MediaTek vs U-Blox5 GPS units?

Posted by Mark Harrison on February 13, 2011 at 5:01pm

I'm getting ready to order the uDrones assembled board set.  It comes with the MediaTek GPS board standard, and offers an upgrade to the U-Blox5 for an extra $50.

 

What's the difference between the two units?  Better GPS reception? More features?

 

Many TIA!

    Just to be pedantically clear on this, is it suggested that the MediaTek is now the preferred GPS for folks getting started with basic APM UAV operations?

    The ublox firmware is considered superior by the Paparazzi folks who tested a truckload of GPS units a few years ago. It has an optional binary protocol that is easier/faster/less code to parse than NMEA. OTOH, the helical antenna is not optiimal for UAVs. But I would still take the ublox. Fragile or not.

    The uBlox has a helical antenna, which can offer better accuracy in high-bank maneuvers. But it's a larger, more fragile unit, so we recommend the MediaTek for most people.
