Getting ready to finalize my intial GPS purchase at DIYSTORE. Found data sheet, custom binary protocol reference, and MTK commands manual for Mediatek MT3329. No similar information regarding UBlox5.
Does this mean DIYDRONES project leans toward the Mediatek GPS?
Which of these units would you buy as your first?
Mark, could you possibly give further details about why the uBlox is the best over the MediaTek (or other GPS units? Does it provide a more consistent satellite lock? Faster sat lock? I too am looking to purchase a GPS module soon and I don't want to buy the uBlox for nearly 3 times the cost of the MediaTek unless there is good reason to do so. Thanks for any advice and personal experience you can provide.
I like the uBlox documentation, and uCenter configuration software. With true 4 Hz updates. I don't have experience with MediaTek software so it may be good too.. I agree 1/3 cost is hard to beat.
My uBlox gets a 3D/DGPS lock indoors after aiding data update & 20 minutes to acquire WAAS data from L Band SV-138 , it will hot start afterwards in a few seconds.
I am trying to decide between the Ublox and the MediaTek for my ArduPilot Mega project. I have seen posts where the MediatTek has lost satellite lock in high bank situations. I also noticed that the MediaTek appears to
be 10hz while the Ublox is only 4hz. The MediaTek3329 is only $38 while the uBlox5 is $86. From those of you who have flown both with the ArduPilot, which GPS would you buy and why?
BTW. I love this site and can’t wait to get started. Thanks for making available the hardware and information to actually build our own UAV.
