Apr 1, 2006 • The Landsat 5 Flight Operations Team (FOT) engineers recently determined that the Mar. 16 Traveling Wave Tube Amplifier (TWTA) anomaly was due to a power spike coinciding with transmitter turn-on. To avoid this crippling power surge, the FOT has implemented an alternate power-on procedure, allowing Landsat 5 data acquisitions and data downlinks to resume.
