Secondary payload interface
First Claim
1. A secondary payload interface for secondary payload communications using a primary payload communications channel for a primary payload of a communications satellite configured to communicate data to and from a ground location, the secondary payload interface comprising:
- a plurality of input/output couplers for connecting the secondary payload to the primary payload communications channel for the primary payload of the communications satellite;
wherein the primary payload of the communications satellite performs a first service associated with the communications satellite, and communicates data for the first service from the primary payload to a first ground station using the primary payload communications channel, and wherein the secondary payload provides a second service, the second service different from the first service;
circuitry for allowing the secondary payload to communicate with the ground station or a second ground station using the primary payload communications channel; and
wherein the plurality of input/output couplers allow some or all of the primary payload communications channel to be restored to the primary payload when the secondary payload is not communicating with the ground station.

Abstract
A secondary payload interface for payload communications using a primary payload communications channel is provided. The secondary payload interface may include a plurality of input/output couplers which may connect the primary payload communications channel to a secondary payload. The plurality of input/output couplers may establish an isolated secondary payload communications channel within the primary payload communications channel. The secondary payload interface may be designed such that control and telemetry interactions with the operators of the communications satellite are limited.

34. A method for controlling at least one secondary payload hosted on a communications satellite configured to communicate data to and from a ground location, the method comprising:
-
isolating a secondary payload communications channel within a primary payload communications channel for a primary payload on the communications satellite using a secondary payload interface, wherein the secondary payload interface comprises a plurality of directional couplers that isolate the secondary payload communications channel, and wherein the primary payload on the communications satellite performs a first service associated with the communications satellite, and communicates data for the first service from the primary payload to a first ground station using the primary payload communications channel, and wherein the secondary payload provides a second service, the second service different from the first service; securely controlling the at least one secondary payload via the isolated secondary payload communications channel; and allowing some or all of the primary payload communications channel to be restored to the primary payload when the secondary payload is not communicating with the ground station. - View Dependent Claims (35, 36)
