Embodiment Construction

[0021] Hereinafter, one embodiment of the present invention will be described based on the drawings.

[0022] Figure 1 to Figure 6 , is a block diagram showing the functional structure of the Beidou and Tiantong satellite-based communication and positioning integrated terminal 1 involved in an embodiment of the present invention, including a data processing module 2, a Tiantong module 3, a Beidou RDSS module 4, and a Beidou RNSS module 5. Tiantong Beidou quad-band antenna6.

[0023] In the integrated terminal 1, the Tiantong signal, the Beidou RDSS signal and the RNSS signal received by the Tiantong Beidou four-frequency antenna 6 are respectively transmitted to the Tiantong module 3, the Beidou RDSS module 4 and the Beidou RNSS module 5 through the radio frequency coaxial cable, Each module integrates the radio frequency channel and baseband signal processor. After each module is processed, the standard interface protocol data is output to the data processing module 2 throu...

Abstract

The invention discloses a communication and positioning integrated terminal based on Beidou and Tongtong satellites. The communication and positioning integrated terminal is characterized by comprising a data processing module (2), a Tongtong module (3), a Beidou RDSS module (4), a Beidou RNSS module (5) and a Tongtong Beidou four-frequency antenna (6) which are arranged in a Beidou and Tongtong satellite two-in-one terminal (1). The two-in-one terminal of the Beidou and the Tiantong satellite has positioning and short message communication capabilities of a Beidou system; The system also hasthe short message and data communication capability of the Tiantong No.1 satellite, can automatically select an optimal sending mode according to the data size sent by a user and the satellite signalstate, and can provide reliable data transmission and positioning functions for the user.
