The disclosure relates to methods for a communication between a sensor and a satellite, and sensors for carrying out such a method. The sensor has a transmission unit for transmitting sensor data from the sensor to the satellite and a computing unit for calculating the position of the satellite at a specified point in time. The satellite is configured to receive and forward the sensor data. The method includes calculating a coverage duration using path parameters of the satellite and the position of the sensor, activating the transmission unit of the sensor during a transmission duration based on the calculated coverage duration, and transmitting the sensor data from the sensor to the satellite during the transmission duration.
