Ongoing and future instrument upgrades at Gemini

Gemini Observatory is committed to providing its community with the best possible competitive instrumentation suite given technological and budget constraints. The Observatory operates 4 facility instruments plus 1 AO system at each 8m telescope. It is incorporating a new facility high resolution spectrograph, building a major workhorse multi-channel instrument for transient sources follow up, and designing a new multi-conjugate AO system. We also run three major upgrades of workhorse instruments and a long-term program to support user motivated upgrades. This paper provides a summary of results of the last three years of the instrument upgrades program and an update on our strategy to keep our instrumentation suite competitive.
