    Hi Guys,
    After reading a great article about the new RPi based detection setup I knew I needed to give it a try. I have played around with the idea of the UKMON setup, but upon reading this one it finally made it affordable to do!
    I’ve just received the RPi 3b+ with the real time clock, I just need the cooling fan and to install the software.

    Does anyone have a good source of the camera and lens?

    Also, can the RPi deal with more than one camera? It would like to have several in place on the roof 🙂 I’m also planning on making a portable setup to take to dark sky locations when we have meteor showers due to add an additional tracking station 🙂

    Looking forward to getting it up and running!

    Hi Tim!
    Could you please send me an e-mail using the contact form on this site, and I’ll send you the details by e-mail.

    Unfortunately not, even now it’s running at 70% CPU, plus it has to decode the H264 video stream in real time on the GPU. So it’s one camera, one Pi.

    Cheers,

    I’ve been running cameras since 2012 using the UFO suite but am interested in building a station using a Pi. I have everything I need except a camera and lens. Could you share details of suppliers and if possible part numbers.

    Many thanks

    Hello:
    First I would like to thank you for organising this program which is so very cool! I am close to building my first one and I would like to submit a question:

    How difficult would it be to include an inexpensive GPS module to provide an accurate clock/oscillator for the case if someone might like to make a portable camera (to bring along on camp-outs, etc). Having a GPS-based clock source would be very handy and not very difficult to implement into the existing software (hopefully).

    Any thoughts are appreciated!

    Dark skies,
    Don

    Hi,
    if a station has constant Internet access, the time on the Pi will by NTP synchronized. NTP synced time is usually precise to within one video frame, so millisecond precision is not really necessary. Even if the time is off by one second, the astrometric precision of meteor systems is too small for it to really matter.

    What really matters is precisely measuring geo coordinates of meteor cameras. People usually use Google Earth or smartphone GPS apps, but those coordinates can be off by 10+ meters. Our meteor camras have a precision on the order of 10s of meters at 100 km (average range to a meteor), so having precise coordinates is essential. We are looking for an easy and cheap way to measure geo coordinates to within a meter. That might be achieved by using inexpensive GPS modules and averaging the reported coordinates over several days, but we still haven’t tried that approach. There are also some high-precision GPS modules, but we are now talking about $200+ investment. Any development in this area would be much appreciated.

    Cheers,
    Denis
