Abstract
A receiver for receiving a navigation signal comprising a carrier modulated by a code modulation function of a given code rate and further modulated by a composite sub-carrier modulation function having first and second components with two different rates both of which arc different to the code rate, the receiver comprising processing means arranged to: generate a first estimate of delay based on the code modulation only; generate a second estimate of delay based on the first component of the sub-carrier modulation only; and generate a third estimate of delay based on the second component of the sub-carrier modulation only; and determine a further delay estimate from the first second and third delay estimates.

A receiver for receiving a navigation signal comprising a carrier modulated by a code modulation function of a given code rate and further modulated by a composite sub-carrier modulation function having first and second components with two different rates both of which are different to the code rate, the receiver comprising a processor arranged to:
- generate a first estimate of delay based on the code modulation only;
- generate a second estimate of delay based on the first component of the sub-carrier modulation only;
- and
- generate a third estimate of delay based on the second component of the sub-carrier modulation only;
- and
- determine a further delay estimate from the first second and third delay estimates.

A receiver for receiving a navigation signal comprising a carrier modulated by a code modulation function of a given code rate and further modulated by a composite sub-carrier modulation function having first and second components with two different rates both of which are different to the code rate, the receiver comprising processor arranged to:
- generate independently first, second and third estimates of delay based on the code modulation, the first component of the sub-carrier modulation, and the second component of the sub-carrier modulation respectively;
- and
- determine a further delay estimate from the first second and third delay estimates.
