Martin stated that a USB to SATA interface would kill his GPS. This is similar to my observations.
I have been perusing devices based on your initial links.
I am finding that GPS boards with the PI Zero form factor and USB connections typically are very expensive and relatively rare. For this version of the project, I cant use an external antenna: it will be lashed to the side of handheld radio and there is nowhere to effectively deploy the external antenna.
For the project I need to keep the UART connections on the GPIO header free for the next stage of the effort and besides if I am to allow multiple different types of GPS for the system, the other form factors all use USB GPS units.
I have found a number of GPS boards which fit the PI Zero form factor, have USB connection, and use a patch antenna using your links as a starting point, but they are typically more than $60 per board.
Since the GPS is an accessory to the main function, having the accessory exceed the cost of the remainder of the system seems odd.
Thoughts on where I might explore further?
Thanks!
I went down this path when I started, and dont seem to find reasonably priced GPS boards for this type of configuration.
I could add a UART to USB adapter tot he board: these can be cheap, but the system is now becoming increasingly kludgy.
