Quectel Releases GNSS Single-Frequency Positioning Module LC76G, Realizing a New Experience of High-Performance Precise Navigation

Recently, Quectel's all-galaxy single-frequency positioning module LC76G was officially released.LC76G can realize the combination of low power consumption and high performance, ensuring that the vehicle can achieve faster and more accurate positioning even in complex urban canyon environments.The module has now reached mass production, which can well make up for the urgent demand for high-performance single-frequency positioning modules in the current market.

The LC76G developed based on Airoha AG3352 can simultaneously receive and process GPS, GLONASS, BeiDou, Galileo, QZSS satellite signals, and supports SBAS (Satellite Based Augmentation System), with up to 47 tracking channels, making it the number of available satellites It has also been greatly improved, helping the LC76G to improve the positioning accuracy to within 1.5 meters, which is 40% higher than that of the previous generation.

In addition, the hot start time of LC76G is less than 1S, and with the technical support of AGNSS (Auxiliary GNSS Service), the warm start time is controlled within 2S, and the cold start time is controlled within 15s.Quick start, allowing users to enjoy accurate positioning and navigation services anytime, anywhere.The existence of these remarkable characteristics of the LC76G is an important reason why it has become the mainstream choice in the current single-frequency positioning module market.

In order to meet the diverse needs of the market and customers, the LC76G currently has two versions with low power consumption and more cost advantages to choose from.Among them, the power consumption value of the low-power version of the LC76G is less than 9mA @3V, and the power consumption is also reduced by 72% compared with the previous one when four constellations are used at the same time.

The LC76G integrates a surface acoustic wave (SAW) filter and a low noise amplifier (LNA).The SAW filter can prevent the radio frequency interference that the device receives when receiving the signal; and the low noise amplifier (LNA) can reduce the overall noise figure of the receiver and improve the receiving sensitivity.The fusion of this configuration ensures that the vehicle can quickly capture and track signals even in complex urban environments to the greatest extent, and ensures high-precision positioning with the current industry-leading high sensitivity.

At the same time, the built-in EPO (Extended PredictedOrbit) of LC76G helpsterminal equipment to download ephemeris information for up to 14 days in a network environment and reduce its time to first fix (TTFF). Predicts orbital information for up to three days and stores this information into internal RAM.The complementarity of the two technologies ensures that the LC76G can also achieve fast positioning in emergencies.

The many advantages of the LC76G make it cost-effective to use and reach a new height, which is widely recognized by the market.It is currently widely used in industrial and consumer scenarios such as asset tracking, sharing economy, personal and pet positioning, etc.For example, LC76G can help to record the moving speed, driving trajectory, position and other information of the shared two-wheeled vehicle during the moving process.Through the high-precision positioning capability, the management and optimization of "fixed-point retrieval and standardized parking" of vehicles can be realized, and the user's vehicle experience can be improved, helping enterprises to improve work effects and reduce labor costs.In addition, smart wearable devices with high popularity can also use LC76G to help realize their functions: after the elderly and children wear wearable devices equipped with LC76G, relatives and friends can keep track of their movement trajectory, current location and other information through other terminal devices. , to avoid getting lost, lost and other phenomena.

In terms of package design, the LC76G adopts an ultra-compact LCC package design with a size of 10.1mm*9.7mm*2.4mm, which meets the size requirements of mainstream products in the market.At the same time, this module can achieve mutual compatibility with Quectel L76, L76K, L76-LB modules, provide customers with a more efficient and convenient terminal upgrade iterative experience, save time and cost, and achieve earlier product launch and better Competitive.

Quectel also provides a wide range of high-performance antenna products, and the use of supporting modules greatly improves the speed of its wireless connection.The LC76G can be combined with GNSS L1 antennas to meet the high market demand for positioning functions.At the same time, Quectel can provide comprehensive antenna design and testing support according to the individual needs of customers, helping customers to complete product development with high efficiency and low cost.

At present, Quectel has multi-mode, multi-frequency, DR, RTK and other functional product portfolios in the field of positioning modules, which can meet the diverse needs of customers.In the future, with the continuous development of positioning technology, the market has higher and higher requirements for the accuracy, cost and power consumption of positioning products. Quectel will continue to increase technical investment and innovate new scenarios of positioning service ecology.
