Photo: Quectel Quectel Wireless Solutions has published a new white paper titled “Why GNSS for eMobility must balance precision, price, power and packaging.” According to Quectel, this paper details the challenges eMobility providers face in enabling vehicles such as eScooters and eBikes to be located in deep urban canyons. The white paper also examines why accurate location data will be vital in enabling the ride-sharing industry to comply with regulation to restrict eMobility usage on sidewalks and other areas, Quectel said. The report also details drive test data conducted on an eScooter in San Francisco. The data demonstrates the enhanced accuracy offered by L1 and L5 plus dead reckoning capability. Finally, the white paper discusses how the Quectel LC79D is enabling the eMobility industry to harness the fusion of different sensors in a very small footprint at low incremental cost with unparalleled accuracy, the company added. “eMobility providers face substantial challenges when dealing with location in deep urban environments,” said Mark Murray, vice president of sales for GNSS and automotive at Quectel. “First and foremost, customers need to be able to find the vehicle and cities need to have the assurances that these eBikes and eScooters are operated in mutually agreed locations.”
