Systems and methods for reliable content delivery from a satellite to sub-edge devices are described. Content is delivered to a plurality of edge devices. Missing portions of the content are identified. One or more of the missing portions are selected, and the selected portions are recovered via a satellite network or a non-satellite network. The recovery is coordinated by a central cloud device based on one or more recovery factors.

Dynamic in-route reconfiguration in a satellite network includes receiving at least one of transmit power capability and demand requirements from one or more active satellite terminals of the satellite network, determining a resulting in-route configuration during operation of the satellite network based on the received at least one of transmit power capability and demand requirements, comparing the determined resulting in-route configuration to a current in-route configuration. When the determined resulting in-route configuration is different from the current in-route configuration, establishing the determined resulting in-route configuration as the current in-route configuration and storing the established current in-route configuration in a dynamic in-route reconfiguration manager, and transmitting the established current in-route configuration to the one or more active satellite terminals.

A system and method are disclosed for synchronizing timing for a terminal in a satellite communication system. Upon detecting a service interruption, first timing markers are extrapolated from timing information received prior to the service interruption. Second timing markers are also extrapolated from timing information received subsequent to the service interruption. Timing for the terminal is then synchronized with the gateway based on a timing difference between the first timing markers and the second timing markers.

An earth station transmitter device is arranged for generating a set of data to be transmitted to an earth station receiver device of a satellite communication system. The earth station transmitter device comprises: encoding and modulation means for mapping a plurality of baseband frames; physical layer framing means arranged for inserting in front of each frame of encoded and modulated symbols; converter means for converting a super-frame preamble; super-frame generator means arranged to prepend a first subset of capacity units corresponding to the super-frame preamble to a second subset of capacity units of the plurality corresponding to the plurality of physical layer frames.

Systems and methods for transmitting data using a satellite communication network are disclosed herein. In an embodiment, a satellite communication network includes a first terminal, a second terminal, and a base station. The first terminal is configured to collect first target data. The second terminal is configured to receive a first data packet including the first target data from the first terminal via a local connection. The base station is in communication with the first terminal and the second terminal via at least one satellite. The base station is configured to: (i) receive copies of the first data packet from each of the first and second terminals via the at least one satellite; (ii) process a first copy of the first data packet; and (iii) delete a second copy of the first data packet.

A method includes receiving a current velocity and a current position of a mobile node relative to a fixed node. The method also includes identifying a receive time slot for the fixed node to receive a transmission of a data packet from the mobile node and determining a propagation delay for the data packet between the mobile node and the fixed node based on the current position of the mobile node. The method includes determining a transmission time based on the receive time slot and the propagation delay and determining a Doppler shift based on the current velocity of the mobile node. The method includes determining a transmission frequency based on the Doppler shift and a clock rate correction. The method also includes transmitting the data packet to the fixed node at the determined transmission time using the determined transmission frequency compensated by the determined clock rate correction.
