It has been rescheduled for Tuesday 7/9/2013 (1300-1400z) due to Santiago having problems with the IIRV file. This test will use a larger uplink power and different modulation index compared to the test on 4/15/2013. The buffer overflow problem (a consistent bias in the range data) from the last test has not been resolved. The MMOC will monitor ACE during the test with telemetry received by WS1. ======================================================================== Anomalies: None
