Abstract

The invention discloses a Big Dipper second-generation satellite signal transponder which belongs to a Big Dipper second-generation satellite signal application technology and mainly solves the problem that indoor equipment is difficult to receive Big Dipper second-generation satellite signals in the prior art. The Big Dipper second-generation satellite signal transponder comprises an outdoor signal active receiving antenna used for receiving the Big Dipper second-generation satellite signals, a signal processing device connected with the outdoor signal active receiving antenna through a feeder line and an indoor signal emitting antenna connected with the signal processing device through a feeder line, wherein the signal processing device is internally provided with a power supply device. The invention also provides an implementation method of the device. The invention reduces the production cost of a product while guaranteeing that the Big Dipper second-generation satellite signals are effectively transmitted to terminal equipment in time and improves the overall image of the product.

Description

technical field [0001] The present invention relates to a signal transponder, in particular to an outdoor-indoor transponder for Beidou second-generation satellite signals and its realization method. Background technique [0002] With the construction of the second-generation Beidou navigation system, the application of terminal equipment based on the second-generation Beidou navigation system will also become more and more extensive. Traditional satellite signal application terminal equipment generally receives satellite signals by erecting outdoor antennas. However, this conventional signal receiving method is increasingly unable to meet the needs of the development of modern science and technology. For example, the terminal equipment is set in a remote location, and the signal receiving ability is very weak, and even the signal cannot be received at all. In the process of scientific research, production, testing and debugging, the terminal equipment is installed indoors....
