随着全球导航和定位系统(GNSS)的不断发展和完善，其应用范围也不断拓宽，广泛应用在航海、航天，个人定位服务等方面。本文基于GPS定位系统结合短距离通信技术将定位数据传输到ONENET云平台，最后将数据传输到用户端进行位置显示，可以实现对走失老人儿童的定位，为被困与迷途人员搜救与寻找提供便利，对野外搜救有着极为重要的意义。
The Global Navigation and Positioning System (GNSS) has been continuously developed and improved, and its application range has been continuously expanded. It is widely used in navigation, aerospace, and personal positioning services. Based on the GPS positioning system and short-distance communication technology, it has been discussed that the positioning data were transmitted to the ONENET cloud platform in this paper, and the data are transmitted to the user for location display. That can achieve the positioning of lost elderly and children, and provide convenience for the search and rescue of trapped and lost people. It is of great significance to search and rescue in the wild.
