Abstract
A satellite communication system that combines the benefits of Geosynchronous Equatorial Orbit (GEO) and Non-geostationary (NGSO) satellite systems into a GEO-NGSO hybrid satellite system. The hybrid system allows for various uses, such as, a NGSO-GEO-NGSO handoff, a GEO-NGSO-GEO handoff, and/or a multi-transport operation utilizing both the GEO and NGSO satellites. Based on the path delay differences of the GEO and NGSO satellites, the system may create a data buffer to ensure no data loss.
Claims20
A system for uninterrupted communications in a hybrid satellite network, comprising:
- a multipath manager having a processor;
- a memory that stores instructions that are executed by the processor to:
- communicate, from a server device, with a first gateway and a first satellite, wherein the first satellite is a non-geostationary (NGSO) type satellite or a geosynchronous equatorial orbit (GEO) type satellite, the first server device being associated with a hybrid satellite communication system that includes both NGSO and GEO type satellites, the first server device coordinating handoffs between NGSO type satellites and GEO type satellites of the hybrid satellite system;
- receive, from the first gateway, a handoff request, wherein the handoff request comprises information associated with a second satellite, wherein the second satellite is a NGSO type satellite or a GEO type satellite, and wherein the first satellite and second satellite are different types;
- buffer, based on the information associated with the second satellite, the communications with the first gateway and the first satellite;
- and
- execute the handoff from the first satellite to the second satellite.
A customer premise equipment configured for uninterrupted communications in a hybrid satellite network, comprising:
- a multipath manager having a processor, the multipath manager facilitating communications with a hybrid satellite communication system that includes both non-geostationary (NGSO) type satellites and geosynchronous equatorial orbit (GEO) type satellites, and wherein the hybrid satellite system facilitates handoffs between NGSO type satellites and GEO type satellites of the hybrid satellite system;
- at least one fix-pointing antenna and at least one tracking antenna;
- and
- a memory that stores instructions that are executed by the processor to:
- communicate, from a client-side device, with a first terminal and a first satellite, wherein the first satellite is a non-geostationary (NGSO) type satellite or a geosynchronous equatorial orbit (GEO) type satellite;
- receive, from the first terminal, a handoff request, wherein the handoff request comprises information associated with a second satellite, wherein the second satellite is a NGSO type satellite or a GEO type satellite, and wherein the first satellite and second satellite are different types;
- buffer, based on the information associated with the second satellite, the communications with the first terminal and the first satellite;
- and
- execute the handoff from the first satellite to the second satellite.
