Banebrydende GNSS receiver-chip til wearables
u-blox lancerer ny GNSS-receiver chip, UBX-M8230-CT, der understøtter en såkaldte Super-Efficient (Super-E) mode, der sikrer hidtil uset lavt effektforbrug (in english).
u-blox has announced the launch a new global navigation satellite system, GNSS, receiver chip, UBX-M8230-CT, that offers a unique balance of performance and ultra-low power use.The new, innovative Super-Efficient (Super E) mode cuts the power consumption by two-thirds to a mere 20mW at one position update every second with hardly any loss in accuracy. It delivers continued superb speed and position accuracy even when tested in applications such as wearables and portable electronics, where the antenna is small and movement prevents a constant view of the sky.
Ideal combination for portable and wearable devices The Super-E mode is ideal for devices that require high levels of speed and position accuracy, but where power is limited. Along with smartwatches, sports wearables and fitness trackers, it can be used in trackers for assets, people, children and animals, to provide accurate and frequent location information with minimal impact on battery life.
- Constantly needing to know the user location in wearables has a strong strain on the battery, which has traditionally limited GNSS adoption. UBX-M8230-CT’s low power consumption combined with its high positioning accuracy and the ultra small design footprint of less than 30 mm2 makes it possible to add GNSS to virtually all wearables, explains Florian Bousquet, Market Development Manager, Product Center Positioning at u-blox.
He adds:
- The UBX-M8230-CT’s Super-E mode uses concurrent reception of GPS with either GLONASS or BeiDou. It allows batching location data temporarily on the chip, which helps to further reduce the system power consumption by avoiding the need to constantly run the main CPU.
