葡萄牙采购需求：Gnss 天线、Gnss 接收器、GPS 和 Gnss、GPS Gnss、蓝牙 Gnss、Chc Gnss

I'm currently looking to expand our inventory and am particularly interested in drones. Could you provide me with detailed information about your available models? I'm curious about specifications like battery life, payload capacity, and any advanced features you might offer. Additionally, I'd appreciate insights into your pricing structure, lead times for ordering, and any bulk purchase discounts available. It would be great if you could also include information on warranty or after-sales support, as those are important factors in our decision-making process. Thank you!
