Based on the introduction of the development and application status of BeiDou Navigation Satellite System (BDS) in China, and taking into account of the characteristics and requirements of field construction, operation and maintenance management and data security of geological exploration equipment, this paper proposes the overall conception and technical framework of the BDS application in geological exploration equipment through integration of mobile communication, internet, broadband satellite communication and other technologies. The paper also describes in detail the spectrum planning and the application platform development scheme of BeiDou application terminal products for drilling equipment and geophysical prospecting instruments, which can work as guidance and reference for better application of BDS in geological exploration equipment.
