Abstract
The cellular device accesses a GPS/GNSS chipset embedded within the cellular device. The GPS/GNSS chipset calculates pseudorange information for use by the GPS/GNSS chipset. The cellular device extracts the pseudorange information from the GPS/GNSS chipset for use elsewhere in the cellular device outside of the GPS/GNSS chipset.
Claims35
A method of obtaining pseudorange information using a cellular device, the method comprising;
- sending, performed by the cellular device, a message to a Global Positioning System/Global Navigation Satellite System (GPS/GNSS) chipset embedded within the cellular device to initiate an E911 activity, wherein the GPS/GNSS chipset calculates pseudorange information for use by the GPS/GNSS chipset;
- receiving, performed by the cellular device, the pseudorange information from the GPS/GNSS chipset for use elsewhere in the cellular device outside of the GPS/GNSS chipset, the pseudorange information provided by the E911 activity;
- and
- sending, performed by the cellular device, a message to the GPS/GNSS chipset to cancel the E911 activity before transmission of the pseudorange information external to the cellular device.
A non-transitory computer readable storage medium comprising instructions, which when executed causes a processor of a cellular device, which is not a part of an embedded Global Positioning System/Global Navigation Satellite System (GPS/GNSS) receiver of the cellular device, to perform a method for obtaining pseudorange information using a cellular device, the method comprising:
- sending, performed by the cellular device, a message to a Global Positioning System/Global Navigation Satellite System (GPS/GNSS) chipset embedded within the cellular device to initiate an E911 activity, wherein the GPS/GNSS chipset calculates pseudorange information for use by the GPS/GNSS chipset;
- receiving, performed by the cellular device, the pseudorange information from the GPS/GNSS chipset for use elsewhere in the cellular device outside of the GPS/GNSS chipset, the pseudorange information provided by the E911 activity;
- and
- sending, performed by the cellular device, a message to the GPS/GNSS chipset to cancel the E911 activity before transmission of the pseudorange information external to the cellular device.
