The YM-250 is capable of fast and accurate positioning in weak signal areas such as cities, canyons, and under elevated viadas, as well as inside the car. It can be widely used in UAV, unmanned vehicle, crossing machine, vehicle monitoring, bus station announcement, vehicle navigation, ship navigation, notebook navigation, driving recorder and other products that need to be positioned.
Functional characteristics
All three kinds of positioning in one, better navigation
GPS+BDS+GALILEO joint positioning, flexible choice, you can choose to use the selection of positioning mode, you can choose single mode positioning, multi-mode combination positioning according to project requirements.
Small size and light weight
Using high performance small volume antenna, miniaturized design, performance does not shrink. Light weight up to 11g, ideal for small traverser/loop machine/light fixed wing use.
Powerful star search performance
T-antenna network design, impedance matching (50Q), antenna standing wave ratio less than 1.5, play the module receiving power advantage, so that the star search performance is strong, accurate positioning.
Get accurate data
Precise position can be obtained by latitude and longitude, and speed and time information can be learned.
