Multi-Rover baseline establishment method for GNSS cloud positioning

The invention provides a multi-Rover baseline establishment method for GNSS cloud positioning, and the method comprises the following steps: a terminal is connected to a GNSS calculation server, and uploads observation value data to the GNSS calculation server; the GNSS resolving server runs a resolving program, calculates the real-time coordinate value of the terminal and sends the real-time coordinate value to the AOI server; the AOI server records the coordinate values of all the terminals and updates and calculates the relative positions of all the terminals in real time; the AOI server judges whether the terminal triggers a predefined event or not according to the calculation result, and the GNSS resolving server is informed if so; otherwise, the next epoch resolving is carried out the GNSS resolving server judges whether conditions are triggered or not, if yes, a base line is built for resolving, and then next epoch resolving is carried out; otherwise, the next epoch resolving isdirectly carried out.
