On March 4, 2022, Beijing United Strong Technology Co., Ltd. *** referred to as "United Strong") held the "2022 Spring New Product Launch Conference" and released two blockbuster new GIS products - MG858A Beidou high-precision intelligent terminal and MG30 Beidou high-precision data collector. These two new products have attracted wide attention in the industry with their core advantages of "high precision, small size, and fixed seconds".
Jisbao is the GIS business brand of Hezhong Strong, the business originated in 1995, has 27 years of development history, with the brand slogan of "crisscrossing the world, brainstorming in the heart", the product line covers meter-level, sub-meter-level, centimeter-level and other precision handhelds, tablets, mobile intelligent terminals and mobile application software and other types, and has launched a number of classic models in history, among which the MG858S product is in. During the period from 2015 to 2018, it has become the sales champion in the domestic sub-meter handheld market for three consecutive years.
The theme of this press conference is "Beyond the Classics, Domestic Products". The MG858A released this time is an upgraded version of the MG858S. MG858A surpasses the classic in positioning accuracy, star search speed, fuselage size, and operating system, and the positioning accuracy of the new product can reach 3 cm, realizing RTK-level handheld positioningL1+L5 dual-frequency positioning is adopted, which has stronger resistance to multipath effect and excellent performance under complex working conditionsThe four-arm spiral antenna takes into account the high-precision phase center while ensuring the satellite signal reception, and realizes a fast fixed solution in 10 seconds. The new product is smaller in size and 75% less in weight than the previous generation, making it easy to operate. In addition, the new product has achieved a huge improvement in battery capacity, storage configuration, and screen size.
As an ultra-thin handheld product, MG858A adopts the latest generation of small-size high-precision positioning module - P54, which is characterized by a small size and low power consumption all-constellation, with a size of only 17*22mm, and the power consumption of the host is as low as 05W, to achieve the whole constellation including Beidou-3 satellite navigation signal reception and high-sensitivity tracking, to ensure stable operation in complex working conditions. In addition, MG858A uses domestic independent SoC processing chips, and the CPU is 8 cores and 20GHz, using the new A75 architecture, 12nm manufacturing process, to achieve a comprehensive balance of low power consumption and energy saving and the ability to handle advanced tasks.
The second new product MG30 Beidou high-precision data collector released in this field can also achieve high-precision positioning within 3 cm, using L1+L5 high-precision positioning module and four-arm spiral antenna, positioning accuracy, star search speed, convergence time and other operation effects are similar to MG858A.
The main difference of MG30 is that it can be used as a wearable device, and can be combined with ordinary precision GIS collectors and even ordinary Android mobile phones through Bluetooth to achieve centimeter-level positioning operations.
MG30 has a variety of operation modes, can be used as a wearable device, can also be used in the center rod mode, because the product has better anti-blocking performance, for the corner, tree and other areas of serious occlusion can also be quickly initialized, to achieve the initialization ability and measurement accuracy comparable to the measurement RTK, can be applied to GIS collection, personnel positioning, patrol inspection, health film law enforcement, gas heating, vehicle applications and other industries.
Yang Yunfeng, the keynote speaker of the press conference and the head of the business of Hezhong Strong, said that at present, mankind is in the best era of high-precision GNSS applications, "Tianshi (global satellite navigation multi-system integration), geographical advantage (Beidou ground-based augmentation system covering the whole country), and people (a variety of high-precision receivers)" are available.
