NSLS-II in-house developed BPM systems provide better than 200nm resolution and sub-micron long-term position stability, combined with the high-temperature stability of the storage ring tunnel, electronic racks, sophisticated support structures and orbit feedback. The talk will start with brief introduction of the NSLS-II BPM button and electronics design and achieved performances. The talk will focus on recent developments based on the BPM electronics enhance the capability for advanced beam measurements, as well as the stable operation of the low emittance storage ring. Examples of such developments, like the BPM gated function, fast glitch detection, AC excitation and beam measurement results will be presented. Future developments like pilot tone calibration and a newer version of electronics will be discussed to continuously improve the stable/reliable operations and beam studies at NSLS-II.
