What next

What next ?

  • Software improvements

  • Examine higher sampling rates

  • Decide how we want to implement high-rate GPS

  • Build necessary infrastructure


Acknowledgements

What about PBO?

Acknowledgements

  • If we aren’t going to archive the 1-Hz data anyway, and the receivers are capable of tracking at 5 Hz, why not buffer at 5 Hz?
