Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 1 As shown, the positioning notification system applied to high dynamic targets with variable attitudes of the present invention includes a transceiver antenna assembly, a low noise amplifier, a power amplifier, a radio frequency module, a baseband processing module, and a battery module.

[0024] The transceiver antenna assembly completes RDSS signal transmission, RDSS signal reception, and RNSS signal reception. The low noise amplifier completes the amplification of the received RDSS signal and RNSS signal. The power amplifier completes the amplification of the transmitted RDSS signal power. The radio frequency module completes the up-conversion of the transmitted RDSS signal to the radio frequency, completes the down-conversion of the received RDSS signal to the intermediate frequency, completes the down-conversion o...

Abstract

The invention provides a positioning and notification system for attitude-varying high-dynamic targets and belongs to the satellite navigation technology application field. The positioning and notification system includes a transceiver antenna assembly, a low-noise amplifier, a power amplifier, a radio frequency module, a baseband processing module, and a battery module; the transceiver antenna assembly completes RDSS signal transmission, RDSS signal receiving, and RNSS signal receiving; the low-noise amplifier completes the amplification of received RDSS signals and RNSS signals; and the baseband processing module, based on an FPGA+DSP architecture, consists of an RNSS processing module and an RDSS processing module, wherein the RNSS processing module and the RDSS processing module applya PMF-DFT acquisition algorithm. The system of the invention is suitable for position monitoring, searching and the like of the attitude-varying high-dynamic targets, integrates an RNSS navigation andpositioning function and an RDSS short message communication function, and is beneficial to the miniaturization design of the system.

Description

technical field [0001] The invention belongs to the application field of satellite navigation technology, and relates to a positioning notification system applied to high dynamic targets with variable attitudes, which is suitable for position monitoring and searching of high dynamic targets with variable attitudes. Background technique [0002] Due to the influence of its motion characteristics, the high dynamic target with variable attitude greatly increases the accuracy of its motion trajectory and the difficulty of recovery. The positioning notification system based on RNSS and RDSS can effectively determine the trajectory of the target by reporting accurate position and speed information in real time. However, due to the high dynamic characteristics of the target: 360° rotation, altitude ≤ 5000km, speed ≤ 7km / s, acceleration ≤ 40g, jerk ≤ 10g / s, etc., the functional requirements for the positioning notification system have been increased. [0003] For the RNSS navigatio...
