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 receiver    
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
