RD120-6W BeiDou RDSS short message communication board is designed on the basis of BeiDou Rf chip and baseband chip independently developed by OLinkStar. It’s mainly composed by high-power amplifier, Rf chip and baseband chip and other parts. BeiDou communication board can meet the needs of the users positioning and communication both on land and sea. Its advantages are: small size, low power consumption and high reliability.
Factories producing BeiDou users’machine for military use and civil use both can bring out competitive BeiDou users’ machine fast based on our board. It can be widely used in satellite navigation, car navigation, marine fishery, UVA and aerological sounding and other fields which are compatible with BeiDou.
