Technology: Under 1 second time-to-first-fix


Fastest acquisition performance in the GPS market

u-blox 5 boasts the fastest acquisition engine in the GPS market. The u-blox 5 chip is composed of two separate engines, one devoted exclusively to acquisition and one correlator engine for tracking. With over 1 million correlators, the dedicated acquisition engine is capable of massively parallel searches.
  • 50 Channels
  • Over 1 million correlators
  • Simultaneously receives GPS, WAAS, EGNOS, MSAS and Galileo satellites

Overall, u-blox' fifth generation chip boasts a 50-channel architecture that enables satellite acquisition in less than 1 second and -160 dBm acquisition and tracking sensitivity.


A-GPS performance standards

Additionally, u-blox 5 greatly greatly exceeds the minimum requirements for the following A-GPS performance standards:
  • E-911 Phase II
  • UMTS / GSM: 3GPP TS 25.171
  • CDMA: TIA.916


Spontaneous acquisition

Under good signal conditions, satellites are all acquired within the first second, from the moment you switch on the u-blox 5 receiver, as depicted in the screenshot.
