First Claim
Patent Images
1. A method for providing signaling used for position determination in a positioning system, the method comprising:
- generating a first range block at a first transmitter, wherein the first range block includes a first ranging signal;
sending the first range block from the first transmitter in a first predefined slot of a plurality of predefined slots of a first transmit frame;
generating a first hybrid block at the first transmitter, wherein the first hybrid block includes a first positioning signal with positioning data that includes data specifying a location of the first transmitter or data specifying a pressure; and
sending the first hybrid block from the first transmitter in a second transmit frame that is disjoint from the first transmit frame.

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.
