The GPS carrier-phase ambiguity problem will be
considered, first with the existing two frequencies at 1575.42
MHz. And 1227.6 MHz. And then with the addition of the newly
proposed third frequency at 1176.45 MHz. Special emphases will
be placed on understanding the benefits and limitations of forming
various linear combinations of the measurements. A discussion
of what a better third frequency or even a fourth frequency
could provide will also be included. The factors, which limit
the baseline separation distance between reference and user
receivers, will also be addressed and methods for extending
the baseline distances will be discussed.
