First Claim
Patent Images
1. A method comprising:
- causing, by a configured processor, a broadcast of positioning assistance data in a plurality of different logical sub-channels, wherein the positioning assistance data has been distributed to the plurality of different logical sub-channels depending on its content such that a respective different logical sub-channel is provided for at least one of;
orbit and clock models as broadcast by satellites of at least one global navigation satellite system and high-accuracy orbit and clock models;
each of a plurality of regional ionosphere models and one of an ionosphere model as broadcast by satellites of at least one global navigation satellite system and ionosphere maps for continent-wide models;
a cell identifier database for a first country and a cell identifier database for a second country; and
each of a plurality of service quality levels of the assistance data, wherein different service quality levels include at least one of different accuracies and different resolutions of the assistance data.
