The Hongqi-H9 wide-range satellite, which was launched on January 15, 2020, has a resolution of less than 1 m and a swath width of 136 km. This satellite is the largest sub-meter level satellite worldwide and the first ton-level commercial remote sensing satellite in China. In particular, this satellite can acquire sub-meter image data for an area of approximately 1,000 km2 per second and full-coverage image information for an area of more than 1,000,000 km2. This study was aimed at assessing the geometric positioning accuracy of the Hongqi-H9 satellite considering three aspects, namely, the circle error accuracy, rational polynomial coefficient based direct geometric positioning accuracy and ground control point based absolute positioning accuracy under urban, plain, and mountainous areas, with different topographies. The results of the conducted experimental investigation indicated that the Hongqi-H9 satellite could exhibit a high positioning accuracy in planar and vertical directions for different terrains. In particular, for areas with a low topography and few surface structures, the geometric positioning accuracy of the Hongqi-H9 satellite imagery was less than 4 and 2 m in the planimetry and elevation directions, respectively. These characteristics can promote the application of the Hongqi-H9 satellite images in agricultural surveys, target detection, and land surveys, among other domains.

The Internet of Things (IoT) has developed tremendously over the past few years and has proven its worth in many areas of activity. With regard to environmental air quality monitoring, there are more and more products and applications that try to gather as much data as possible about all the pollution factors in a given area. This paper aims to present a new method of using devices capable of communicating with each other using the LoRa communication protocol to report to a real-time central server on environmental air quality. The innovation of this paper is the fact that it is implemented using a developed LoRa localization protocol, which connects an air quality sensor network, using only the low power of the LoRa technology by applying a multilayer algorithm to the gateway timestamps from received packages. The so created LoRaWAN tracking system is able to exploit transmitted packets to calculate the current position without using GPS or GSM that are high power consumers.
