GPS (global positioning system)

ambiguity resolution

Telecommunications; GPS (global positioning system)

If the initial integer ambiguity value for each satellite-receiver pair could be determined, then the ambiguous integrated carrier phase measurement can be corrected to create an unambiguous, but ...

analog signal

Telecommunications; GPS (global positioning system)

The principal feature of analog signals is that they are continuous. In contrast, digital signals consist of values measured at discrete intervals.

That part of the GPS receiver hardware which receives (and sometimes amplifies) the incoming L-Band signal. Antennas come in all shapes and sizes, but most these days use so-called "microstrip" or ...

antenna splitter

Telecommunications; GPS (global positioning system)

An attachment which can be used to split the antenna signal into two, so that it may be fed to two GPS receivers. Such a configuration forms the basis of a Zero Baseline test.

anti-spoofing

Telecommunications; GPS (global positioning system)

Encryption of the P-code to protect the P-signals from being "spoofed" through the transmission of false GPS signals by an adversary.

anywhere fix

Telecommunications; GPS (global positioning system)

The ability of a receiver to start position calculations without being given an approximate location and time.

atomic clock

Telecommunications; GPS (global positioning system)

A very precise clock that operates using the elements cesium or rubidium. A cesium clock has an error of one second per million years. GPS satellites contain multiple cesium and rubidium clocks.
