2. WhydoesGSMfailtocommunicate?
CheckiftheSIMcardisopened
CheckwhethertheSIMcardhaspassword
CheckiftheSIMcardiscorrectlyplaced.
MakesuretheSIMcarddoessupportGSMfunction.
Makesuretocutoffpower,beforepullingouttheSIMcard.
IfthevehicleisparkedinaplacewheretheGSMsignalisweak.
GSMbasestationofmobileoperatoriscrashing.
WhetherthisSIMcardissuspended(suchasforgettopaythebill…)

3. WhyGPScannotcalculatetheposition?
CheckifGPSantennaiscorrectlyinstalled,orifitisplacedinaproperposition.
Makesurethereisnotbeanymetalshield,suchaswindshieldheatinsulationpaper
withmetalliccontent,abovetheGPSantenna‐whichmayblockthereceptionof
GPSsignal.

Donotparkyourvehicleundershieldingorunderabuilding.

Ifnecessary,puttheGPSantennaoutsidethevehicletemporarily.

4. WhydoesGPSpositioningtakesuchalongtime?

Thetimeusedforpositioningisaffectedbymanyfactors,suchastheweather,
distributionofclouds,roadsidetrees,elevatedroads,nearbyhighbuildings,heat
insulatingpaperscontainingmetalelements,andeventhecoveringofthehands,
mayaffectthereceptioneffectofsatellitesignals.Positioningavehicleinanidle
statetakelesstimethanpositioningitinmotionstate.

5. DoestheweatheraffectGPSoperation?

GPSsystemisabletoovercomeweatherprobleminitsinitialdesign.GPSsatellite
positioningsignalsconsistofshortwaves;thetransmissionofshortwaveswillnot
beaffectedbyweatherconditions.GPSsignalsmayproduceerrorfactorsduring
transmission,suchassolarwind,earthrotation,andvariationofaerospheredensity,
buildingreflection,etc.AllofwhichmaycausedeviationstoGPSshortwaveaffect
signals.ButweatherfactorswillnotaffectthenormalfunctionofGPS.

6. Whycannotitmonitor?
CheckthememoryforSMSmessagesintheSIMcard,toseeifitisfullornot.
CannotreceiveGSMsignalintheplacewhereyoulocate.
