Abstract
Devices, systems, and methods for sending positional information from transmitters/beacons. In one implementation a transmitter generates a range block including a ranging signal and a hybrid block including positioning data, and sends the range block and hybrid block at different times. A user device may receive signals from a plurality of transmitters and generates position/location information using trilateration and measured altitude information in comparison with transmitter altitude information.

A method for receiving signaling used for position determination in a positioning system, the method comprising:
- receiving, from a first transmitter, a first range block that includes a first ranging signal,
- wherein the first range block was generated by the first transmitter and transmitted from the first transmitter in a first predefined slot of a plurality of predefined slots of a first transmit frame;
- and
- receiving, from the first transmitter, a first hybrid block that includes a first positioning signal with positioning data that includes data specifying a location of the first transmitter or data specifying a pressure,
- wherein the first hybrid block was generated by the first transmitter and transmitted from the first transmitter in a second transmit frame that is disjoint from the first transmit frame.
One or more non-transitory computer-readable media embodying program instructions that, when executed by one or more processors, cause the one or more processors to perform a method for providing signaling used for position determination in a positioning system, the method comprising:
- receiving, from a first transmitter, a first range block that includes a first ranging signal,
- wherein the first range block was generated by the first transmitter and transmitted from the first transmitter in a first predefined slot of a plurality of predefined slots of a first transmit frame;
- and
- receiving, from the first transmitter, a first hybrid block that includes a first positioning signal with positioning data that includes data specifying a location of the first transmitter or data specifying a pressure,
- wherein the first hybrid block was generated by the first transmitter and transmitted from the first transmitter in a second transmit frame that is disjoint from the first transmit frame.
