Get Position Response Fields    
Field Entry (4)     Definition    
00 00     GPS weak – not supplied by the MS980    
00 000000     GPS time (in milliseconds) – not supplied by the MS980    
09     Number of satellites used by the selected antenna    
Fixed     Receiver mode (may be Old, Autonomous, DGPS, Float or Fixed    
704905.345     Northing (m)    
289001.275     Easting (m)    
29.175     Vertical (m)    
1.8     PDOP (only appears 20% of the time) (5)    
( 4 ) The entries in these fields will vary.
( 5 ) PDOP is only reported once a second and positions 5 times a second, so on average you will only get PDOP 1 in every 5 tries.Get Details

Field Entry (6)     Definition    
L1OK     L1 RF status. Either L1OK or L1 is Bad    
L2OK     L2 RF status. Either L2OK or L2 is Bad    
field 3     Total number of GPS channels is not reported by the MS980s    
fields 4 - 15     Antenna tracking status is not reported by MS980s    
RSI OK     Reference station information. RSIOK or NORSI.    
254,254,254     Radio data link integrity over the previous 100, 1000 and 10000 seconds (corresponds to the 100s, 15min and 3hrs fields under the "Data Link" screen). The range for these values is 0 to 255 where 255 is equal to 100%.    
8     For the left receiver, this is the number of common L1 satellites that are between the base station and the left receiver. For the right receiver, this is the number of common L1 satellites between the left receiver and the right receiver.    
7     For the left receiver, this is the number of common L2 satellites between the base station and the left receiver. For the right receiver, this is the number of common L2 satellites between the left receiver and the right receiver.    
0.2s     The average latency of the radio link, in seconds.    
RTK     The current differential processing state for the left receiver. "NONE", "DGPS" or "RTK".    
0     The number of satellites used by the selected receiver for differential processing.    
0     Current receiver RTK position status codes are as follows:
0 – OK
1 – Insufficient satellites
2 – High differential PDOP
64 – Cannot synchronize
65 – No reference data
66 – No reference position
67 – Insufficient common satellites
68 – Bad reference satellite
69 – C/A, P-code mismatch
70 – High PDOP
128 – No L2 phase
135 – Low search ratio (normal during the initialization process)
136 – Propagation
