G-Nut/Anubis - data pre-processing

When requested, Anubis performs carrier phase pre-processing which includes receiver clock jump detection and phase cycle-slip detection and estimation. Since version 1.3.0, Anubis checks carrier phase observations from all signals at all frequencies and all GNSS satellite constellations. Summary report is provided when set sec_pre="1" and the following informations are reported (see also listing below):

  • Clk_Jmp - number of receiver clock jumps
  • CS_Total - number of all phase cycle-slips and carrier-phase interruptions
  • CS_Slips - number of identified real phase cycle-slips during a continous phase tracking
  • CS_Epoch - number of carrier-phase interruptions due to missing epoch (counts all previously observed satellites and signals)
  • CS_Satell - number of carrier-phase interruptions due to temporary unavailable satellites
  • CS_Signal - number of carrier-phase interruptions due to temporary unavailable signals


Detail reports on clock jumps epochs and calculated phase cycle-slips are provided if set sec_pre="2".
Both lists are sorted by epochs and cycle slips provided with specific line for individual satellites while reporting all common signals.
