Problems solved by technology

[0005] 1. In the existing technology, by adding a power divider, the RF power from the antenna is divided into multiple signals on average, and provided to the star cards in multiple base station equipment, so that multiple base station equipment can share a set of antenna feeder system, but each The base station equipment still needs an independent star card, which cannot achieve the complete sharing of GPS / GLONASS resources (including antenna feeder system and star card), so the cost cannot be greatly reduced
[0006] 2. The existing technology uses a power divider for radio frequency devices, which reduces the sensitivity of the radio frequency and affects the sensitivity of the signal received by the star card

Abstract

The invention discloses a method of sharing star card resources, which comprises the following steps: the data signals and clock source signals are received; the received data signals and clock source signals are sent to at least two communication devices. The invention also provides a device and network system for sharing star card resources. The invention has the advantages that: the star card resources can be shared by a plurality of communication devices; the cost of GPS / GLONASS user systems is reduced.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a method and equipment for sharing star card resources, base station equipment and a network system. Background technique [0002] At present, wireless communication devices that need synchronization or positioning information, such as 3G or 4G mobile communication devices, basically need to insert star cards to connect satellite antennas to provide time and location information for devices, such as on base station devices A star card needs to be inserted to receive time, location, etc. signals from the satellite dish. Due to the complexity of the star card's own technology, the current cost is very high. With the addition of antennas, lightning arresters, feeders and other supporting components, a complete Global Positioning System (Global Position System, GPS) / Global Navigation Satellite System (Global Navigation Satellite System, GLONASS) user components (incl...
