GHOST is a newly operational optical fiber-fed high-resolution spectrograph at the Gemini South 8.1m telescope.It currently offers the choice of two resolution modes captured by one (or two) input IFUs with a FOV of 1.2” and a spectral resolving power of 56,000 and 76,000 for the unbinned CCDs.At the high-resolution mode, one can also instigate a simultaneous ThXe calibration lamp, which along with a simultaneous pseudo-slit profile constructed from reformatting the input IFU image will allow for precision radial velocity measurements.Here we talk about the proposed roadmap towards full queue operations, potential upgrades, and the error terms contributing to the final on-sky RV precision, which is estimated to be in the 1-10 m s−1 range.
