Abstract
A method for locating at least one receiver in a positioning system. The system includes: at least two generators, each generator emitting, on a single carrier, at least two signals that each have a different code, and a receiver configured to detect the signals emitted by the generators. In the method: the receiver measures, for each generator, the phase difference between both signals emitted by the generator, and at least one geometric size, representing the position of the receiver in relation to the generators, is calculated on the basis of the measurements of the phase difference in order to locate the receiver in the positioning system.

A method for locating at least one receiver within a positioning system, the system comprising:
- at least two generators, each generator emitting, on one and the same carrier, at least two signals each having a different code, and
- a receiver configured to detect the signals emitted by the generators,
- in which method:
- the receiver measures, for each of the generators, the phase difference between the two signals emitted by the generator, and
- depending on these phase difference measurements, at least one geometric quantity is calculated that is representative of the position of the receiver with respect to the generators in order to locate the receiver within the positioning system.
A positioning system, including:
- at least two generators, each generator emitting, on one and the same carrier, at least two signals each having a different code, and
- a receiver detecting the signals emitted by the generators,
- the system being configured such that:
- the receiver measures, for each of the generators, the phase difference between the two signals emitted by the generator, and
- depending on these phase difference measurements, at east one geometric quantity representative of the position of the receiver with respect to the generators is calculated in order to locate the receiver within the positioning system.
A receiver intended to be used within a positioning system comprising at least two generators, each generator emitting, on one and the same carrier, at least two signals each having a different code, the receiver detecting the signals emitted by the generators,
- the receiver being configured:
- to measure, for each of the generators, the phase difference between the two signals emitted by the generator, and
- such that, depending on these phase difference measurements, at least one geometric quantity representative of the position of the receiver with respect to the generators is calculated in order to locate the receiver within the positioning system.
A generator intended to be used within a positioning system, said system comprising at least one other generator and a receiver configured to detect the signals emitted by said generator and the other generator, said generator being configured to emit, on one and the same carrier, at least two signals each having a different code, the receiver being configured to measure the phase difference between said two signals emitted by the generator.
