I bought a U-blox with adapter from the store here, and started playing with it. I plan to put into my ground, SAGAR. Details -> http://www.billporter.info/?p=95
Anyway, the adapter board makes very poor contact with the GPS. sitting on the table next to me, I have a great GPS lock, but if I look at it the wrong way, I don't get data from it, and have to gently wiggle or apply pressure to the board to keep good contact.
This is going to be a problem for the vibration of a ground drone. Has anyone had this problem before? Are there any quick DIY solutions to keep good contact between the adapter board and GPS? Thanks.
