Abstract
Aspects of the subject disclosure may include, for example, computing a first location of a processing system, receiving first data via a unicast transport technology at a first rate, computing a first corrected location of the processing system in accordance with the first location and the first data, receiving second data via a broadcast transport technology, a multicast transport technology, or a combination thereof, at a second rate that is less than the first rate, and computing a second corrected location of the processing system in accordance with the second data. Other embodiments are disclosed.
Claims20
A method, comprising:
- receiving, by a first processing system including a processor, a plurality of signals from a plurality of satellites;
- computing, by the first processing system, a first location of the first processing system responsive to the receiving of the plurality of signals;
- receiving, by the first processing system, first error correction data from a second processing system that includes a second processor;
- applying, by the first processing system, the first error correction data to the first location to generate a first corrected location of the first processing system;
- receiving, by the first processing system, second error correction data from the second processing system via a broadcast transport technology, a multicast transport technology, or a combination thereof;
- and
- applying, by the first processing system, the second error correction data to the first corrected location of the first processing system to generate a second corrected location of the first processing system.
A device, comprising:
- a first processing system including a processor;
- and
- a memory that stores executable instructions that, when executed by the first processing system, facilitate performance of operations, the operations comprising:
- receiving positioning information;
- computing a first location of the first processing system, wherein the computing the first location is responsive to the receiving of the positioning information;
- receiving first error correction data from a second processing system, the second processing system including a second processor, wherein the first error correction data is received by the first processing system at a first rate of signaling;
- generating a first corrected location of the device based on the first error correction data and the first location;
- and
- receiving, at the device, second error correction data from the second processing system, wherein the receiving the second error correction data comprises receiving the second error correction data via a broadcast transport technology, a multicast transport technology, or a combination thereof.
A non-transitory, machine-readable medium, comprising executable instructions that, when executed by a first processing system including a first processor, facilitate performance of operations comprising:
- receiving a plurality of positioning signals;
- responsive to the receiving of the plurality of positioning signals, computing a first location of the first processing system;
- receiving, at a first rate of signaling, first error correction data from a second processing system that includes a second processor;
- adjusting the first location according to the first error correction data to generate a first corrected location of the first processing system;
- and
- receiving second error correction data from the second processing system via a broadcast transport technology, a multicast transport technology, or a combination thereof.
