"IMU/GNSS Convergence BeiDou Terminal Dynamic Detection System" Passed Acceptance

Posted on

[China Instrument Network Instrument R&D] Recently, the Acceptance Meeting for the “IMU/GNSS (Inertial Navigation) Fusion Beidou Terminal Dynamic Detection System” project hosted by the Metrology Institute of Nanjing, Jiangsu Province was held. Nanjing Metrology Institute, Nanjing University of Technology, and Hohai University The expert group consisting of 5 people including Southeast University, after reviewing the acceptance data, hearing the project report, fully discussing and deliberating, agreed that the project passed acceptance.

In 2014, Nanjing Metrology Institute took the lead in the development of the first-generation on-vehicle precision satellite navigation dynamic detection system. It began upgrading the system in 2016, and innovatively combines GNSS and inertial navigation (INS) equipment. Combining this, a BeiDou terminal dynamic detection system that combines satellite navigation and inertial navigation has been developed.
The system is a working platform integrating detection reference system, GNSS signal transfer system, computer system, communication system and on-vehicle power supply system. It has constructed a set of high-precision dynamic detection standards for fusion of satellite navigation and inertial navigation, breaking the complex environment. The challenge of constructing a high-accuracy dynamic positioning verification benchmark represented by RTK (millimeter-level) changed the unfavorable situation of RTK (millimeter-level) dynamic positioning equipment detection in the “external baseline field” and “static” generation “movement”. It is helpful to reflect the functional indicators of the actual application of the satellite navigation and positioning terminal to be inspected. The project will promote the development of standards related to the dynamic positioning detection of Beidou Terminal and provide basis for the development of the business and the development of the industry.

Plastic Injection Clear Housing

Transparency & clear plastic housing

The transparency of the plastic injection transparent shell matrix resin itself has a great influence on the transparency of PP plastic products. In order to improve PP transparency, a small amount of polyacrylate resin with good transparency and compatibility can be added.


(1) the inorganic nucleating agent mainly consists of ultra-fine talc powder and SiO2, and also includes calcium carbonate, mica powder, inorganic pigments and fillers, etc., which is cheap in price and rich in source, but has certain influence on the gloss and transparency of the products.

(2) organic nucleating agent organic nucleating agent is a kind of organics with low relative molecular weight, represented by sorbitol and its derivatives. It has good compatibility with matrix resin and can significantly improve product transparency and surface gloss.

(3) in the case of sorbitol, when the amount of nucleating agent exceeds 0.3%, the effect of transparency improvement is not obvious, and even decreases. However, when the dosage is less than 0.2%, the nucleation quantity is insufficient and the transparency is not increased enough. It can be seen that the amount of nucleating agent should be between 0.2-0.3%. Therefore, suitable nucleating agent content can better improve the transparency of PP.
