Beidou RDSS short message emitting device without receiving channel

Abstract

The invention belongs to the technical field of communication, and discloses a Beidou RDSS short message emitting device without a receiving channel. The device comprises an antenna (1), a radio-frequency switch (2), an emitting channel module (3) and a baseband signal processing module (4); the antenna (1) is in signal connection with the radio-frequency switch (2); the radio-frequency switch (2)is in signal connection with the emitting channel module (3) and the baseband signal processing module (4); and the emitting channel module (3) is in signal connection with the baseband signal processing module (4). The device has a function of directly emitting a Beidou satellite RDSS short message without receiving a Beidou signal, so that the device is simple in structure, small in size, low in power consumption, long in standby time and low in production cost; if the device is combined with a Beidou RNSS module / a GPS module (5), the device is suitable for emergency rescue, tracking, positioning, management and control, and emergency communication; and therefore, the device has a certain market potential.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a Beidou RDSS short-message single-send device that does not need a receiving channel. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] The traditional Beidou terminal with positioning and short message sending and receiving functions is not only large in size, but also expensive in equipment and consumes a lot of power. This is because the usual Beidou RDSS terminal needs two uplink L frequency bands and downlink S frequency bands. It needs to receive the S frequency band and signal of the Beidou satellite before it can transmit the L frequency band signal. Therefore, the radio frequency part and the baseband part that needs to be received are always working. Moreover, a large-scale baseband processing chip is required, so the power consumption is large, the antenna size and cost are als...
