Hello, so I'm making a rocket with basic fuel and parachute to land, I wanted a GPS system in it so I know where is goes and where does it land, can someone please recommend me some parts that I can use with arduino nano and what antenna should I buy?
Thanks a lot
Would You know how to wire them up?
The GPS datasheet ought to know what's best.
Try a internet search on 'LoRa GPS Tracker' lots of stuff out there.
The 434Mhz ISM band is a good choice of frequency band as high gain yagi style antennas are readily available which can help when the rocket has landed on the ground and you need to receive the signal, and GPS location, from a long distance.
LoRa is good for receiving the actual GPS location as data.
But worth considering that depending where the rocket lands, there might not be GPS reception, so no location.
However long distance radio direction finding (RDF) can allow you to use a simple radio modules to get an accurate direction fix using a UHF handheld and a UHF yagi. I once got an accurate direction fix on a satellite in orbit using this method, when it was circa 1200km away.
GPS sensors are receive-only; they do not transmit. You will need to add a transmitter of some sort; LORA would probably be best. Since you will have line of sight to the transmitter until it is on land, you don't really need any kind of antenna other than whatever the LORA unit comes with or is described on the datasheet.
Qualify for an experimental permit from your area Aviation Administration. You can't just shoot stuff in the air. Be insured, for when your object falls onto something and causes adversity.
