ASM/EDS Engineering Data

(XTE was launched at 0848 EST, Saturday, December 30, 1995)

The ASM/EDS Currents/Voltages/Temperatures as read by the S/C IPSDU
(Typically updated every 128 seconds.)

Note that time has many meanings in a packetized data system. The time displayed for this and the ASM housekeeping below is that placed in the packet on board the Observatory; we have simply converted Mission Elapsed Time to Eastern Standard Time for (our) convenience. The delay shown is the lag between the time this packet was tagged on board the Observatory and the time we received it (not between the time it was collected and the time you might choose to view it). All telemetry is transmitted down via the TDRSS satellite system. There are gaps in coverage, however, so that for 10 minute intervals we are out of contact with the Observatory, and the data you see is the last valid packet received. Under ground command, data collected on board during these telemetry outages is (quickly) dumped some time later in the orbit. Thus you may see relatively old data coming in quickly, overwhelming the current, slow telemetry data.

A detailed description of the current ASM status is also available.

The XTE Science Operations Facility has information on the XTE Observatory operations.

Thess instruments were designed and fabricated by the Laboratory for Space Experiments at the MIT Center for Space Research.
