Description

technical field [0001] The shark fin integrated combined antenna of the present invention relates to an integrated V2X and high-precision navigation external shark fin antenna for automobiles. Background technique [0002] Provide cloud-integrated satellite navigation system (GNSS) solutions for Internet car customers. Provide consumers with high-precision lane-level navigation experience, and use GNSS combined positioning to solve the problem that vehicle-mounted positioning equipment can effectively improve the navigation accuracy in complex driving environments, and can still guarantee reception under unfavorable conditions such as unfavorable multipath interference. The integrity of the satellite signal, combined with the C-V2X function, can solve the multiple accident rate caused by the developed traffic and the large traffic flow, and improve the comprehensive positioning ability of the terminal. Provide real-time high-precision location solution services covering the...
