This paper proposes a smartphone-based network real-time kinematic (RTK) positioning and gravity-surveying application (app) that allows semi-real-time measurements using the built-in Bluetooth features of the smartphone and a third-generation or long-term evolution wireless device. The app was implemented on a single smartphone by integrating a global navigation satellite system (GNSS) controller, a laptop, and a field-note writing tool. The observation devices (i.e., a GNSS receiver and relative gravimeter) functioned independently of this system. The app included a gravity module, which converted the measured relative gravity reading into an absolute gravity value according to tides; meter height; instrument drift correction; and network adjustments. The semi-real-time features of this app allowed data to be shared easily with other researchers. Moreover, the proposed smartphone-based gravity-survey app was easily adaptable to various locations and rough terrain due to its compact size.
本文提出了一种基于智能手机的网络实时动态（RTK）定位和重力测量应用程序（app），该程序允许使用智能手机的内置蓝牙功能和第三代或长期演进无线设备进行半实时测量。该应用程序通过集成全球导航卫星系统（GNSS）控制器、笔记本电脑和现场记录工具，在单个智能手机上实现。观测设备（即 GNSS 接收器和相对重力仪）独立于该系统运行。该应用程序包括一个重力模块，根据潮汐、米高、仪器漂移校正和网络调整，将测量的相对重力读数转换为绝对重力值。该应用程序的半实时功能允许轻松与其他研究人员共享数据。此外，由于其紧凑的尺寸，基于智能手机的重力测量应用程序易于适应各种位置和恶劣地形。
