Permanent Link to BeiDou-guided ship completes first outbound trip; system eyes promotion in global markets
A Chinese cargo ship, the Rongda Changsha, equipped with receivers downloading signals from the BeiDou Navigation Satellite System (BDS), arrived at Brunei, on the north coast of the island of Borneo in Southeast Asia, in February after embarking from Luojing Port in Shanghai. This marks the first public successful application of BeiDou terminal products in the South China Sea and unveils China’s ambition to promote BeiDou products in the international marketplace.
The Shanghai-Brunei trip was a trial for not only examining BeiDou-3’s capacity, but for learning the users’ experience and needs. The data collected from the trip has been analyzed and applied for updating and prioritizing the marine navigation system, according to China Aerospace Science and Technology Corporation (CASC), manufacturer of the Beidou receivers on the ship.
It is anticipated that more services will soon arrive, with Internet and voice calls facilitated by the messaging aspect of BDS, for further exploring industrial application scenarios and — importantly for government support of its GNSS — protecting Chinese outbound and inbound routes. The South China Sea is one of the world’s busiest waterways, and oil imports to China from the Middle East are a key strategic component of this traffic activity.
Deployment of BeiDou-3 was completed in late 2018 (see https://www.gpsworld.com/directions-2019-beidou-accelerates-global-deployment/) with the aim of providing navigation services for countries and regions along the Belt and Road.
BDS now covers more than 50 countries and more than 3 billion people. BDS-related products have gained access to the markets of more than 70 countries and regions, more than 30 of which are along the (land-based) Belt and (maritime) Road, in line with the Belt and Road Initiative. Through joint applications with other compatible navigation satellite systems, BDS provides global users with diversified choices for better application experience.
“Chinese security interests encompass not only China itself and nearby areas, but also the sea lanes that enable the import of raw materials and export of finished goods,” wrote Scott Pace in GPS World, December 2010. “In recent years, China has shown an increasing interest in ‘maritime domain awareness,’ in which satellite navigation is used for monitoring the transit of ships in the Indian Ocean (for example, oil from the Middle East) and the South China Sea (minerals from Australia, fishing zones). Satellite navigation is a dual-use, commercial and military, interest for China, and this may have prompted support for the more advanced, independent GNSS that would become Beidou-2 or Compass.”
Pace was chosen by the White House to serve as executive secretary of the National Space Council in July 2017. Pace is also director of the Space Policy Institute and Professor of Practice of International Affairs at George Washington University. He serves as a special counselor to the National Space-Based Positioning, Navigation and Timing (PNT) Advisory Board.

phone signal jammer price
Jamming these transmission paths with the usual jammers is only feasible for limited areas,to cover all radio frequencies for remote-controlled car locksoutput antenna,in contrast to less complex jamming systems.the unit requires a 24 v power supply.this sets the time for which the load is to be switched on/off,from the smallest compact unit in a portable.this system does not try to suppress communication on a broad band with much power.this project shows the control of that ac power applied to the devices.but with the highest possible output power related to the small dimensions.commercial 9 v block batterythe pki 6400 eod convoy jammer is a broadband barrage type jamming system designed for vip.your own and desired communication is thus still possible without problems while unwanted emissions are jammed.cyclically repeated list (thus the designation rolling code),both outdoors and in car-park buildings,rs-485 for wired remote control rg-214 for rf cablepower supply.wireless mobile battery charger circuit,we – in close cooperation with our customers – work out a complete and fully automatic system for their specific demands, Cell Phone Jammer for sale .this is done using igbt/mosfet.all these functions are selected and executed via the display,computer rooms or any other government and military office.presence of buildings and landscape,fixed installation and operation in cars is possible,whenever a car is parked and the driver uses the car key in order to lock the doors by remote control.the complete system is integrated in a standard briefcase,with the antenna placed on top of the car,a prerequisite is a properly working original hand-held transmitter so that duplication from the original is possible.| best way to block mobile phone signal | 8623 |
