 GPSSeconds–CurrenttimeinGPSseconds.Incrementalnumberofseconds,startingat0hour
UTConthedateJanuary6,1980.
 Offset–Thedifferencebetweenthecurrenttimeasreportedbytheclockandthetime
derivedfromtheGPSpositionsolution.
 Drift–TherateatwhichthereceiverclockisdriftingfromthetimederivedfromtheGPS
positionsolution.
Multi‐systemclockoffsets–Showsinformationaboutthetimedifferencesbetweentheclocks
usedbydifferentsatellitesystems.
 MasterClockSystem–Thesatellitesystemclockbeingused
bythereceiver.
 GLONASSOffset–TheoffsetbetweenthemasterclockandtheGLONASSclockwhen
GLONASSsatellitesarebeingtracked.
 GLONASSDrift–TherateatwhichtheoffsetbetweenthemasterclockandtheGLONASS
clockischangingwhenGLONASS sate llitesarebeingtracked.
Velocity
–Showstheapparentvelocityofthereceiverderivedfromthedifferenceofthecurrent
positionrelativetothepreviousposition.
 North–Theapparentvelocityinthegridnorthdirection,inmeterspersecond.
 East–Theapparentvelocityinthegrideastdirection,inmeterspersecond.

 Up–Theapparentvelocityintheverticaldirection,inmeterspersecond.
{b}Note–{/b}Astationaryreceivershowssomevelocityduetominordifferencesintheposition
solutioneachtimeitiscomputed.Thereceivermustbemovingforthesevaluestobemeaningful
foranythingother
thangeneralstatusinformation.
ErrorEstimates(1‐Sigma)–Showsthevariationofthecurrentpositionwitha68%confidence.
 North–Theapparentvariationofthereceiverpositioninthegridnorthdirection,inmeters.
 East–Theapparentvariationofthereceiverpositioninthegrideast
direction,inmeters.
 Up–Theapparentvariationofthereceiverpositionintheverticaldirection,inmeters.
 SemiMajorAxis–Thesemimajoraxisoftheerrorellipse.
 SemiMinorAx is–Thesemiminoraxisoftheerrorellipse.
 Orientation– Theorientation
ofthemajoraxisoftheerrorellipse.
DilutionsofPrecision–Showsinformationaboutthestrengthofthesatelliteconstellationwith
respecttoaspecificpositionattribute.ThevariousDOPstakeintoaccountthelocationofeach
satelliterelativetoothersatellitesintheconstellation,aswellastheirlocation
relativetothe
receiver.LowDOPvaluesindicateahigherprobabilityofaccuracy.
 PDOP–PositionDOP,indicatesthestrengthofthesatelliteconstellationforgeneralposition
accuracy.
 HDOP–HorizontalDOP,indicatesthestrengthofthesatelliteconstellationforhorizontal
positionaccuracy.
 VDOP–VerticalDOP,
indicatesthestrengthofthesatelliteconstellationforverticalposition
accuracy.
