A method for synchronizing wireless network nodes of a wireless communication network involves a base station of the wireless communication network to determine or obtain a maximum value for a frequency content per unit of time of an FMCW radio-frequency signal interfering with the wireless communication network, transmit a first synchronization frame containing a first synchronization sequence in a first wireless communication frequency bandwidth, and transmit a second synchronization frame simultaneously to the first synchronization frame, the second synchronization frame containing a second synchronization sequence in a second wireless communication frequency bandwidth that is spaced apart from the first wireless communication frequency bandwidth by a spectral distance larger or equal to the product of the determined maximum value for the frequency content per unit of time of the FMCW radio-frequency signal and duration of the first and second synchronization sequences.

A task scheduling system that can be used to improve task assignment for multiple satellites, and thereby improve resource allocation in the execution of a task. In some implementations, configuration data for one or more satellites is obtained. Multiple objectives corresponding to a task to be performed using the satellites, and resource parameters associated with executing the task to be performed using the satellites are identified. A score for each objective included in the multiple objectives is computed by the terrestrial scheduler based on the resource parameters and the configuration data for the one or more satellites. The multiple objectives are assigned to one or more of the satellites. Instructions are provided to the one or more satellites that cause the one or more satellites to execute the task according to the assignment of the objectives to the one or more satellites.
