Enhanced indoor positioning for location services

A method for determining one or more positions of a device, the method comprising:

• determining, by one or more processors, the device is located within an indoor environment;
• determining, by the one or more processors based on determining the device is located within the indoor environment, an updated horizontal uncertainty for the device is equal to an average of measurement errors of signals from a plurality of satellite vehicles (SVs);
• determining, by the one or more processors based on determining the device is located within the indoor environment, external positioning assistance data for the device has a reliability greater than one of a first reliability threshold or a second reliability threshold;
• determining, by the one or more processors based on determining the external positioning assistance data for the device has the reliability greater than at least one of the first reliability threshold or the second reliability threshold, a number of the SVs of the plurality of SVs is greater than or equal to a first threshold number of SVs;
• and
• determining, by the one or more processors based on determining the number of SVs of the plurality of SVs is greater than or equal to the first threshold number of SVs, the one or more positions for the device based on the updated horizontal uncertainty for the device and a horizontal uncertainty for the device from the external positioning assistance data for the device.

A non-transitory computer-readable medium having stored thereon instructions that, when executed by at least one processor, cause the at least one processor to:

• determine a device is located within an indoor environment;
• determine, based on determining the device is located within the indoor environment, an updated horizontal uncertainty for the device is equal to an average of measurement errors of signals from a plurality of satellite vehicles (SVs);
• determine, based on determining the device is located within the indoor environment, external positioning assistance data for the device has a reliability greater than one of a first reliability threshold or a second reliability threshold;
• determine, based on determining the external positioning assistance data for the device has the reliability greater than at least one of the first reliability threshold or the second reliability threshold, a number of SVs of the plurality of SVs is greater than or equal to a first threshold number of SVs;
• and
• determine, based on determining the number of SVs of the plurality of SVs is greater than or equal to the first threshold number of SVs, the one or more positions for the device based on the updated horizontal uncertainty for the device and a horizontal uncertainty for the device from the external positioning assistance data for the device.
