Featherweight GPS 3-unit system

(GS + 2 trackers + 2 batteries)

To track a rocket, two units are required: a Tracker that flies on the rocket and the Ground Station which stays with you on the ground and communicates with your iPhone.

Options:

• Tracker only - optional battery available here. Don't forget the optional battery charger available here (Lots of people place a second order to get one.) The wire whip antenna option has equivalent LoRa performance and the antenna can stick through bulkheads to save space.
• Ground Station only - features an internal battery, micro-USB interface, and pocket-sized enclosure.
• Full System - includes a ground station with included battery, a tracker, and an extra 400 mAhr tracker battery with battery adapter. Don't forget the optional dual battery charger available here. (Lots of people place a second order to get one.)
• 3-way system - includes everything in the Full System, plus another tracker and tracker battery so you can easily track 2 of your rockets without needing to swap hardware.
