Goldstone, GBT, and Arecibo Radar Observations Planning for the Galilean satellites in early 2016
This is a planning page for radar observations of the Galilean satelites. Our objective is to use radar ranging measurements of the Galilean satellites in order to detect orbital changes due to their tidal interaction with Jupiter. Our tracks are scheduled earlier than the opposition of Jupiter (Mar 8, 2016) in order to accomodate Goldstone shutdown from January 25 to early May and possible Arecibo shutdown starting in mid-February. We have eight tracks scheduled at Goldstone and GBT. We have currently eight tracks scheduled at Arecibo, but we hope to schedule a few more. Jupiter is a strong radio source, so we have scheduled times when the satellites will be at their maximum angular separation from the planet, a geometry that minimizes Jovian noise.
Physical properties of the Galilean satellites and their respective X- and S- Doppler bandwidths. The SNRs are calculated based on the physical characteristics of the Galilean satellites. Assumed Goldstone Ptx=440 kW and Tsys=18K. Assumed Arecibo Ptx=900 kW and Tsys=23 K. Bistatic tracks with DSS-14 transmitting and Green Bank Telescope (GBT) receiving will increase the SNRs by 2-fold with respect to monostatic DSS-14 runs. These SNRs are valid for mid-to-late January 2016 Diameter Rotation Period Radar Albedo X-band BW S-band BW SNRs (DSS-14) SNRs (GBT) SNRs (Arecibo) [km] [h] [Hz] [Hz] (per run) (per run) (per run) Io 3643.0 42.46 0.20 (OC) 8580 2380 <10 <10 100 Europa 3121.0 85.25 1.50 (SC) 3660 1020 40 80 800 Ganymede 5268.0 171.71 0.84 (SC) 3070 852 65 130 1500 Callisto 4820.0 400.54 0.36 (SC) 1200 334 40 80 800 Last update: 2015 Jan 06
