A custom board, nRF91DK or the Thingy:91?</p> <p>Either way, I recommend using an external antenna for the best performance and you should also have the device in an open area or at least outside a window since gathering GPS data from satellites can be quite sensitive, so if you have many restrictions between the device and the satellites you may not get a fix.</p><div style="clear:both;"></div>
