Why compromise?

The landscape of standard precision GNSS has been defined by compromise. Device manufacturers have had to choose between battery life and positioning accuracy, between dual-band capability and power efficiency. For wearables, asset trackers, and telematics applications where every milliwatt counts, this trade-off has constrained what's possible.

What is Selective L5 band technology?

The u-blox F11 changes this equation. It's the first situational-aware GNSS platform to combine truly ultra-low power operation with intelligent signal management, seamlessly adapting its use of L1 and L5 frequencies based on real-time environmental conditions. When open sky conditions provide sufficient accuracy with L1 alone, the platform conserves energy. When signal challenges emerge (urban canyons, dense foliage, indoor-outdoor transitions) the F11 engages L5 to maintain positioning reliability. This situational awareness eliminates the traditional accuracy-versus-battery-life compromise.

This intelligent approach delivers dual-band accuracy with near single-band power consumption, enabling:

Meter-level positioning in all environments
Up to 70% average power reduction versus continuous dual-band
Multi-year battery life for asset tracking
Enhanced accuracy in challenging conditions

Dual-band GNSS traditionally requires continuous L5 processing, consuming 35-50 mW. F11's Selective L5 mode activates L5 only when signal conditions improve positioning accuracy, delivering dual-band accuracy at near single-band power consumption. Up to 50% average power reduction versus continuous dual-band operation. This single innovation extends asset tracker battery life from months to years.

Introducing Positioning engine firmware (SPG 7.0x) features

The SPG 7.0x firmware represents a comprehensive positioning engine optimized for ultra-low power operation without compromising accuracy or reliability. It integrates advanced signal processing capabilities including multipath mitigation, intelligent L5 band management, and dynamic profile selection to adapt to diverse real-world environments and use cases. Through features like LEAP mode, indoor detection, geofencing, and ionospheric corrections, SPG 7.0x delivers intelligent positioning that balances power consumption and accuracy based on application requirements and signal conditions.

Power saving

Battery life defines success in wearables, trackers, and telematics applications. SPG 7.0x introduces intelligent power management capabilities that dramatically extend operation time without sacrificing positioning reliability. Through context-aware features like LEAP mode, indoor detection, geofencing, and long-interval tracking, the positioning engine adapts power consumption to real-world conditions - conserving energy when full GNSS capability isn't required while maintaining accuracy when it matters most.

For asset trackers operating intermittently, first-fix accuracy is critical. F11 achieves meter-level accuracy within 30 seconds with 40% lower power during signal acquisition - dramatically reducing GNSS on-time and extending battery life from months to multi-year deployments.

Position accuracy

Challenging environments like urban canyons, forest cover, and indoor-outdoor transitions demand robust signal processing to maintain reliable positioning. SPG 7.0x delivers enhanced accuracy through advanced multipath mitigation and intelligent L5 activation, improved first-fix performance, ionospheric corrections, and specialized dynamic profiles optimized for specific use cases. These capabilities ensure consistent meter-level accuracy across diverse operating conditions, from continuous wearable tracking to periodic asset monitoring.

Security

As positioning data becomes critical for safety, fleet management, and asset protection, signal integrity cannot be compromised. SPG 7.0x incorporates sophisticated spoofing detection and mitigation algorithms that identify false satellite signals and maintain positioning reliability even under deliberate interference. Support for authenticated GNSS signals and L5-only operation under L1 jamming conditions provides defense-in-depth protection for applications where trustworthy location data is essential.
