Satellites–GeneralInformation
Thispageshowsoverviewinformationaboutthesatellitesbeingtrackedandtheoverallsatellite
constellation.Theinformationonthisdisplayisupdatedeveryfiveseconds.
SatellitesTracked–ShowsthetotalcountandPRNnumbersofthesatellitescurrentlybeing
tracked.ThisdisplayincludesGPS,SBAS,OmniSTAR,GLONASS,Galileo.
TotalSatellites
in<name>Constellation–Showshowmanysatellitesarecurrentlyinorbitforthe
namedconstellation.
HealthySatellites–Showshowmanysatellitesarecurrentlythoughttobehealthy,thatis,fully
operational.Thisinformationcomesfromthemostrecentdatatransmittedinsatellitealmanacs.
UnhealthySatellites–Showshow
manysatellitesarecurrentlythoughttobeunhealthy.Typically,
unhealthysatelliteswillnotbetracked,measured,orusedinposition calculations.
Satellites–TrackingInformation(Tabl e)
Thistableshowsinformationaboutthesatellitesthatarecurrentlybeingtracked.Tosortthetable
basedoncolumnvalues,clicktheheaderatthetopofthecolumn.
IfthebackgroundcolorofagivenGPS,GLONASS,GalileoorSBASsatelliteisred,thesatelliteis
unhealthy.Datafrom
unhealthysatellitesisloggedbutisnotusedinthepos itionsolution.
Ifthebackgroundcolorofagivensatelliteonthetableisorange,thereceiversRAIM(Receiver
AutonomousIntegrityMonitoring)algorithmhaseitherdetectedaproblemwiththesatelliteor,if
youaretrackingSBAS,thecorrectionsindicate
thereisanintegrityproblemwiththesatellite.In
eithercase,thesatelliteisnotusedinthepositionsolution.
Alineofinformationshownwithabluebarindicatesthatthesatelliteistracked,butnotyetfully
phaselocked,soitisnotyetavailableforuseinRTK.
Thistypicallyoccursverybrieflywhena
satelliteisfirstacquiredorwhentheenvironmentishostiletoGNSS.
SV–Thenumericidentifierofthesatellitetrackedonthechannel.
Type–IndicatesifthesatelliteisGPS,GLONASS,WAAS/EGNOS,MSAS,GalileoorOmniSTAR.
Elev[Deg]–Theelevation
ofthesatellite,indegreesabovethehorizon.
Azim[Deg]–Theazimuth(direction)ofthesatellite,indegreesclockwisefromTrueNorth.
L1‐C/No[dBHz]/L2‐C/No[dBHz]/L5‐C/No[dBHz]–Thesignal‐to‐noiseratioofthesatelliteon
eithertheL1,L2,orL5frequency.
Scaledtoa1Hertzbandwidth.TheSNRsareavailableforboth
Positionantenna1(POS)andVectorantenna2(VECT)fordual‐antennasystems.
L1–TheL1carriersignalbeingtracked.IfCisdisplayed,theciviliancodeofthesatelliteisbeing

thePcodeofthesatelliteisbeingtracked(forGLONASSsatellites).
L2–TheL2carriersignalisbeingtracked.IfEisdisplayed,thereceiveristrackingtheL2carrier
waveusingthelegacytechnique.IfCisdisplayed,thereceiveristrackingtheL2carrierwaveusing
