Embodiment Construction

[0021] figure 1 A global positioning system receiver based on a system-on-chip in an embodiment is shown. The receiver includes an antenna 1, a radio frequency chip 2, an integrated chip 3, and a peripheral interface unit 4, wherein:

[0022] Antenna 1 is used to receive radio frequency signals, that is, GPS radio frequency signals of all satellites within the horizon, and a right-handed circularly polarized antenna with hemispherical gain coverage can be used.

[0023] The radio frequency chip 2 is connected to the antenna 1 for converting the received radio frequency signal into a digital signal. The radio frequency chip 2 can be implemented by an existing conventional radio frequency chip, and a low-noise preamplifier can be set inside. The radio frequency signal is amplified by the low noise preamplifier, and the amplified radio frequency signal can be down-converted by the mixing signal from the local oscillator To the intermediate frequency, and then carry out the conversion ...

Abstract

The invention provides an SOC (System On a Chip)-based GPS (Global Positioning System) receiver which comprises an antenna, an RF (Radio-Frequency) chip and an IC (Integrated Chip). The antenna is used for receiving an RF signal, the RF chip is connected with the antenna and used for converting the RF signal into a digital signal, and the IC is connected with the RF chip and used for carrying out baseband processing on the digital signal and carrying out positioning calculation according to a baseband processing result to acquire position information. The SOC-based GPS receiver provided by the invention has decreased making cost.

Description

【Technical Field】 [0001] The present invention relates to satellite positioning technology, and more specifically, to a global positioning system receiver based on a system-on-chip. 【Background technique】 [0002] The navigation application of the Global Positioning System (GPS for short) has gradually become mature. The GPS receiver is used to capture the satellite signals that are tracked, measure the pseudo-distance from the antenna to the satellite and the rate of change of the distance, demodulate data such as satellite orbit parameters, and calculate the user's location information based on these data. System on Chip (“SOC” for short) is also known as a single system chip, which refers to the realization of a complex electronic system on an integrated circuit chip, so it is the core chip integration of an information system. [0003] With the maturity of monolithic microwave integrated circuits, microstrip filters, and surface acoustic wave filters, and the advancement of ci...
