will track successfully where other devices just give up.

This fantastic technology allows the GPS to predict which satellites are in orbit above it and to dramatically reduce the time-to-first-fix of the GPS, and the overall performance of the GPS, especially in ‘urban canyon’ or forested environments.

Software & Data Management

Data from the Oyster LoRaWan device is sent to LoRaWan gateways, which in turn will report the data via their LoRaWan cloud infrastructure to the back-end server platform for processing and reporting. The LoRawan network server is not provided by Digital Matter.

There are several LoRaWan network service providers for customers to choose from. Each of them have their own management interface and formats for providing data to a software platform.

Please contact Digital Matter if you require information on the integration of the Oyster LoRaWan data payloads.

User Interface:

This can be Digital Matter’s Telematics.Guru platform which has built-in support for the Oyster LoRaWAN device and protocols, or to your own server platform. Please contact Digital Matter if you required information on the integration of the Oyster LoRaWAN data formats.

 

 

IP67 Weather-Resistant, Rugged Housing

The IP67 rated housing is made of sturdy ABS/Polycarbonate plastic to survive bumps and knocks and to survive many years in the sun, rain and weather.

Compact & Low-Profile

Compact and low-profile means easy mounting in the corrugation on containers or concealed on the underside of a trailer, or anywhere you choose to hide the Oyster.

The housing screws together for easy assembly, and has 2 convenient mounting tabs. It also has ‘strap slots’ allowing the Oyster to be cable tied or metal strapped to an asset.
