LEAP: Low Energy Accurate Positioning for Wearables

Maximise Positioning Accuracy and Battery Life in Next-Generation Wearables

As wearable devices become essential for health, fitness and navigation, the demand for precise positioning grows. However, achieving reliable GNSS accuracy in compact, battery-limited devices remains a challenge.

To solve this, u-blox introduces LEAP (Low Energy Accurate Positioning) — a breakthrough GNSS technology built on the u-blox M10 platform. LEAP delivers consistently accurate positioning while significantly extending battery life. This makes it perfect for smartwatches, fitness trackers and sports wearables.

Solving the Power-Performance Dilemma

Traditionally, low-power GNSS modes sacrifice accuracy. In tough environments like urban canyons, forests, or mountains, weak satellite signals and noise can degrade performance. Devices then drain batteries trying harder to maintain fixes.

LEAP changes this by using smarter signal processing. Instead of handling every signal, it selectively chooses the highest-quality ones. By filtering out noisy signals, it reduces power use and improves accuracy.

Furthermore, LEAP includes real-time external low-noise amplifier (LNA) switching. It evaluates signal strength on the fly and powers the LNA only when needed. This avoids wasting energy.

Optimised for Movement and Real-World Use

LEAP is designed specifically for wearables. It features activity-aware dynamics — motion models customised for running, cycling and hiking. These models help the GNSS system understand user movement better. It compensates for arm swings and stride changes, resulting in more accurate paths.

In real tests, LEAP saved up to 50% power compared to standard GNSS modes. At the same time, it delivered equal or better accuracy. For example, in forests, LEAP achieved a CEP95 of 8 meters — much better than the 14 meters from other solutions. In open skies, accuracy improved from 4 meters to just 2.

Built for the Future of Wearables

LEAP’s compact chip (2.39 x 2.39 mm) fits into the smallest devices. It supports firmware upgrades through external flash or a connected MCU, keeping devices up to date.

Additionally, LEAP works with Android, u-blox AssistNow for faster time-to-first-fix, and positioning protocols like SUPL. This ensures smooth integration into connected ecosystems.

A Leap Forward in GNSS Technology

By combining low power consumption with strong accuracy, LEAP enables smarter, more efficient wearables. Whether building a rugged GPS sports watch or a sleek fitness tracker, LEAP gives your design a competitive edge.
