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 Oyster 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 Oyster uses 3 x “AA” size 1.5V Lithium batteries which provide a balance between size and capacity
The Oyster Cellular must be fitted with off-the-shelf 1.5V Lithium batteries. These are readily available from retail outlets, for example Energizer Ultimate Lithium.
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.
4 years @ one position per day (at 25°C).
-20°C to +60°C
For operation in extreme temperatures, the Oyster must be fitted with Lithium 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 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 (LNA)
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!
The Oyster Cellular can be manufactured for specific markets around the world depending on their modem requirements:

Internal GPS and Cellular 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 assets being dropped or involved in accidents)
The Oyster has enough flash to store over 25,000 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.
