Could I get away with not using GPS?
Complete beginner here. I'm building my first ever model rocket and decided to use an F-35-8 motor. According to OpenRocket, it should hit around 863 meters and have a descent time of roughly 170 seconds. I really want to avoid adding GPS as it would make it heavier. I'm adding basic sensors like the BMP280 and MPU6050, but don't want to design, buy, and set up a ground station for GPS. I added a buzzer just in case that activates when the rocket hits the ground.
