In recent years, outdoor activities such as hiking, cycling, and fieldwork have placed higher demands on portable track recorders. However, most existing track recorders suffer from two main issues:
- Poor Positioning in Challenging Environments: Many consumer-grade track recorders struggle with accurate and stable positioning in complex environments—such as during rapid movement, or under weak GNSS signal conditions (dense forests, urban canyons, tunnels, etc.). This can lead to lost tracks, large offsets, or incomplete trace logs.
- Limited Endurance: High power consumption and insufficient optimization often result in short battery life, making it difficult for devices to support long-term, continuous outdoor use.
To address these challenges, we developed the ESP32TrackRecorder.
ESP32TrackRecorder is an open-source, high-performance track logger built with the ESP32 microcontroller and the Ublox M9N GNSS chip. It aims to provide reliable, high-accuracy, and long-endurance track recording, even in challenging signal environments or during high-speed movement.
-
Advanced Hardware Design:
- ESP32 as Main Controller: Offers powerful processing, low power operation, Wi-Fi/Bluetooth connectivity, and flexible peripheral support.
- Ublox M9N GNSS Module: One of the most advanced consumer GNSS chips, supporting concurrent multi-band, multi-system (GPS, Galileo, Glonass, BeiDou) positioning. This significantly improves fix speed, signal robustness, and accuracy—especially under weak or complex signal conditions compared to traditional single-system modules.

近年来，徒步、骑行、野外等户外活动对便携轨迹记录仪提出了更高要求。然而，现有的轨迹记录器普遍存在以下问题：
- 复杂环境下定位能力有限：许多消费级轨迹记录器在复杂环境下（如快速移动、弱信号、丛林、城市峡谷、隧道等）难以实现准确、稳定的定位，导致轨迹丢失、偏移大或记录不全。
- 续航能力较弱：功耗高、系统未优化，导致难以长时间持续户外使用。
为了解决这些痛点，我们设计了 ESP32TrackRecorder 项目。
