Field mobile positioning device based on backward diode (BD) communication

Abstract

The invention discloses a field mobile positioning device based on backward diode (BD) communication. The device comprises a BD receiving antenna, a signal amplifier, a BD processing board, a power amplifier, a BD transmitting antenna and a data transmission unit, wherein the BD receiving antenna is used for receiving a downlink signal broadcast by a BD satellite; the signal amplifier is connected with the BD receiving antenna and used for denoising and amplifying the signal of the BD satellite, which is received by the BD receiving antenna, and transmitting the denoised and amplified signal to the BD processing board; the BD processing board is used for performing analog-to-digital conversion and processing operation on the signal transmitted by the signal amplifier; the power amplifier is connected with the BD processing board and used for amplifying the signal which is processed by the BD processing board and is to be transmitted; the BD transmitting antenna is connected with the power amplifier and used for transmitting the signal amplified by the power amplifier to the BD satellite; and the data transmission unit is connected with the BD processing board and used for performing interactive data transmission with peripheral equipment. The positioning device is small in volume, light in weight, low in cost and wide in application range.

Description

technical field [0001] The invention relates to a positioning device, in particular to a field mobile positioning device based on BD communication. Background technique [0002] At present, the field communication and positioning equipment based on BD technology application is relatively simple. Since the device needs to transmit signals, it needs a relatively large antenna, and at the same time it needs a large-capacity battery to provide power, resulting in the provided device having a large volume and a heavy weight. In addition, the existing field communication positioning equipment based on the application of BD technology is a self-contained system, which is difficult to integrate with mature professional systems, cannot meet the requirements of field geological surveys, and also makes it difficult to apply to field geological surveys in difficult and dangerous areas. Contents of the invention [0003] The technical problem to be solved by the present invention is t...
