Hey, for those interested in miniaturization, tech and flying things, here's the smallest complete long term GPS logger I've found around and developed for tracking peregrinations of living birds:
1.5 grams and 30x13.5x5mm in dimension, including: GPS, antenna, 512KByte Memory for 25,000 x 20 bytes locations, no microprocessor, battery + solar cell. No photo is yet available.
It can be implemented on a living bird as light as 30 grams (the logger shouldn't exceed 5% body weight).
It is developed and produced by T-Sheperd Solutions
and will be available soon.
Maybe of use for folks developing a nanoUAV?
