BD/GPS (or GPS/GLONASS) dual-mode navigator is a navigation and positioning device based on navigation and positioning technology, GIS, wireless communication technology, and advanced technologies such as computer software and network. The navigator can display the dynamic position (longitude and latitude), time, status and other information of the carrier on the screen, navigate according to the user's needs, and simultaneously transmit the short message by position or other information through the GPRS wireless communication link. The navigator has the characteristics of accurate navigation and positioning, reliable performance, flexible application and easy operation. In addition, it also has functions such as video playback, music playback, e-books, games, etc.

System composition and workflow
The core positioning chip used in this system is the multi-mode compatible navigation positioning chip OTrach-32 independently developed by Oriental Lianxing Company, which can receive BD, GPS and GLONASS satellite signals at the same time. The high-performance architecture's 32-channel design enables fast signal capture. At the same time, the design of the navigation and positioning algorithm is completed, and it is integrated into the Window CE system by means of a driver. At the same time, the development and integration of electronic maps and navigation algorithms and application software are completed.
The processor uses the S3C2440 chip based on the ARM 920T core structure, with a clock speed of up to 530 MHz, SDRAM of 64 MB, Flash of 32 MB, external SDRAM and NANDFlash. The Window CE5.0 operating system is ported on it.
System composition diagram
The general workflow of the navigator is as follows: First, the navigator obtains the specific geographical location information of the carrier and other ancillary information (such as driving speed and time) through the satellite navigation positioning chip (OTrack-32) and related algorithms. Then, through the map in the built-in storage device, the map portion corresponding to the current location is displayed on the color display screen, and the state of itself (such as speed, time, what kind of message is received, etc.) is displayed. By setting up the GPRS communication module, you can realize the communication connection with the Internet or other terminals.
The dual-mode navigator can use any Windows CE 5.0-based navigation software on the market, such as Kay LiDE, Dao Dao Tong, Gao De and so on. The navigation software is stored in the SD card and does not require special installation. Different navigation software can be used by replacing the SD card.
Features
The dual mode navigator has the following advantages:
â—† BD/GPS (or GPS/GLONASS) dual system navigation and positioning to make positioning more accurate, safe and reliable;
â—† Adopting independent intellectual property positioning chip, hardware circuit and software are all localized, technical support and product upgrade are more secure;
â—† Suitable for a variety of carriers, with excellent dynamic performance;
â—† Powerful, integrated GPRS communication function and a variety of entertainment and leisure functions, using 4.3-inch touch screen, clear display;
â—†Using Windows CE operating system, large-capacity SD card, easy to replace a variety of maps.
in conclusion
After long-term application test, the functions and technical indicators of the navigator meet the design requirements, and have the characteristics of accurate navigation and positioning, reliable performance, flexible application and easy operation. The internal use of BD / GPS / GLONASS multi-mode compatible satellite navigation chip OTrack-32, with the same or better than the foreign navigation chip technical indicators, and has been widely used since 2008. The satellite navigation device using the chip can be applied to vehicles, navigation, aviation, and other places such as personal travel, wild adventure, and the like that require navigation. Its excellent performance will surely show extraordinary quality.
Triconex is both the name of a Schneider Electric brand that supplies products, systems and services for safety, critical control and turbomachinery applications and the name of its hardware devices that utilize its TriStation application software. Triconex products are based on patented Triple modular redundancy (TMR) industrial safety-shutdown technology. Today, Triconex TMR products operate globally in more than 11,500 installations, making Triconex the largest TMR supplier in the world.
Company History: The history of Triconex was published in a book called 'The History of a Safer World' by Gary L. Wilkinson. The company was founded in September, 1983 by Jon Wimer in Santa Ana, California and began operations in March, 1984. The business plan was written by Wimer and Peter Pitsker, an automation industry veteran and Stanford graduate. They presented the plan for a TMR (Triple Modular Redundant) based system that would improve the safety and reliability in industrial applications. Among the customers they targeted were the petro-chemical giants, such as Exxon, Shell, Chevron, and BP.
Pitsker and Wimer presented the business plan to Los Angeles based investor Chuck Cole, who was also a professor at USC. Cole was interested, so he contacted his personal attorney, future two-time Los Angeles Mayor Richard Riordan. Riordan agreed to invest $50,000 and Cole's venture capital team matched it, providing the seed money for Triconex. After two years, however, the company nearly failed due to the expense and complications of testing a new safety system. In February, 1986, founder Wimer left the company and the board asked a seasoned executive, William K. Barkovitz to become CEO. Barkovitz ended up leading the company for 9 years. At the end of his term, Triconex became the leading safety system in a market it largely created, made acquisitions, and completed an IPO. In January, 1994, Triconex was acquired by British based SIEBE for 90 million dollars.
The hardware architect of the Tricon was Gary Hufton, the Software development manager was Glen Alleman. These managers, with Wing Toy (the lead engineering of the fault tolerant ESS telephone switch), led a small successful engineering team that built the first Tricon, sold in June, 1986. Soon after, Exxon became a customer and automation giant Honeywell agreed to distribute the Tricon. Among the software engineers who worked for Triconex were Phil Huber and Dennis Morin, who later left the company to found Wonderware, also based in Irvine California which became the world's leading supplier of Human Machine Interface (HMI).
