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.
7 years @ one position per day

|
Operating Temperature
|
-20°C to +65°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!
|
|
Sigfox Communications
|
The Oyster uses a high power radio transmitter / receiver that operates on the Sigfox network, and is available in variants for the various Sigfox Zones around the world.
RCZ1 Europe and Middle East
RCZ2 North America and Brazil
RCZ4 Australia, New Zealand, South America, Hong Kong, South East Asia

|
|
Internal Antennas
|
Internal GPS and Sigfox 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)
|
|
Flash memory
|
The flash memory is used to data, parameters and other important information that needs to be securely stored.
A future firmware version will allow for geo-fences to be loaded into the flash memory of the device and used for geo-fence alerting on the device.
|
|
Configuration Cable
|
The Oyster Sigfox caters for a USB configuration adapter and cable, which is used to program firmware updates and configuration information on the device.
