GPS 参考设计是一个评估套件，旨在展示超低功耗 GPS（全球定位系统）接收器的基本功能，并作为参考设计来说明如何快速实现这样的接收器。该参考设计采用 Maxim Integrated 的 MAX2769C L1 波段 GNSS RF 前端 IC (RFIC)，以及 Baseband Technologies Inc. (BTI) 提供的超低功耗 GPS 基带处理固件，该固件在 MAX32632 微控制器单元 (MCU) 上运行。特点 GPS L1 快照接收器 超快定位，最快 0.9 秒内完成 超低功耗 0.5mW 至 1.57mW（更新率为 60 秒） 实时和后处理操作模式 原生 arm cortex-M4 设计 用户可选择的信号捕获 4ms、6ms、8ms、10ms、16ms、22ms、30ms 定位精度：5m CEP 无源和有源天线支持 SD 卡支持通过 USB 连接 PC 应用 可穿戴设备 物联网 (IoT) 资产追踪 活动追踪 牛群追踪 宠物追踪 儿童追踪 野生动物追踪
The GPS reference design is an evaluation kit designed to demonstrate the essential features of an ultra-low power GPS (global positioning system) receiver, as well as serving as a reference design to illustrate how to implement such a receiver rapidly. The reference design uses the MAX2769C L1-band GNSS RF front end IC (RFIC) from Maxim Integrated, and the ultra-low power GPS baseband processing firmware provided by Baseband Technologies Inc. (BTI) that runs on a MAX32632 microcontroller unit (MCU).
