GPSPositioning


TheaircraftusesaGPS/GLONASSdualsatellitepositioningsystem.Thesatellitepositioningsystemis
GPSbased,withGLONASSactingasasupplementarysystem.
Duringoutdoorflight,theaircraftusesGPSpositioningwhenithasfoundaGPSsatellitenumber
largerthan7.
OpticFlowandUltrasonicWavePositioning


Theaircraftwillusetheopticflowandultrasonicwavepositioningduringindoor
flight.IftheGPSsignalispoorduringoutdoorflight(ifthesatellitenumber
foundissmallerthan6),thentheaircraftwillautomaticallyswitchtoopticflow
andultrasonicwavepositioning.

Theopticflowandultrasonicwavepositioningsystemcombinesmotionanalysis
tohorizontallypositiontheaircraftduringflightandanultrasonicdistance
measurertodeterminethedistancefromtheground.Itpositionstheaircraft
duringindoorflightandassiststheGPSpositioningsystemduringoutdoorflight.

Theopticflowandultrasonicwavepositioningmoduleislocatedonthebaseof
theaircraft.Itconsistsofanopticalflowcameraandanultrasonicwavesensor.
UsageConditionsandRestrictions

Theopticflowandultrasonicwavepositioningsystemisusedforindoorflight.Itisalsousedforoutdoorflightif
theGPSsignalisweak.Theoperatingheightrangeforthispositioningsystemis0.5‐3m.

Whenusingthispositioningsystem,aftertheaircrafthasbegunflyingandascendedto0.5m,itwilldetermineif
therequirementsforusingthissystemhavebeenmet.Iftheyhavenot,itwillinitiatelanding.Iftherequirements
arenotmetforthissystemduringflight,theaircraftwillalsoinitiatelanding.

Requirementsfortheopticflowandultrasonicwavepositioningsystem:Whenusingthissystem,thearea
underneaththeaircraftneedsbehaveanoticeabletexturedsurface.Userscanputasquareclothontheground,
tableoroveranylarge,flatsurfacetoprovidetherequiredtexturedsurface.
