Analysis of Core Modules and Application Scenarios of Micro Chip for GPS Tracker

In terms of technology, the performance parameters of GPS chips are very important, such as positioning accuracy, sensitivity, cold start and hot start time, power consumption, etc. Different application scenarios may require different performances. For example, vehicle tracking may require high accuracy, while pet tracking may pay more attention to low power consumption.

Core Modules of GPS Trackers:

• Integrated Module + Antenna Design: Integrated ceramic antennas simplify installation and have strong anti-interference capabilities, commonly used in vehicle trackers.
• Built-in Waterproof Housing and Connecting Lines: Suitable for outdoor asset tracking, supporting IP67-level protection.

Communication Module Technologies:

• Cellular Networks: Quectel's series of IOT SIM Cards support 4G/3G/2G or LTE/CAT1 dual-band, combined with GPS to achieve real-time location transmission, suitable for logistics vehicle tracking.
• Low-Power Wide-Area Networks (LPWAN): Adopting multiple working modes to achieve low-power operation, and built-in rechargeable batteries enable long-lasting battery life, which can run for 30 days or even longer, suitable for devices in remote areas (such as agricultural machinery).
• High-Precision Positioning Chips: Using high-end chips to achieve centimeter-level positioning accuracy, suitable for autonomous driving and drones. Specifically designed for the Internet of Things (IoT), with tracking sensitivity of -160dBm. Mainstream chips generally support multi-system joint positioning of GPS + BeiDou + Galileo + GLONASS, enhancing positioning reliability in complex environments.

A-GPS (Assisted GPS): It is a positioning technology that combines traditional GPS satellite positioning with auxiliary data from mobile communication networks, aiming to solve the problems of slow positioning speed, low accuracy, or weak signals of traditional GPS in certain scenarios. In places with weak satellite signals such as indoors, underground parking lots, and between high-rise buildings, A-GPS by obtaining precomputed auxiliary data from positioning servers through mobile communication networks (such as 4G, 5G, Wi-Fi), improving positioning success rate (traditional GPS may fail to position).
