|Definition||This quality indicator gives information on the transmitter in terms of two digits, X and Y. X is the first digit and indicates residual error on the frequency calculation; Y is the second digit and indicates transmitter oscillator frequency drift between two satellite passes. Values provided in Argos diagnostic data (definition from Argos User's Manual 2011). Values obtained through some Argos channels do not include leading 0s, so 1-digit values indicate X = 0 and blank values or values of '0' indicate both X and Y = 0. Allowed values are X = 0: No calculation of residual frequency error (fewer than four messages received); X = 1,2,3: Unsatisfactory convergence of calculation; X = 4: Residual frequency error > 1.5 Hz; X = 5: 0.15 Hz < residual frequency error < 1.5 Hz; X = 6: Residual frequency error < 0.15 Hz; Y = 0: No check on transmit frequency drift, as the two results are more than 12 hours apart; Y = 1: Frequency discrepancy > 400 Hz Probably due to transmit frequency discrepancy, change of oscillator, etc; Y = 2: Previous location is less than 1/2 hour old. Frequency discrepancy > 30 Hz, i.e. F/F (over 10 min) >2.5 E-8; Y = 3: Frequency drift > 4 Hz/minute, i.e. F/F (10 min) > 1.10-7; Y = 4: Frequency drift < 4 Hz/minute, i.e. F/F (10 min) < 1.10-7; Y = 5: Frequency drift < 2 Hz/minute, i.e. F/F (10 min) < 5.10-8; Y = 6: Frequency drift < 1 Hz/minute, i.e. F/F (10 min) < 2.5 . 10-8; Y = 7: Frequency drift < 0.4 Hz/minute, i.e. F/F (10 min) < 1.10-8; Y = 8: Frequency drift < 0.2 Hz/minute, i.e. F/F (10 min) < 5.10-9.
