TBAD Presentation and Training at Gemini North (August 28-29, 2014)

On late August 2014 I was invited to attend a two-day TBAD (Transponder-Based Aircraft Detection) presentation and training at Gemini North in Hawaii.

The first day (August 28th) was dedicated to presentations from the system's creator (Tom Murphy, UCSD) and from Keck's Paul Stomski about their experience as early adopters.

The second day (August 29th) was spent at the summit testing their system.

Notes:
- Gemini antenna on ring, not behind secondary.
- Test the effect of vignetting with an airplane flying close to the telescope.
- Issue raised: TBAD does not provide early warming, like spotters. Tom M. says that he is thinking about it for next generation.
- Interference at Keck caused by fluorescent lights.
- TSIM cable: Keck will use Series 400 instead of RG-58 for lower losses at large distance.
- TSIM mount place: bridge crane (Subaru)
