Using GPS in my phone to record a trip, the battery gets drained pretty quickly. A fully charged battery gets down to about 30% in 3 hours. I would like to try building myself a GPS logger, prefer the design to be as small as possible to put in a backpack.
There seems to be many different choices of selection. Adafruits 26mm x 35mm Ultimate GPS Breakout seems ideal, with 15mm x 15mm antenna and 64K internal data logging for about 4K data points. A recent 18mm x 38mm NavSpark with detachable 1x1 antenna that offers GPS with 50MIPS + 500KB memory for user programming seems another interesting choice.
My question is how much does antenna size affects GPS performance? Would the Ultimate GPS be a good choice for my application? Or should I choose one with larger 1x1 antenna?
