3 Description

The u-blox EVK-M102 has reached Engineering Sample (ES) status. The EVK-M102 is built on the u-blox M10 single-band GNSS technology, now available as a firmware-upgradable chip. The new firmware introduces a new low energy accurate positioning (LEAP) mode, reducing power by 50% while maintaining solid meter-level position accuracy.

The EVK-M102 received the capability to output GNSS receiver power consumption, which can be visualized live in u-center 2, making it easy to evaluate power consumption in different modes of operation.

Additionally, different types of GNSS aiding services can be evaluated to achieve better performance:

AssistNow Live Obits	Faster time to first fix (TTFF)
AssistNow Predictive Orbits	Improved positioning accuracy
	Faster time to first fix (TTFF)

4 Schedule

EVK-M102 Engineering Samples are available from August 2025 onwards.
