Quectel releases dual-frequency high-precision combined navigation and positioning module LC29H, enabling multi-industry upgrades and development

On June 21, Quectel's new dual-band, multi-constellation, high-precision GNSS positioning module LC29H was officially launched.The module uses dual-frequency positioning technology, combined with RTK (real-time dynamic carrier phase difference) technology and DR (inertial navigation technology), to meet the high-precision positioning requirements of centimeter and decimeter levels, and help lawn mowers, drones, intelligent Industrial applications such as agricultural machinery and shared two-wheelers realize upgraded experience.

New experience of dual-band multi-satellite precise positioning

The LC29H developed based on Airoha AG3335 chip can simultaneously receive and process GPS, BDS, Galileo, QZSS and GLONAS multi-satellite signals and L1/L5 dual-band signals.The increase in the number of available satellites and the advantages of dual frequency bands allow the terminal equipment equipped with LC29H to speed up the convergence time, achieve fast response, improve positioning accuracy even when the signal is interrupted, and significantly reduce the multipath effect caused by high-rise buildings in the urban canyon environment. influences.

LC29H also integrates 6-axis IMU sensor (3-axis accelerometer + 3-axis gyroscope), loading RTK and DR positioning algorithms, when the satellite signal is partially or completely blocked (such as the vehicle is located in a parking lot, tunnel, urban canyon or forest area, etc.) It can also achieve continuous lane-level accurate positioning in the scene of the area), bringing users an easy-to-use, easy-to-use and accurate navigation experience.When the satellite signal is recovered, the LC29H combines inertial sensor data with GNSS signals, and the integrated navigation can provide fast convergence time and obtain positioning results accurate to the decimeter level.

The combination of a variety of mature positioning technologies makes LC29H synonymous with high-precision positioning modules, which can be widely used in mining trucks, construction machinery vehicles, shared two-wheelers and other application terminals that require relatively high positioning accuracy.

High sensitivity and low power consumption double guarantee more peace of mind

In order to avoid the interference of factors such as excessive external noise during the signal receiving process of the terminal, which affects the accuracy and speed of positioning, the LC29H has a built-in low-noise amplifier (LNA) and a surface acoustic filter (SAW Filter).The combination of the two enables the LC29H to achieve high-sensitivity and high-precision positioning capabilities.At the same time, the LC29H using a 12nm process dual-frequency receiver chip and an advanced low-power management solution can realize low-power GNSS sensing and positioning, and is also suitable for handheld devices, asset tracking, shared vehicles, etc. For industries with high sensitivity requirements, increase the service life of the equipment and reduce the cost input.

In terms of package design, the LC29H ultra-compact LCC package design adopts the classic size of 12.2 mm × 16.0 mm × 2.5 mm. It is compatible with mainstream navigation and positioning modules in the market, and is easy to integrate, helping product developers to quickly apply their ideas to the ground.

Multifunctional and widely used in a variety of models

With the accelerated pace of agricultural modernization in my country, IoT technology also plays an important role in the process of traditional agricultural intelligence.

Agricultural drones equipped with Quectel LC29H (EA) rely on the module to support L1+L5 dual frequency, full galaxy concurrent reception, built-in RTK algorithm, high update rate, high cost performance and other features, enabling fertilization, sowing, cruise monitoring, etc. Working scenarios, to achieve a new generation of agricultural drones with more stable performance, more complete functions, and easier use, helping customers improve their industry competitiveness.

In another field of smart agriculture, agricultural machinery uses the LC29H (BA) high-precision positioning module to give full play to the centimeter-level positioning advantages in precise planting, spraying and harvesting in the agricultural production process, thereby improving agricultural production.yieldand reduce the burden on farmers.

The LC29H (DA) is also redefining lawn mowers with technology.The high-sensitivity and high-precision positioning capability allows users to remotely control and intelligently set the operation line and area of ​​the lawn mower, which makes up for the shortcomings of traditional lawn mowers in terms of manpower, safety and noise pollution, and realizes automatic lawn mowing. , Intelligent operation.

In addition to the field of smart agriculture, LC29H series modules are also widely used in industry, construction and other industries.

The LC29H (BA) used for mining trucks, construction machinery vehicles and other applications can help vehicles in the process of urban road construction. With the help of its RTK, DR and other technologies, it can achieve precise positioning of <20cm, without human real-time tracking, remote positioning and operation. Meet customer needs.

In the field of electric power, the terminal detection equipment can accurately locate the fault area in real time by carrying the high-efficiency LC29H (EA), thereby making the power inspection work more targeted, and effectively improving the work efficiency and safety factor.

After the smart helmet integrated with communication, positioning and other technologies is equipped with LC29H (DA), with the built-in RTK algorithm, the terminal can achieve centimeter-level positioning even in an open environment, satisfying a series of personnel positioning, dangerous rescue, etc. intelligent demand.

A variety of GNSS positioning modules of the LC29H series have been widely used in terminals in the fields of smart agriculture, UAV, and shared two-wheelers. They have obvious advantages in cost, performance, size and power consumption, so they are widely recognized by the mass market.Whether used independently or cross-shared, it brings a new upgrade experience to the industry.

For the GNSS positioning module LC29H, Quectel also provides multi-specification supporting antenna products. The comprehensive IoT solution of "module + antenna" can greatly reduce the difficulty of customer terminal development, improve development efficiency and reduce investment costs.

As the world's leading IoT module manufacturer, Quectel has developed a complete GNSS positioning module product line with its profound technology accumulation and mature service support system.With the continuous development of positioning technology, the launch of LC29H can meet the stringent requirements of various industries for high-precision positioning.In the future, Quectel will continue to increase investment in research and development according to market development and changes, and is committed to leading the faster development of the Internet of Things.
