Description
Technical field
The invention belongs to the communications field, more particularly to a kind of Big Dipper RDSS short message single-shot devices without receiving channel.
Background technology
Traditional Big Dipper positioning and short message transceiver face equipment costliness, and power consumption is big, the problem of oversized.
This is due to that common Big Dipper RDSS terminals need two frequency ranges of up L frequency ranges and descending S, it is necessary to first receive north
The S frequency ranges and signal of bucket satellite can just launch the signal of L frequency ranges, therefore need the frequency received to penetrate part and baseband portion work always
Make, and need larger baseband processing chip, therefore power consumption is big, antenna size thus cost is also high, it is difficult to integrated to make it
Miniaturization, it is not readily portable in some occasions.
Therefore, it is necessary to improve existing equipment, make the need for it meets function, while the transmission of short message can be provided again
Function.
The content of the invention
It is an object of the invention to solve the defect of above-mentioned prior art and be difficult to the root of popularization to connect there is provided one kind
Receive passage Big Dipper RDSS short message single-shot devices, can by RDSS L frequency ranges send short message, for use in SOS,
Tracking, positioning, management and control, the application of emergency communication.
The present invention is adopted the following technical scheme that：
A kind of Big Dipper RDSS short message single-shot devices without receiving channel, including antenna 1, RF switch 2, transmission channel
Module 3, baseband signal processing module 4.
Antenna 1 is connected with the signal of RF switch 2, RF switch 2 respectively with transmission channel module 3, base band signal process mould
The signal of block 4 is connected, and transmission channel module 3 is connected with the signal of baseband signal processing module 4.
Further, the Big Dipper RDSS short message single-shot devices without receiving channel, with reference to Big Dipper RNSS modules/
GPS module 5, RF switch 2 is connected with Big Dipper RNSS modules/signal of GPS module 5, Big Dipper RNSS modules/GPS module 5 and base band
The signal of signal processing module 4 is connected, and the information of transmission, which then not only includes short message, can also include positional information, temporal information.
Beneficial effects of the present invention：
The present invention need not first receive Big Dipper signal, you can the function of big-dipper satellite RDSS short messages be directly transmitted, because taking
Disappeared commonly required receiving channel, simplifies the structure of device, makes the reduction of present apparatus volume, lower power consumption, stand-by time
Extension, production cost reduction, is particularly suitable for use in SOS, tracking, positioning, management and control, the occasion of emergency communication, with huge
Market value.
