1. A method for communication between a sensor and a satellite, wherein the sensor has a transmission unit for transmitting sensor data from the sensor to the satellite and a calculation unit for calculating a position of the satellite at a particular instant, and wherein the satellite is configured to receive and forward the sensor data, the method comprising:
calculating a coverage time period with aid of trajectory parameters of the satellite and a position of the sensor, wherein the coverage time period corresponds to a time period in which the sensor is located in a footprint region of the satellite;
activating the transmission unit of the sensor during a transmission time period based on the calculated coverage time period, wherein the coverage time period or a part of the coverage time period is selected as the transmission time period; and
transmitting the sensor data from the sensor to the satellite during the transmission time period.
