Adopting Bicomplex Numbers for GNSS Meta-Signal Processing

A 4D extension of complex numbers, bicomplex numbers allow for a compact representation of GNSS meta-signals with components from two different frequencies. Acquisition and tracking algorithms are obtained from the bicomplex signal representation, giving it potential for effective dual-frequency GNSS signal processing.

Q: How can two-way communications between reference stations and users enhance the performance and integrity  of differential GNSS navigation?

JIYUN LEE, GIHUN NAM AND K. ANDREW SUN, KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY (KAIST)

A: Many forms of differential GNSS (DGNSS) exist to provide GNSS users with corrections to their pseudorange and carrier-phase measurements along with information to support their applications and provide integrity assurance [1].
