Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

As the world's leading provider of wireless communication modules and solutions, Meige officially launched the new GNSS single-frequency positioning module SGM308 to the industry. This product has high performance, low power consumption, compact size, advanced AGNSS technology EASY, support Beidou3 B1C frequency and other features can be widely used in application scenarios with extremely high positioning requirements, such as asset tracking, sharing economy, personal and pet positioning, and industrial and consumer fields, enabling refined management of the industry and helping digital transformation and upgrading , to provide power for the intelligent connection of all things.

Meige Smart SGM308 is a single frequency positioning module, which can support GPS, BeiDou, GLONASS, Galileo, QZSS satellite signals at the same time (QZSS is a GPS amplification system, the satellite numbers are 33, 34, 35, 36), in the actual measurement application It can search 2-3 more GPS available satellite signals than other products; at the same time, the module supports the multi-system joint positioning configuration mode of GPS+BeiDou, GPS+GLONASS and GPS+Galileo, and supports multi-satellite search at the same time. , Compared with a single GPS system, multiple GNSS systems can increase the number of visible satellites, reduce the first positioning time, and improve positioning accuracy.

The SGM308 module adopts the built-in Flash design of the chip, which is easy to upgrade the firmware program to solve the problems encountered in the application and obtain the best performance. In addition, Flash can save satellite ephemeris information, the chip can quickly locate after power off and restart within 4 hours, and can locate within 10 seconds under normal satellite signal coverage.

Utilizing advanced EASY (Embedded Assistive System) technology, Meage Smart SGM308 module can automatically calculate and predict orbit information for up to 3 days using ephemeris data stored in internal RAM. Therefore, even in the case of weak signal, SGM308 can quickly obtain positioning information; using GLP technology, MeiG Smart SGM308 can adaptively adjust the switching time according to the environment and actual conditions, to achieve a balance between positioning accuracy and power consumption.

In addition, Meige Smart SGM308 first positioning cold start time <25S, hot start time <2S, and the positioning accuracy can be achieved within 2 meters, its sensitivity in tracking mode is -166dBM, recapture -158dBM, cold start -147dBM.

Secondly, SGM308 also integrates LNA (Low Noise Amplifier) and SAW filter (Surface Acoustic Wave Filter) to deal with signal capture in complex environments and ensure device sensitivity, allowing users to have a good positioning and navigation service experience: SAW filter can play a good role in suppressing all kinds of signal interference of equipment; LNA can greatly improve the sensitivity performance of base station receiver.

In terms of package design, MeiG Smart SGM308 module adopts "small and powerful" LCC package with a size of 10.1X9.7X2.4mm, which is compatible with mainstream package designs in the market. On the one hand, it allows customers to easily embed it in various applications. On the other hand, it is especially suitable for logistics tracking, asset management, vehicle after-installation, personnel and pet positioning, and industrial and other scenarios with refined positioning requirements.

At the same time, SGM308 can help record the speed, location and other information of vehicles in the process of logistics and transportation through high-precision positioning capabilities, so as to realize the transparent management of logistics information, help the logistics and transportation industry to better integrate the logistics and transportation chain, and optimize industrial efficiency. . For the people and pet tracking market, SGM308 can also achieve good positioning capabilities, empower smart wearable devices, and "supervise" the whereabouts of people and pets anytime, anywhere.
