We are doing a receive run - NOW - from Arecibo controlled via laptop from ISEE-3 Mission Control at McMoons in northern California.
Taking data received on 29 May 2014, we have performed demodulation, error correction, and frame construction. Approximately 1,000 frames of telemetry have been received and processed. 773 Frames were received with no errors. More telemetry processing is currently underway.
Using the Arecibo 130 arc second beam width allowed our team to improve the ranging solution over the baseline JPL Horizons (2001 circa) data. Using Arecibo and asteroid-style orbit determination, this resulted in an improved ephemeris. It also reduced the Trajectory Correction Maneuver (TCM) burn from 50-60 m/s to <10 m/s. This reduces post-lunar flyby dV to <10 m/s for ESL-1 insertion.
