In this report, the design process of a high precision positioning system for Ghana is described. The system consists of two devices, a base station and a user operated rover. These devices provide precision positioning, using dual frequency receivers and the principle of differential positioning. The high precision positioning system can be utilized for multiple purposes. The system can open up business opportunities in surveying, can be used to make height maps for flood prediction and to gather meteorological data. The gathering of weather data is the main purpose of TWIGA, under which flag this project runs.
During this project, the main focus is to create a working product, which can be tested in Ghana as soon a possible. Therefore, the highest priority is to make a functional device in terms of accurate positioning, data connection and power supply. This device should be suitable for the local environmental conditions, such as tropical rain and a high humidity.
