Low-profile IP67 rugged housing
The housing screws together for easy assembly, and has 2 convenient mounting tabs. It also has ‘strap slots’ allowing the Oyster2 to be cable tied or metal strapped to an asset. It is low-profile making it easier to mount in the corrugation on containers or concealed on the underside of a trailer, for example.Dimensions:L 137 x W 72 x H 30mm
The Oyster2 uses 3 x “AA” size batteries.
The device can be fitted with off-the-shelf 1.5V Lithium batteries. These are readily available from retail outlets, for example Energizer Ultimate Lithium.
Lithium Thionyl Chloride (LTC) Batteries:
For optimum performance the device can be fitted with LTC Batteries. This kind of battery offers extended temperature tolerance, high capacity and extremely low self-discharge rates.
Battery Life with Adaptive-Tracking
The Oyster2 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.
-20°C to +60°C
For operation in extreme temperatures, the Oyster2 must be fitted with LTC batteries. Batteries are affected by temperature extremes and typical performance is dependent on temperature.
High sensitivity GPS
- Supports concurrent GPS and GLONASS
- 72 channel high sensitivity receiver
- -167dBm industry leading tracking performance
- Optimal hot-start performance.
- AssistNow Offline aiding data for fast time-to-first-fix and performance in urban canyon environments
The Oyster2 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 (LNA)
GPS signals are boosted by a special low-noise amplifier (LNA). This allows the Oyster2 to operate where normal units will fail to receive GPS signal – like in a container stack!
The Oyster2 can be manufactured for specific markets around the world depending on their modem requirements. Available in 2G or 4G
uBlox SARA-R410M Modem operates on all major global LTE-Cat-M1 and NB-IoT bands. These new low-power networks are specifically designed for IoT applications, providing great battery life
Supported LTE bands:
1-5, 6, 8, 12, 13, 17, 19, 20, 25, 26, 28
Internal GPS and Cellular RF antennas tuned by the RF laboratories to ensure optimal performance.
3 Axis Accelerometer
The 3-axis accelerometer allows the Oyster2 to ‘sleep’ in an ultra-low power state yet still wakeup when movement occurs.
The accelerometer also allows for High G-force event detection (like assets being dropped or involved in accidents)
The Oyster2 has enough flash to store many weeks of data records, and will record information even when out of cellular coverage.
The flash memory is also used to store firmware updates, GPS aiding data, parameters and other important information.
A coulomb counter acts as a battery meter, tracking the energy consumption of the device. This enables an accurate battery percentage to be reported. The battery meter also allows accurate battery life predictions. Simply deploy the device in your application with the desired settings. The energy usage will be reported, enabling you to extrapolate to determine the battery life time.
