functionaloverview

 

the yx-1010mkdesignedby dragon basingon themt3339is anew generationofgps receiving module. it’sup to 66 acquisitionand 22simultaneouslytrackingchannel,ultra-high sensitive gps receiving module. based on new highlyintegrated mtkchipsand meticulouslyintegration keyparts ofdragon. in the same chip specifications,this producthas fastergpssignals abilityto capture, lowerpowerconsumption, more stronganti-jamming performance and more wide working voltage range.

yx-1010mkmodule designed with industrial requirements, usingstamps package, can adaptto wet high temperature,electromagneticinterference etc. odiouslyworkingenvironment. it is widelyused in monitoring, positioning, mapping, navigation, securityapplications.
