Abstract: Micro low-cost unmanned aerial vehicle (UAV) has the advantages of less restrictions for landing and takeoff, convenient transportation and relatively low cost. It is widely used in smallscale and decentralized regional photogrammetry, but the design of lowcost UAV have to tradeoffs and compromise between positioning accuracy, voyage, payload and many other aspects. Therefore, it is necessary to improve the efficiency of the lowcost UAV photography, build a lowcost fixedwing unmanned aerial vehicle, using Beidou／GPS combination positioning to increase the number of highelevation satellites to avoid the reduce of the positioning accuracy caused by the attitude changes; Two synchronized sport camera as the photography payload; the entire system cost control in less than ten thousand. According to the test flight time and the remaining power of the battery, this UAV have an operating time of about 1 hour and 30 minutes, and operating range about 70 km.
