Embodiment Construction

[0024] figure 1 It shows the internal structure of the ADS-B portable device 1000 and the connection diagram between the ADS-B portable device 1000 and the external GPS antenna 3000 circuit. The ADS-B portable device 1000 is installed in the aircraft. When it is detected that the external GPS antenna 3000 is connected, the ADS-B portable device 1000 can automatically switch the antenna for receiving GPS signals, and use the external GPS antenna 3000 to receive GPS signals. .

[0025] Such as figure 1 As shown, the ADS-B portable device 1000 includes: an external antenna detection circuit 1100 , an antenna control circuit 1200 , an external antenna power supply circuit 1300 , a built-in antenna power supply circuit 1400 , a built-in antenna signal processing circuit 1500 , and a built-in GPS antenna 1600 .

[0026] The external antenna detection circuit 1100 collects and processes the measurement parameters output from the output terminal of the external antenna power supply ...

Abstract

The invention relates to an ADS-B portable device. The ADS-B portable device is installed in an aircraft, and the ADS-B portable device comprises a built-in GPS antenna, and an external antenna detection circuit and an antenna control circuit which are connected in sequence, wherein the external antenna detection circuit collects and processes measurement parameters, and the measurement parameters are used for judging whether the ADS-B portable device is connected with an external antenna; and according to the measurement parameters, the antenna control circuit controls the ADS-B portable device to receive GPS signals by using the built-in GPS antenna or the external antenna. According to the invention, the ADS-B portable device is capable of automatically switching the antenna to receiving the GPS signals, the cost of the device is saved, and the device is convenient for a user to use; in addition, when the external GPS antenna is used, the external GPS antenna is shielded a little, the receiving of the GPS signals is facilitated, and the stability of the signal emission is improved for the ADS-B portable device.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to an ADS-B portable device. Background technique [0002] In traditional radar systems, many aircraft do not have GPS positioning and navigation functions. During flight training and mission execution, they only rely on tower visual data or voice command commands for positioning, which is less safe. In the ADS-B system, the ADS-B portable device can not only provide accurate monitoring information in real time, but also has obvious advantages such as low construction cost, high data accuracy, and long service life. The aircraft loaded with ADS-B portable equipment has GPS positioning and navigation functions, and can broadcast its own precise position and other data (such as speed, altitude, and whether the aircraft is turning, climbing or descending, etc.) through the data link. [0003] ADS-B portable devices are generally integrated with GPS antennas, and the quality of GPS s...
