5Hz GPS

[Unterhausen]

sparkfun is selling a 5Hz GPS now. http://www.sparkfun.com/commerce/product_info.php?products_id=8266
Beats the heck out of the 1Hz unit they were selling.
I don't remember the fastest you can buy, but 5Hz is probably pretty useful for a UAV

Unless a 5Hz data stream over runs the buffers in the device (PIC) that is reading and parsing the strings.

Workshop,

You have to hustle at 20 microseconds per bit. The 16MHz devices from TI can handle it but you probably need to use the GLL sentence to keep the message short.
