u-blox' proprietary anti-jamming technology

GPS satellites are typically 20,000 km away, and from this great distance transmit signals with the equivalent power of a weak light bulb. It is therefore critical when selecting a GPS receiver to choose one with high sensitivity to GPS signals as well as high immunity to interfering signals and other radio-frequency noise. The ability to lock onto faint GPS signals in the presence of interfering signals and noisy devices such as mobile phones, music players, PDAs, PC bus and automotive electronics has a significant influence on the system’s ability to reliably provide accurate location data. The interference produced by nearby devices can actually jam a GPS receiver.

u-blox 5 GPS positioning engines achieve best-in-class performance in noisy environments through an advanced, proprietary adaptive digital filtering technology which actively suppresses interference. This solution has been proven in overcoming interfering signals up to 25 dBm stronger than conventional GPS receivers can withstand. The result is the most sensitive and reliable GPS receiver technology on the market.
    
u-blox’ proprietary anti-jamming technology gives GPS equipment manufacturers the following benefits:
  • Delivers consistent GPS operation in noisy urban environments and indoors, well past the point where conventional systems fail
  • Allows embedding of the GPS receiver in close proximity to RF noise sources: in mobile phones, mobile computers, PNDs, and automotive dashboards
  • Compatible with small, low cost antennas
  • Small surface mount GPS receiver modules requiring little space
  • Tested, off-the-shelf solutions
  • Cost-effective
