Hi there, I think I can help you with that, GPS units(at least, commercial ones) usually communicate with NMEA protocol over UART to output, I presume your system works differently ? Relevant Skills and Experience Embedded Systems, C, C++, Signal Processing, Kinematics Proposed Milestones $250 USD - Proof of concept, working prototype $416 USD - Final deliverable, together with test routines Additional Services Offered $1 USD - Any bug fixes and corrections. Are there any datasheet/specifications I can get my hands on ?
