The fact that a large Gabor bandwidth promotes measurement accuracy has motivated research on Global Navigation Satellite System (GNSS) meta-signals, which are obtained by jointly processing components from different frequencies. When two side-band components are considered, the resulting meta-signal has characteristics close to that of a pure carrier and measurement ambiguities can arise: a third signal in between side-band components can alleviate this problem and help estimating the integer ambiguities. This paper provides a framework for the generation of measurements from triple-component GNSS meta-signals with the goal of reducing the ambiguity problem. The whole meta-signal is at first decomposed as two dual-component meta-signals with the central component used as pivot. Measurements on the dual-component meta-signals are computed using the synthetic approach based on the Hatch-Melbourne-Wübbena (HMW) combination. Triple-component pseudoranges are then obtained as the narrow lane combination of the pseudoranges from the dual-component meta-signals. Theoretical results have been supported through experimental analyses based on measurements from two Septentrio PolaRx5S multi-frequency, multi-constellation receivers set up in a zero-baseline configuration. Results based on the Galileo E5a, E5b and E6 components show the effectiveness of the proposed framework.
