GPS navigation

TheoriginofGPS

Intheearlydays,GPStechnologywaswidelyusedinmilitaryland,sea,andairnavigation,fixed-pointbombing,andguidanceofship-basedmissiles.Especiallyinthe1991GulfWar,theUSmilitary'smissilesaccuratelyhitlong-rangetargetsundertheguidanceofthesatellitepositioningsystem,whichleftadeepimpressionontheworld.Sincethen,GPStechnology,alsoknownassatellitenavigationtechnology,hasattractedpeople'sattention.WiththeopeningofGPStechnologytocivilianuse,thehugebusinessopportunitiesitcontainshavebeentapped.IndevelopedcountriessuchasEuropeandtheUnitedStates,theGPSindustrygeneratestensofbillionsofdollarsinannualbenefits.Especiallywiththeintegrationandminiaturizationofsatellitenavigationreceivers,variouspersonalinformationterminalsintegratingcommunications,computers,andGPShaveemerged.Itisthesatellitenavigationtechnologyfromprofessionalapplicationstothegeneralpublic,becomingthethirdintheinformationindustryaftercommunicationsandtheInternet.Anewgrowthpointandanimportantpartofthecountry’scomprehensivenationalstrength.

Featuresofthesystem

1.Global,all-weatherwork:

Canprovideuserswithcontinuous,real-timethree-dimensionalposition,three-dimensionalspeedandprecisetime.Notaffectedbytheweather.

2.Highpositioningaccuracy:

Singlemachinepositioningaccuracyisbetterthan10meters,usingdifferentialpositioning,theaccuracycanreachcentimeterlevelandmillimeterlevel.

3.Multiplefunctionsandwideapplications:

Withthedeepeningofpeople’sunderstandingofGPS,GPShasnotonlybeenwidelyusedinmeasurement,navigation,speedmeasurement,andtimemeasurement,etc.,Anditsapplicationfieldscontinuetoexpand
