Ultra-low-power positioning for battery-powered mobile devices

GNSS sensors are embedded in billions of devices to provide position, velocity, and time. GNSS sensors consume a lot of battery power, 10x higher than typical accelerometers. Battery life of mobile devices is significantly shortened when GPS is turned on. For example, A typical fitness band with a 70mAh battery can last up to 2 weeks without charging. However, when GPS is turned on, this same device would last for only 3 to 5 hours, barely enough for a marathon.

In fact, current existing GNSS sensors could reduce their power consumption at the price of providing a not-so-accurate positioning result. Yet, these very large positioning errors will certainly impede user experience and will not be very useful in practice. Kolmostar’s ultra-low-power GNSS solution is able to reduce the power consumption of GNSS sensors by up to 150x while still maintain the same level of positioning accuracy. This creates an opportunity to add GNSS sensors to any moving objects you want, without worrying about battery life at all.

All these generated data supports various applications, such as sharing economy. The data will also be used by AI to better understand the world and make our life more convenient.
