Precise positioning correction service determination

An apparatus comprising:

• at least one memory;
• at least one transceiver;
• and
• at least one processor communicatively coupled to the at least one memory and the at least one transceiver and configured to:
• receive, via the at least one transceiver, crowdsourced SPS correction information indicating:
• (1) a location corresponding to the crowdsourced SPS correction information;
• (2) a plurality of SPS correction services;
• (3) at least one SPS correction for each of the plurality of SPS correction services;
• and (4) at least one respective correction service characteristic for each of at least one of the plurality of SPS correction services;
• obtain a position estimate for a mobile wireless device, the position estimate for the mobile wireless device comprising one of a present position estimate for the mobile wireless device or a future position estimate for the mobile wireless device;
• and
• indicate, based on the position estimate, which of the plurality of SPS correction services are available for the mobile wireless device to use to correct at least one SPS signal received by the mobile wireless device to determine an SPS-signal-corrected position estimate for the mobile wireless device.

A method of crowdsourcing satellite positioning system (SPS) correction data, the method comprising:

• receiving, at a mobile wireless device, at least one SPS correction provided by an SPS correction service of a plurality of SPS correction services;
• determining, at the mobile wireless device, a position estimate for the mobile wireless device based on the at least one SPS correction;
• and
• transmitting, from the mobile wireless device, a correction service message indicating:
• (1) a location corresponding to the position estimate for the mobile wireless device;
• (2) the SPS correction service;
• and (3) at least one correction service characteristic for each of at least one of the plurality of SPS correction services.

A mobile wireless device comprising:

• at least one memory;
• at least one transceiver;
• and
• at least one processor communicatively coupled to the at least one memory and the at least one transceiver and configured to:
• receive, via the at least one transceiver, at least one SPS correction provided by an SPS correction service of a plurality of SPS correction services;
• determine a position estimate for the mobile wireless device based on the at least one SPS correction;
• and
• transmit, via the at least one transceiver, a correction service message indicating:
• (1) a location corresponding to the position estimate for the mobile wireless device;
• (2) the SPS correction service;
• and (3) at least one correction service characteristic for each of at least one of the plurality of SPS correction services.
