GNSS Signals in the improved TRIUMPH-LS with the new chip

摘要

GNSS bands for GPS, GLONASS, Galileo and BeiDou signals are depicted in the above figure. There are total of 22 signals in 17 frequency bands labeled "a" to "q". Note that GPS C/A, L1C and P1 are in the same band (m) and GLONASS CA/L2 and P2 also are in the same band (d) of the same satellite. In selecting signals for RTK processing, as an option, we may choose to select only one of such signals in the same band. We label this option as "No Same Frequency" option in signal selection strategy screen, discussed later.
