u-blox A-GNSS services
GNSS devices often struggle with long startup times and high power drain—especially in urban areas or when signals are weak. AssistNow solves this by delivering satellite orbital data directly to the GNSS receiver over the internet, enabling near-instant position fixes even under poor signal conditions. This reduces time-to-first-fix (TTFF), improves reliability, and extends battery life—critical for compact, energy-constrained IoT devices that need to operate for months or years without intervention.
Whether your device is tracking vehicles, people, or pets, it needs to perform reliably across varied environments—including dense cities and indoor-to-outdoor transitions. AssistNow ensures your device gets the best possible fix, with options like free Predictive Orbits or premium Live Orbits to meet accuracy and energy needs. Developers can easily test performance with u-center 2, our powerful Windows tool for GNSS configuration and evaluation.
With AssistNow Predictive Orbits, users download u-blox's orbit prediction data and almanac of the GNSS satellites from the Internet at their convenience using HTTPS protocol. The data can either be stored in the GNSS receiver’s Flash EPROM (if available) or in the memory of the application processor.
With AssistNow Live Orbits, an internet-connected device downloads GNSS assistance data every 2-4 hours. The service works on all standard mobile communication networks and no special arrangements with mobile network operators are needed.
