Message
Description
MODE
1 = Ready to enter RTK ambiguity fix
0 = Not ready to enter RTK ambiguity fix
TYP
1 = Receiver running in RTK ambiguity fix mode
0 = Receiver not running in RTK ambiguity fix mode
AGE
Number of satellites used to fix
SUBOPT
summer-1 SS1 must be significantly larger than SS2 and SS3 to enter R=1 mode
DIST
summer-2
SYS
summer-3
NUM
Bit mask; bits identify which GNSS observables are being received from base recently (1 = GPS, 3 =
GPS + GLONASS)
SNR
Checksum
RSF
Carriage return
BSF
Line Feed
HAG
Horizontal accuracy guess
ACCSTAT
RTK accuracy status (hex), where:
•
0x1 = no differential or differential too old, for the application
•
0x2 = problems with differential message
•
0x4 = horizontal position estimate poor for the application
•
0x8 = HDOP high, poor satellite geometry
•
0x10 = fewer than 6 L1 satellites used
•
0x20 = poor L1 SNRs
•
0x40 = not in RTK mode
•
0x80 = not in RTK mode or RTK only recently solved (< 10 sec ago)
•
0x100 = RTK solution compromised, may fail
The status message can be any of the above or any combination of the above. For example, a status
message of '047' indicates the following:
•
0x1 = no differential or differential too old, for the application
•
0x2 = problems with differential message
•
0x4 = horizontal position estimate poor for the application
•
0x40 = not in RTK mode
SNT
Ionospheric scintillation, values are:
•
0 (little or no scintillation - does not adversely affect RTK solution)
•
1-100 (scintillation detected - adversely affects RTK solution)
