PANEL: ADVANCES AND CHALLENGES IN INTEGRATING MULTI-BAND SATNAV IN NEXT-GENERATION SMARTPHONES AND PORTABLE DEVICES
(Presentations by invitation only)
Dual frequency satnav is becoming commonplace in most flagship smartphones in 2021. A decade ago, the 20 MHz bandwidth, miniaturized antennas, and processing power needed to support signals in the L5/E5 band was thought to be impossible for a smartphone. Yet here we are! Innovation has not stopped, and neither have the challenges. How did we get here? What were the key technical challenges and how were they solved? Today, smartphones handle 100+ MHz of bandwidth for 5G. Can we expect to see future phones or augmented reality glasses supporting the 50 MHz AltBOC signals? Or, do they call for a completely new GNSS solution – like LEO-GNSS? What type of performance will that provide, and which sensor fusion strategy (inertial, optical) will apply? What new applications will this enable? Our panel of experts will discuss these and other exciting developments in smartphone satnav technology. Come prepared to get a glimpse of what the future holds!
