sensor package

Hello,I am looking at building or buying a sensor package. Mainly I need 3 axis accelerotometers, 3 axis gyros, magnetic sensors (3 axis would be best) and an altimeter. I want to read all the data into a gumstix or similar board and then downlink the data.I can and I have built systems like that before, but looking this like a hobby, I dont think I want to spend a lot of time designing, building and debugging electronics, so is not there a not-too-pricey sensor board?I checked the specs of MNAV100CA and looks like what I need, but it is kinda expensive at $1500. There is also uav development board by sparkfun, which does include a gps, and 2 axis accelerotometer and 2 axis gyro. no altimeter nor magnetic sensing.Is there a preferable open source board that does all the things I want. which route I must go if I dont want to spend whole lot of money.Best.

  • FYI, Crossbow has discontinued the MICRONAV, and is selling their remaining stock.
  • How about magnetometers (compass) There are 2 axis and 3 axis versions.

    I thought to get the perfect heading one would need a 3 axis sensor provided that the uav could be in different positions.

    However maybe I can get away with only 2 axis?

    Have a look at:

    http://www.sparkfun.com/commerce/product_info.php?products_id=236

    and

    http://www.sparkfun.com/commerce/product_info.php?products_id=244

    the first one is a 2 axis compass, where the second one is a 3 axis magnetometer.

    Is there a difference between a compass and a magnetometer. Can a 2 axis compass measure north without being parallel to the ground?

    Any ideas / recomendations?

    Best.
  • Has anyone tried the `INS 6 degrees of freedom - with gps` from openuav.astroplanes.com - its got almost what I want with the exception of altimeter.

    Best.

    I don't know of one with exactly what you want at under $1,000, but it's not too hard to design your own PCB and populate it with any sensor you want. Or maybe just add daughterboards to the SparkFun unit?
