Works gps satellite signal repeaters Introduction

GPS signal repeaters existing technology to improve the positioning capability of GPS signals, using these new technologies, enables the receiver when the GPS signal is defective work area, can still provide a reliable positioning results.
Mentioned herein satellite navigation signal repeaters are widely used test systems, test equipment used to receive more than one satellite to facilitate customers to place in the room, while supporting signal repeaters GPS, GLONASS, Compass and Galileo global satellite navigation system of four kinds, as satellite navigation signal test systems address the problem of indoor unable to receive satellite signals.
The main satellite navigation signal repeater receiving antenna by the outdoor CNSS, low loss cable (usually a coaxial cable), GNSS satellite signal repeater, indoor GNSS antenna emission system consisting of four complete most of its working principle is outdoors satellite navigation signals through a satellite transponder signal, after filtering and amplification process, real-time satellite radio signal forwarded to the indoor space to the indoor reception apparatus needs to receive GNSS signals to provide a satellite signal. Its operating principle is as follows:
SYN2308 GNSS satellite signal repeater type mainly by the satellite receiving antenna, low loss RF cable, a repeater hosts three parts.
RF signals amplified and filtered by the receiving antenna, the signal sent to the repeater access host-spreading and demodulation is completed, to achieve targeting to check navigation signals, while the code stream and message information and re-modulate and upconvert RF signals obtained through the repeater sent to the RF transmit antenna port of the host.
Main features and technical specifications
gps repeater has two main functions, one of satellite transponder signal enhancement, the second is positioning itself to check. Repeater receives BD / GPS navigation signals, demodulated stream and message information and re-modulate and upconvert obtained RF signal to complete the forwarding function, the output signal level may be adjusted according to actual needs.
Reincarnation of satellite navigation signals in use, outdoor satellite antenna needs to be placed outdoors, it is recommended to set up in the roof of the open space, help can receive satellite signals effectively in any environment, bad weather prevented the satellite signal receiving star interference. At the same time prevent interference thunderstorm, optionally between the satellite antenna and the satellite navigation signals reincarnation Plus BNC type antenna feeder surge protector, which is essential for the construction of a radio base station outdoor preventive surge protector member, laughing can ensure reliable operation of the entire system, making it against lightning induced over-voltage attack, electrostatic discharge and other surge voltage.
Reincarnation of satellite navigation signals in indoor workplaces, through effective satellite radio transmission, the indoor environment to provide a complete test environment. There are many devices on satellite navigation signal repeater, based mainly in the chassis, cabinet, or be equipped with specialized environments on the market in industrial or commercial test system, often only need to meet the requirements of coverage, the system facilitates install, easy to carry and so on.
