1. A method for monitoring a system comprising:
- monitoring the system in real time for a triggering event;
logging data about the system to a first memory upon detection of the triggering event and for a set time after the triggering event occurs;
continuing the monitoring of the system and the logging of data until the first memory is filled; and
sending the data from the first memory to an interface for retrieval.

Abstract
A method for monitoring a system operating in real-time includes monitoring the system for a triggering event or events, recording data about the system to a first memory in real time prior to and/or for a set time subsequent to when the triggering event occurs, and sending the stored data from the first memory to a second memory or an interface for retrieval.

9. An event monitor for a system comprising:
-
one or more sensors operable to monitor one or more parameters of the system; a first memory for storing the data the first memory configured to store data from a first parameter at a first data rate and store data from a second parameter at a second data rate different from the first data rate; and a processor, coupled to the one or more sensors, the processor operable to receive data from the one or more sensor and initiate storage of the received data in the first memory upon the occurrence of a predefined event, the processor further operable to continue the store data upon the occurrence of additional predefined events until the first memory is filled. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A momentum controls system for a spacecraft comprising:
-
an attitude control system configured to adjust the attitude of the spacecraft; an attitude adjustment device; and a monitoring system coupled to the attitude control system, the monitoring system comprising; one or more sensors operable to monitor one or more parameters of the attitude control system; a processor, coupled to the one or more sensors, the processor operable to execute an event log recorder, the event log recorder configured to be placed in an armed state to monitor for a triggering event and a triggered state upon the detection of the triggering event detected by the one or more sensors; and an event log buffer coupled to the processor, the event log buffer configured to store data upon detection of the triggering event and for a set amount of time before the triggering event if the monitoring system is in a first setting and the event log buffer configured to store data upon detection of the triggering event and for a set amount of time after the triggering event if the monitoring system is in a second setting. - View Dependent Claims (20, 21, 22, 23, 24)
