Abstract

A Laser Traffic Control System (LTCS) for laser beam avoidance has been in use at the W. M. Keck observatory on Mauna Kea since 2002. Subsequent LTCS installations have occurred at Gemini North (2003), and at the William Herschel Telescope on La Palma, Canary Islands (2005). Gemini North laser tests in 2005 necessitated algorithm changes to provide support for multiple laser configurations. Operational differences for how laser-telescope priority resolutions occur on La Palma vs. Mauna Kea necessitated algorithm changes to address more generic specification of priority rules, collision event queries, and better display feedback. A joint collaboration between the W. M. Keck observatory and the Isaac Newton Group, to install the LTCS at La Palma and enhance its priority processing algorithm and display functions, occurred in 2005. The changes made should be sufficient to support LTCS software implementations at many different sites, current and future, where multiple laser/telescope configurations are planned. This paper will describe the algorithm changes, review outstanding issues, and describe planned development activities supporting a broader use potential to include sites with ELTs.
